Advancements in technology have led to significant improvements in the fast-charging capabilities of electric cars. This means that drivers can now spend less time waiting at a DC public charger while on the road. In the past, Level 3 chargers could provide a maximum of 150 kilowatts of power. However, the introduction of 350-kW chargers has become more common, resulting in super-fast charging for compatible vehicles. One way automakers are achieving this improved charging speed is through higher voltage, particularly with the implementation of 800V charging systems.
So, what exactly is the difference between 800-volt charging and 400-volt charging? Essentially, the higher the voltage, the lower the amperage or current required to charge the vehicle. This means that with higher voltage, more wattage or power (also known as charge rate) can be obtained from the same current. In addition to this, 800V architecture is more efficient due to reduced electrical resistance. As a result, thinner cables and smaller, lighter components can be utilized while requiring less cooling. However, it is important to note that the adoption of 800V charging comes with increased costs, which are ultimately passed on to consumers. While automakers do not provide a breakdown of pricing specifically for the 800V system, consumers must evaluate the overall pricing of the vehicle when making a purchasing decision.
It’s worth mentioning that not all EVs with 800V charging capability possess 800V vehicle architecture. For example, both the GMC Hummer EV and Chevy Silverado EV operate at 400V. However, they can switch to 800V charging temporarily by connecting their dual battery packs in series. At present, there are only a limited number of EVs available that offer 800V charging. Nevertheless, if you anticipate taking longer trips and using DC fast chargers frequently, opting for a vehicle with faster charging capability is worth considering.
Here are the EVs available with 800V charging either currently on sale or set to be released in 2024:
– Audi E-Tron GT
– Chevrolet Silverado EV
– Genesis GV60
– Genesis Electrified G80
– Genesis Electrified GV70
– GMC Hummer EV Pickup
– GMC Hummer EV SUV
– GMC Sierra EV*
– Hyundai Ioniq 5
– Hyundai Ioniq 6
– Kia EV6
– Kia EV9
– Lotus Eletre*
– Lotus Emeya*
– Lucid Air
– Lucid Gravity*
– Porsche Macan Electric*
– Porsche Taycan
– Ram 1500 REV*

It’s worth noting that some of these vehicles are scheduled for release later in 2024. Nevertheless, for those who prioritize fast charging capabilities and anticipate relying on DC fast chargers frequently, choosing an EV with 800V charging technology may be a wise decision.
