Audi Q6 E-Tron | 255 KM Range with a 10-Minute Charge!

Did a fast-moving Tesla catch your eye recently? Asyou all know, American company produces the fastest production car on earth. You might be wondering what type of engine it uses to get that fast. Here is the answer:
<a href="https://www.licarco.com/news/how-many-tesla-cars-have-been-sold">Tesla vehicles</a> don&#8217;t have engines. While traditional vehicles have internal combustion engines, Teslas come with electric motors and large battery packs to power them. And furthermore, there is neither a petrol/diesel engine nor any fuel tank, fuel injection system, exhausts, etc. inside Tesla&#8217;s fully-electric models. The whole driving system is based on relatively small motors and thousands of battery cells placed underneath the vehicle.
Related Article: <a href="https://www.licarco.com/news/do-teslas-need-oil-change-tesla-maintenance-guide">Do Teslas Need Oil Change?</a>
To better understand how an engineless Tesla move, you need to know about an EV&#8217;s critical parts. The electric motor and the battery pack are two of the most significant systems on any <a href="https://www.licarco.com/news/10-advantages-of-owning-an-electric-vehicle">electric car</a>. But manufacturers aren&#8217;t simply putting some batteries and motors together to create a vehicle. There is more to it than you could guess at first glance.
The inverter, DC/DC converter, on-board charger, battery management system (BMS), and thermal management system (including heat pump) are equally crucial for the electric vehicle to move. Tesla got rid of engines, exhaust, and fuel systems. Instead, they put in more efficient, lighter equipment that guarantees a much faster, cleaner ride. Here is a list of parts that a regular Tesla vehicle equipped with:
&#8211; Power/Traction Battery Pack
&#8211; AC/DC Electric Motor(s)
&#8211; Power Inverter
&#8211; Transmission (mostly a reduction gear, to be precise)
&#8211; OBC (On-board Charger) and Charge Port
&#8211; DC/DC Converter
&#8211; 12V Auxiliary Battery (mostly lead-acid batteries used)
&#8211; Battery Management System (BMS)
&#8211; Thermal Management System (including heat pumps)
&#8211; Power Electronics Controller

At first, Tesla vehicles used a single-motor drivetrain. The first dual-motor AWD Tesla <a href="https://www.youtube.com/watch?v=FZ6lZJWL_Xk&amp;t=1s">unveiled in 2015</a>. After that Elon Musk&#8217;s company developed a tri-motor drivetrain powerful enough to set multiple acceleration records in 2021. Tesla Model S Plaid with tri-motor setup is still the fastest mass-production vehicle on the market.
Tesla Model S and Model X have both dual and tri motor drivetrains. The fully-electric Class 8 truck Tesla Semi is also powered by the same drive units with three electric motors. Rumors suggest that Tesla&#8217;s highly-anticipated electric pickup Cybertruck will also have three motors, instead of a quad-motor drivetrain originally promised. Tesla Model 3 and Model Y, on the other hand, offers both single-motor RWD and dual-motor all wheel drive options.

Do Teslas Have Engines? | A Guide to Understanding EVs

<a href="https://www.licarco.com/cars">Electric vehicles</a> are getting really popular, but the main concerns, such as short range and long charging times that hold conventional vehicle owners back from switching sides are still yet to be solved. That is where higher-voltage electric vehicles are coming into play. Tesla recently announced its 1000-volt system and hinted more Tesla vehicles will benefit from the new tech. Future EVs will eventually make the switch from 400V to higher voltage systems.
800V or higher voltage electric vehicles are capable of delivering <a href="https://www.licarco.com/news/top-15-ev-charging-networks-in-the-us">ultra-fast charging</a> rates and offer higher performance while improving the efficiency of the all systems. 800V electric vehicles can only be possible by employing an 800V battery and using SiC (Silicone Carbide) inverter, proper cabling, OBC (On-board Charger), DCDC converter and other electrical equipments that support higher voltage levels. Conventional electric vehicles come with 400V electrical architecture as standard. Because of the voltage limit, today&#8217;s electric vehicles are limited to a maximum of 400-volt when they are connected to a DC charging station. In order to reach higher charge rates, current levels should go up to 600A or even more, which is not ideal for the infrastructure that charging stations heavily rely on.
The first higher-voltage EV is the Porsche Taycan, which has a cutting-edge 800V inverter built-in. Its DC charging rate can go as high as 270 kW with the proper charging setup. After that Hyundai and Kia developed an alternative 800V charging tech to avoid using an expensive 800V SiC inverter. In late 2021, Lucid Motors launched its first vehicle Lucid Air with an industry-leading 924V system developed by <a href="https://eepower.com/news/wolfspeed-announces-the-lucid-air-is-using-its-sic-power-modules/#">Wolfspeed</a>. And one year later, Tesla unveiled its first 1000V vehicle architecture with the launch of the tri-motor electric truck Tesla Semi. <a href="https://spectrum.ieee.org/ev-charging-800-volt">General Motors</a>, Volkswagen, and, of course, Chinese brands such as Aion, Avatr, Xpeng, Zeekr, BYD, Voyah and Li Auto have also been developing 800V high-voltage electrical systems for their EVs.
In this article, we researched our way into higher voltage electric vehicles and created a list of benefits of owning an 800V EV.
<h2>Faster Charging Compared to 400V Electric Vehicles</h2>
<img loading="lazy" decoding="async" class="alignnone size-large wp-image-32268" src="https://api.dolubatarya.com/wp-content/uploads/2023/01/ionity-ultra-fast-charging-stations-1024x683.jpg" alt="" width="750" height="500" srcset="https://api.dolubatarya.com/wp-content/uploads/2023/01/ionity-ultra-fast-charging-stations-1024x683.jpg 1024w, https://api.dolubatarya.com/wp-content/uploads/2023/01/ionity-ultra-fast-charging-stations-300x200.jpg 300w, https://api.dolubatarya.com/wp-content/uploads/2023/01/ionity-ultra-fast-charging-stations-768x512.jpg 768w, https://api.dolubatarya.com/wp-content/uploads/2023/01/ionity-ultra-fast-charging-stations-1536x1024.jpg 1536w, https://api.dolubatarya.com/wp-content/uploads/2023/01/ionity-ultra-fast-charging-stations-1568x1045.jpg 1568w, https://api.dolubatarya.com/wp-content/uploads/2023/01/ionity-ultra-fast-charging-stations.jpg 1920w" sizes="(max-width: 750px) 100vw, 750px" />
800V or higher voltage systems allow electric vehicles to be charged at as high as 480 kW, <a href="https://www.licarco.com/xpeng-g9-awd">Xpeng G9</a> proved. Regular 400V electric vehicles aren&#8217;t capable of doing that, because of the charging infrastructure&#8217;s current limit. When you plug your 400V vehicle into a DC charger, you limit your session to 400-volt. To provide faster charging speeds, EV charger should deliver more current, sometimes as high as 600A or even more (The third-gen Tesla Superchargers can deliver up to 660-amper). In order to increase the current, thicker and water-cooled cables are needed. Even using these expensive cables are not enough to lower down the charge efficiency, as conduction losses will increase up to nine times.
EV manufacturers have been developing 800V charging technologies to overcome this fast-charging problem. Some companies such as Porsche/Audi, Lucid Motors, and Xpeng use SiC inverters inside their EVs. These next-gen SiC inverters can handle higher voltages and also improve efficiency. Hyundai and Kia took a different approach to this matter. Korean automakers developed a technology that manages to provide 800-volt charging by using electric motors as generator and a regular IGBT inverter.
Thanks to more advanced electronics, 800-volt charging enables vehicle owners to reach up to 480 kW DC charging rates. For instance, Xpeng G9 and Aion LX Plus are already on sale that support ultra-fast 480+ kW charging. Lucid Air can go as high as 300 kW. Porsche Taycan did perform similiarly. Hyundai Ioniq 5 and Kia EV6 is also capable of delivering up to 240 kW DC charging speeds. 800V charging is definitely the future of EVs!
<h3>More Efficient &amp; More Powerful Electric Drivetrains</h3>
<img loading="lazy" decoding="async" class="alignnone size-large wp-image-32291" src="https://api.dolubatarya.com/wp-content/uploads/2023/01/lucid-motorsports-edu-tech-1024x696.jpg" alt="" width="750" height="510" srcset="https://api.dolubatarya.com/wp-content/uploads/2023/01/lucid-motorsports-edu-tech-1024x696.jpg 1024w, https://api.dolubatarya.com/wp-content/uploads/2023/01/lucid-motorsports-edu-tech-300x204.jpg 300w, https://api.dolubatarya.com/wp-content/uploads/2023/01/lucid-motorsports-edu-tech-768x522.jpg 768w, https://api.dolubatarya.com/wp-content/uploads/2023/01/lucid-motorsports-edu-tech-1536x1044.jpg 1536w, https://api.dolubatarya.com/wp-content/uploads/2023/01/lucid-motorsports-edu-tech-1568x1066.jpg 1568w, https://api.dolubatarya.com/wp-content/uploads/2023/01/lucid-motorsports-edu-tech.jpg 1938w" sizes="(max-width: 750px) 100vw, 750px" />
By switching to a 800V architecture, EV manufacturers can make use of higher voltage motors as well. Porsche is the first company to implement an 800V electric motor into its vehicles. Higher voltage improves overall power density of the motor unit and it reduces the maximum torque required to achieve the same output power due to extended RPM range.
As the DC link voltage of the EV motor units increase, the current levels decrease. This leads to lower copper loss and improves efficiency of the electrical traction systems. Higher voltage motors are also tend to produce more power than lower voltage solutions.
From the efficiency perspective, the next-gen SiC inverters used inside 800V electric vehicles are also much more efficient. <a href="https://www.licarco.com/byd-yangwang-u8">BYD recently unveiled</a> its first SiC inverter developed in-house, which scores an efficiency level of 99.5 percent.
<h3>800V Architectures Mean Lighter Electric Cars</h3>
<img loading="lazy" decoding="async" class="alignnone wp-image-32293 size-large" src="https://api.dolubatarya.com/wp-content/uploads/2023/01/electric-vehicle-cabling-hybrid-drivetrain-1024x683.jpg" alt="" width="750" height="500" srcset="https://api.dolubatarya.com/wp-content/uploads/2023/01/electric-vehicle-cabling-hybrid-drivetrain-1024x683.jpg 1024w, https://api.dolubatarya.com/wp-content/uploads/2023/01/electric-vehicle-cabling-hybrid-drivetrain-300x200.jpg 300w, https://api.dolubatarya.com/wp-content/uploads/2023/01/electric-vehicle-cabling-hybrid-drivetrain-768x512.jpg 768w, https://api.dolubatarya.com/wp-content/uploads/2023/01/electric-vehicle-cabling-hybrid-drivetrain-1536x1024.jpg 1536w, https://api.dolubatarya.com/wp-content/uploads/2023/01/electric-vehicle-cabling-hybrid-drivetrain-2048x1365.jpg 2048w, https://api.dolubatarya.com/wp-content/uploads/2023/01/electric-vehicle-cabling-hybrid-drivetrain-1568x1045.jpg 1568w" sizes="(max-width: 750px) 100vw, 750px" />
800-volt electrical architectures can be created by using thinner cables between the battery pack and the inverter, DC charging port, OBC, and other equipments. As a result, 800V electric vehicles will use less copper and that would reduce the overall weight of the car.
Higher voltage electric motors are also significantly lighter and more power-dense than regular lower voltage units. That means 800V electric vehicles can be equipped with smaller, lighter motors. That creates more room for batteries as well.
<h3>Reduced Cost of Cabling, Less Copper Used Inside the Vehicle</h3>
Electric vehicles use more copper than any other vehicles. It takes 2 to 4 times more copper to build an EV than an ICE vehicle. But unlike 400V EVs, higher voltage systems don&#8217;t require thick copper cables. That will not only help manufacturers reduce the cost of cabling but also ease up the global copper supply chain. Because EV batteries and heavy investments in EV charging infrastructure have already been causing problems for the copper industry, thinner cables will help in the near future.
Here are some disadvantages of choosing 800V electrical system over a regular 400V architecture:
&#8211; Higher cost of electrical insulation and clearance
&#8211; Higher voltage battery packs tend to perform less reliable than 400V systems, because they contain larger number of series connections. The impact of single cell failure in a pack like this would be much higher than the 400V batteries with more parallel cells.
&#8211; Lower voltage battery packs are more energy-dense than the similiarly designed 800V batteries, which is the result of all the additional electrical clearance requirements around high voltage systems and the much larger BMS.

What is 800V Electric Vehicle? | What are the Benefits of 800V Systems?

In the automobile world, there is a relentless struggle to increase the range of all-electric vehicles. Today, we brought the news about the <a href="https://www.licarco.com/news/zf-heated-seat-belts-to-increase-range-in-electric-vehicles">heated seat belt</a> that will contribute to the range of our agenda. This time we will talk about a more advanced solution.
Texas Instruments introduced two new generation tracking chips for battery packs and cells. These chips, which the BMS will utilize (Battery Management System), which is responsible for the management of electric vehicle batteries, manage to reduce the voltage accuracy level from 3.5 mV in the previous generation to 1 mV.

There are thousands of cells in a car battery pack. It is of great importance that charge/discharge cycles are carried out by determining values such as voltage, current, temperature, charge level, and cell health level of each cell. Manufacturers designing increasingly advanced BMS solutions can provide significant efficiency. It enables increasing vehicle range if they can determine the state of the battery with the highest accuracy.
In this regard, USA-based Texas Instruments, one of the largest semiconductor chip suppliers in the industry, can reduce voltage accuracy up to 0.05% with its newly developed battery pack and battery cell monitoring chips. Thus, the battery&#8217;s cell state of charge will be identified 3.5 times more precisely than it is now.
<h2>Greater Range Advantage for LFP Batteries</h2>

Products with high sensitivity to voltage will provide a serious advantage, especially in batteries equipped with LFP cathode cells. Because LFP batteries&#8217; voltage level is almost constant during the discharge cycle of 70% to 30% due to their chemical structure. For example, LFP batteries are the cell type that puts the BMS&#8217;s hardest in determining the charge level.
Texas Instruments will enable high-accuracy monitoring of LFP batteries with its new chip. These chips work 3.5 times more accurately in voltage monitoring. The company&#8217;s new chips will be able to increase the range by up to 20 % with the existing battery. A highly accurate battery management system will also help to make more accurate range estimations of electric cars.
It is certain that we will see much longer-range values in the coming years in electric cars.

New Generation Chips To Increase the Range of EVs by 20 %

Mercedes-Benz

Electric vehicles are transforming every aspect of the automotive industry. The new solution introduced by the German ZF today shows that even heated seat belts will change with electric vehicles.
The product, called the “Heated Seat Belts”, is formed by knitting conductors of one rope thickness into the belt fabric. The belt can reach 40 degrees in seconds with only 70 watts of power. It will allow the driver and passengers to warm up quickly on cold days.
<h2>Why Is a Heated Seat Belt Needed and How Does It Affect Range in an Electric Vehicle?</h2>
<img loading="lazy" decoding="async" class="aligncenter wp-image-32002 size-large" src="https://api.dolubatarya.com/wp-content/uploads/2023/01/zf-heat-belt-threads-1536x864-1-1024x576.jpeg" alt="" width="750" height="422" srcset="https://api.dolubatarya.com/wp-content/uploads/2023/01/zf-heat-belt-threads-1536x864-1-1024x576.jpeg 1024w, https://api.dolubatarya.com/wp-content/uploads/2023/01/zf-heat-belt-threads-1536x864-1-300x169.jpeg 300w, https://api.dolubatarya.com/wp-content/uploads/2023/01/zf-heat-belt-threads-1536x864-1-768x432.jpeg 768w, https://api.dolubatarya.com/wp-content/uploads/2023/01/zf-heat-belt-threads-1536x864-1.jpeg 1536w" sizes="(max-width: 750px) 100vw, 750px" />
Since <a href="https://www.licarco.com/search?_=electric%20vehicle">electric vehicles</a> do not have an inefficient internal combustion engine and cannot use the heat emitted by this engine, the PTC heater or heat pump must be operated by using the energy in the battery to warm the cabin on cold days. The energy spent on heating can cause range loss of up to tens of kilometers in some cases.
ZF develops a heated seat belt in the most compact way possible based on the request of the automobile industry. This solution can be quickly integrated into the mass production line of existing cars. It looks like a normal belt and is produced in a normal belt thickness.
According to the calculation of the German company, the electric car range, which decreases during the winter months, can be extended up to 15% thanks to this belt. The seat belt, which may instantly heat the driver or passenger&#8217;s upper body and waist, is not a new concept. In 2018, it was shared that Ford received a patent for a similar belt. The following year, a heated belt was also used in a safety vehicle developed by Mercedes. However, a solution as compact as ZF and in a form that can be integrated into existing production has not been offered to the market until now.
In order to minimize the seasonal range difference in electric vehicles, not only heated belts are developed. Advanced heat pumps that enable heating/cooling in a shorter time with less energy compared to PTC heaters, thermal management systems, and BMSs that provide high-accuracy tracking of batteries and battery cells indicate that the concept of winter range will not be as scary as it is today in the next few years.

ZF Heated Seat Belts to Increase Range in Electric Vehicles

In a drive to increase employment as it speeds up battery production, Tesla has officially launched its Megafactory in California. With the addition of the new production plant, Tesla&#8217;s Energy division is anticipated to grow significantly. The company just deployed 2.1 GWh of battery-based energy storage systems, breaking its own quarterly record.
More than 10 GWh will be added every three months until the Lathrop facility is completed. That will represent a paradigm shift for the whole sector and might be of enormous assistance to utility companies searching for elevated and cost-effective battery solutions.
&nbsp;
<h2>Tesla Plans to Generate 40 Gwh Of Megapacks at its Megafactory Per Year</h2>
The Lathrop site is rather large since 40 GWh of Tesla Megapack systems are expected to be produced there annually based on the company&#8217;s 2021 announcement. About 3 MWh, together with all required power electronics, may fit within one Megapack container. Tesla should be capable of producing well over 13,000 Megapacks annually at a capacity of 40 GWh. In comparison to its 2021 production, that represents a significant rise.
Tesla will benefit from using massive BESS, such as the Megapack, large volume serial production, and the lithium iron phosphate (LFP) battery chemistry. Additionally, Tesla has disclosed plans to use LFP cells in its Model 3/Model Y entry-level automobiles and energy storage systems.
Currently, BESS only contributes a small percentage of Tesla&#8217;s overall income, and its margins are substantially lower than those of its automobiles. Because the firm is rapidly growing its EV business, it is predicted that BESS share will keep around 10% for the coming years.

<h2>How the BESS System Works</h2>
An energy storage system (ESS) known as a battery energy storage system (BESS) collects energy from various sources, gathers it, and preserves it in rechargeable batteries for subsequent use.
A BESS is a hybrid system that combines both low- and high-level software with hardware components. The key components of BESS include:
<ul>
<li>A battery system (BS)</li>
<li>A battery management system (BMS)</li>
<li>An inverter or a power conversion system (PCS)</li>
<li>An energy management system (EMS)</li>
</ul>
If necessary, the battery&#8217;s electrical and chemical energy may be discharged and provided to electric cars.
