Here’s a chart detailing EV charging rates in miles added per hour based on common charger amp rates and temperatures in °F. Note that actual values vary depending on the EV model, battery efficiency, and charger type. These are generalized estimates for Level 2 chargers (240V), with an assumption of average EV efficiency at 3.5 miles/kWh:

Charger Amps	Power Output (kW)	Miles Added Per Hour (70°F)	Miles Added Per Hour (50°F)	Miles Added Per Hour (30°F)	Miles Added Per Hour (10°F)
16 amps	3.8 kW	13 miles/hour	12 miles/hour	10 miles/hour	9 miles/hour
32 amps	7.6 kW	26 miles/hour	24 miles/hour	21 miles/hour	18 miles/hour
40 amps	9.6 kW	33 miles/hour	30 miles/hour	26 miles/hour	23 miles/hour
48 amps	11.5 kW	40 miles/hour	36 miles/hour	32 miles/hour	28 miles/hour

Explanation:

1. Power Output (kW): Calculated as volts (240V) × amps × 0.85 (efficiency factor for Level 2 chargers).
2. Temperature Impact: Cold weather reduces battery efficiency due to increased energy use for heating and reduced chemical reaction rates inside the battery. The table includes estimates based on reduced efficiency at lower temperatures
