VW is preparing a software update for its ID. series electric cars that increases peak charging speed from 125kW to 135kW on the largest 77kWh battery.
The 3.0 software also includes improvements to navigation, voice control, and driver assistance.
While 10kW might sound like a minor improvement (only 8%), it actually cuts charge time from 38 minutes to 29 minutes for a 5–80% charge. The reason for this is a significant shift in charge curve and a slower taper.
Batteries typically charge fastest when they are close to empty, and charging needs to slow down as the battery gets fuller.
