How many miles of charge can I get from a Volta station?

The number of miles of driving you can get from a charging session depends on several factors.

These factors include: 

  • How much power (“charging speed”) the station can deliver, measured in kW
  • How much power the vehicle can accept, measured in kW
  • The duration of your charging session
  • How much energy your vehicle’s battery can store, measured in kWh
  • The efficiency of your vehicle, measured in miles/kWh

Other factors that can influence your vehicle’s charging capacity and speed:

  • The charge state of your battery: most vehicles reduce the charging speed significantly as the battery approaches 90%-100% of charge, sometimes as early as 70%-80%.
  • Battery temperature: Most vehicles reduce charging speed when the battery is too cold or too hot.
  • Imbalanced battery cells after a longer period of driving or charging. Check your vehicle’s manual to see if you can prepare your battery for optimal charging in advance of a session.

The maximum charging speed Volta chargers can deliver are:

  • L2: 6-10 kW, or up to 35 miles of range per hour of charging. Note that miles per kWh vary from ~2 to ~4 miles per kWh depending on your vehicle.
  • DC fast: 50 kW and faster, or up to 210 miles of range per hour of charging, depending on your vehicle.
