The Chevrolet Bolt EV, as depicted in the graph above, can charge at its full ability when connected to a 125A 50 kW charger once it reaches 20C (68F) but at 8C (46F) it can only safely charge at around 60A or 20 to 25 kW. At colder temperatures the charge rate is even slower, although it isn’t shown on this graph. The Bolt can charge at up to 150A at 68F or warmer when connected to a more powerful charger.
