1st Tesla Cybertruck Charging Session on an 800-volt NACS Charger Achieves Peak 327KW Charging – 30% Faster Than the 250KW Limit at Tesla’s V3 Superchargers

Although the Cybertruck is built on an 800-volt architecture, due to the limitations of Tesla’s V3 superchargers, it has been limited to charging at 400 volts and 250KW. However, the 1st 800-volt Cybertruck charging session shows the vehicle’s capability.

Regarding electric vehicle fast charging, there are currently three significant developments to be excited about.

First, Tesla is opening up its superchargers to third-party EVs; second, the Tesla charging plug has been adopted as the official North American Charging Standard (NACS); and third, Tesla’s V4 superchargers are starting to roll out.

On the V4 superchargers specifically, the next-generation Tesla charging stalls are particularly exciting because they provide a longer cable that can easily reach more vehicle types. Also, V4 superchargers are expected to offer higher charging speeds of up to 350KW at 800 volts.

The current generation V3 Tesla superchargers are caped at 250KW and charge vehicles at 400 volts. Until the Cybertruck, all Tesla vehicles used a 400-volt architecture, so this wasn’t an issue.

However, with the Cybertruck and other 800-volt vehicles hitting the streets, V3 superchargers cannot charge them at their peak capacity.

For example, for the Cybertruck, Tesla artificially splits the truck’s 800-volt batteries into two 400-volt battery packs, which is how the company is able to charge at the 400-volt V3 superchargers.

The Cybertruck is currently capped at an artificial 250KW peak charging speed using this approach. However, Tesla’s head of vehicle engineering, Lars Moravy, has said that using V4 superchargers, the Cybertruck will be able to hit peak charging speeds of 350KW.

Unfortunately, Tesla has yet to start rolling out V4 superchargers in the US, which is where the Cybertruck is currently on sale.

However, this brings us back to one of the exciting developments in the fast-charging space. Since the Tesla charging plug has been adopted as the North American charging standard (NACS), third-party charging companies can now build charging stalls using Tesla’s NACS connectors.

This is precisely what the charging startup Nxu, Inc. has achieved. The company wrote in a press release, “NxuOne™ Makes History as the First Reported Third-Party Charging System to Harness Tesla Cybertruck's 800V Architecture.”

As I have already mentioned, the Tesla V3 superchargers are capped at 250 KW at 400 volts, which artificially limits the Cybertruck's charging speed.

However, Nxu, Inc., with its NxuOne charger, can dispense much higher charging speeds thanks to its 800-volt charger.

As mentioned in the press release, Nxu, Inc., is the first third-party fast-charging outlet to charge the Cybertruck at 800 volts.

At these higher voltages, the Cybertruck blasts ahead of the fastest supercharging speed recorded on a Cybertruck, 253KW, and charges at 327KW for the first time.

That’s more than a 30% improvement in peak charging performance thanks to the 800-volt chargers.

This is wonderful news for current and future Cybertruck owners, who can rest assured that their truck is future-proofed when it comes to charging speed.

Although exciting, 327KW is still below the 350KW peak quoted by Tesla’s VP of Vehicle Engineering, and the vehicle's charging curve can still be improved.

This is all the information we’ve got regarding the Cybertruck's charging speed improvements. However, we’ll keep you posted when we learn more about the issue. Until then, visit our site, torquenews.com/Tesla, regularly for the latest updates.

So, what do you think? Are you happy to see a Cybertruck being able to charge at 800-volt for the first time? Also, does this increase your excitement for Tesla’s V4 superchargers?  Let us know your thoughts in the comments below.
