Tesla 2020.28.5 Software Update Brings 250 kW Max Charging to Model S/X

Tesla tonight released its 2020.28.5 software update tonight, which brings up to 250 kW peak charging rates at V3 Superchargers for select versions of Model S and Model X.

Specifically, Tesla hacker @greentheonly says the update allows Model S and Model X sold after June 2020 in the U.S. and Canada to support these new 250 kW peak charging rates. Recently, Tesla updated its website to indicate up to 250 kW max charging rates for Model S and Model X.

If your Model S or Model X has a battery pack with part number ending in ‘H’ or ‘G’, it means your vehicle is supported for faster max charging rates at V3 Tesla Superchargers.

Tesla’s 2020.28.5 software update was released earlier this evening and the release notes (via Teslascope) indicate, “Your car is now able to charge at V3 Superchargers at up to 250kW peak rates. As usual, when you navigate to a Supercharger, your car will condition its battery during the drive, so it can charge faster.”

Other new features include a passenger face vent change, where if nobody is sitting in your passenger seat, vents will be automatically disabled to lower energy consumption. Other changes include Sirius XM improvements, while “the Autosteer cruising set speed on residential roads can now be increased up to +5 mph (10 km/h) over the speed limit,” when one is using Traffic Light and Stop Sign Control (beta).

The release notes also note range display has been tweaked to “now display a slightly higher range to more accurately reflect the capacity of the battery,” while suspension improvements are also available.

The update also adds Polish language support, while Tesla Arcade has been removed for Model S and X owners in Hong Kong, following a previous removal of the feature from the Model 3 in the region last month.
