Electric vehicles (EVs) are proliferating in California, with over 1.8 million operating in the state. Modern EVs have considerably larger battery packs than early models, in many cases 80-100 kWh for 250-300-mile driving ranges. Charging power for EVs is also increasing. With the appropriate wiring, residential charging at Level 2 has reached up to 19.2 kW though 7-10 kW is more typical, making EVs among the most demanding household power loads. These charging loads can stress local electricity distribution feeders, particularly in the early evening when power use typically peaks.
