Hello Folks,

I own a 2013 Chevy Volt Premier. Have owned it since 2015, and it only has abou 45,000 miles on the odometer.

Always used the 120V Level 1 charger that came along with the vehicle. But recently I installed 32 Amps Level 2 Charger in my garage, and as expected it charges the Volt much faster than the one that came with the vehicle, but it seems to only feed up to 13.2Amps to the Volt. Is that a limitation of the Chevy Volt itself (that does the conversion from AC to DC) or is the new charger defective?
2013 Volt has a 3.3kW on board charger. Most Residential line voltage is actually about 246V
246 V x 13.2 A = 3,247. W. Or (3.25 kW) so thats about right if factor some line loss.

Your L2 unit can transfer up to 32A load but the vehicle onboard charger regulates the actual current to its maximum rating.

The maximum amps the Volt can pull is 16 IIRC.
“Can” is the key. Not necessarily will. 246V x 16A = 3.94 kW. That’s way more than the 3.3 kW onboard charger will allow.

Commercial properties typically run 208V. 208V x 16 A = 3.32 kW.
Makes it plausible for 16A maximum rating.
