Tesla's Powerpacks work by drawing excess power from electrical grids during off hours and storing it for later use. This allows charging stations to keep up with demand and helps to avoid increased prices during peak hours. The Powerpacks being used at Electricfy America charging stations will have a capacity of 350kWh and will be capable of 210kW fast-charging.

Volkswagen's Electrify America has been working to build out its electric charging infrastructure and currently operates nearly 500 stations across the country, including the first 350kW chargers in California. While it has been rapidly expanding the presence of its charging unit, Electrify America ran into issues last month when a short-circuiting plug caused the company to shut down a number of its high-powered stations. The issue was resolved days later and the chargers have since been brought back online.
