Cybertruck charge time is 20 minutes at 350kW V4 Supercharger as Tesla splits the battery in 400V units

Chinese phone makers and EV companies may have given Tesla a pretty smart idea when it comes to faster Cybertruck charging. The Cybertruck is Tesla's first vehicle to run on the modern 800V architecture but such chargers are few and far between.

Tesla apparently splits the Cybertruck's 123 kWh battery pack capacity in 4 x 200V units that a switch sends from running in series to two units running in parallel that can charge at 400V simultaneously for faster top-ups and backward compatibility with existing infrastructure.

• 20 minutes at V4 Supercharger

That's all fine and dandy, but how fast can the Cybertruck actually charge? In the Cybertruck specs, Tesla says that it can take 250 kW max because this is the output that its current generation of V3 Superchargers tops out at.

What about charging the Cybertruck at the newer V4 Superchargers which Tesla officially rates as capable of 350 kW charging? Well, Tesla's head of engineering confirms in the Cybertruck review by Top Gear (at the 34:04 mark) that it will take less than 20 minutes to bring it from 15%-85% at a V4 Supercharger that is able to deliver 350 kW.

That is pretty quick considering that the electric pickup carries the largest Tesla battery this side of the Semi. The V4 Supercharger stations that Tesla is currently rolling out across Europe and North America, however, are still housed in V3 cabinets and deliver the same 250 kW output.

When Tesla has enough fast-charging EV models or Cybertruck units shipped, it will probably start upgrading the grid infrastructure around its V4 Superchargers and their cabinets to their max 350 kW output that takes 20 minutes to charge a Cybertruck.

Apart from the Cybertruck, however, there are other 800V EVs on the road from Hyundai, Kia, or Porsche, not to mention the Chinese EV makers. Since everyone seems to be moving towards Tesla's NACS connector standard, it may not be long before we start seeing the first real 350 kW V4 Supercharger stations by Tesla that can also be used by other EVs with 800V architecture for faster charging.
