Charging speed

Our AmpCharge public EV chargers have a range of power outputs (ranging from 75-400kW). Real-life charging speeds and times are not guaranteed as they depend on a wide range of factors other than just a charger's power output rating such as:

• the number of EVs charging concurrently at the site,
• available grid capacity at the site,
• your EV's specifications including the maximum charge rate, battery size and capacity and the state of battery charge at the time of the charge,
• external factors such as weather.

Please note that charging speeds may be reduced to account for these factors.

Exact charging speeds and times depend on various factors such as a charger's power output, the number of EVs charging concurrently at a site, available grid capacity, and an EV's specific characteristics such as maximum charging rate, battery size and capacity, state of battery charge at the time of the charge and external factors such as weather. Charging speeds may be reduced to account for these factors.

As a rule of thumb, the higher power output capacity of a charger (measured in 'kilowatts' or 'kW'), the faster the charge.

However, exact charging speeds and times do not only depend on the power output capacity of a charger but are impacted by a wider range of factors (see other FAQs for more detail).

Please check you EV's charging specifications to see what your 'maximum charging rate' is. This refers to the highest power (measured in kW) that your EV's battery and onboard system can accept. For example, if your vehicle's maximum charging rate is 100kW, you can still use a 150kW rated (or faster) charger, but your vehicle will only accept up to 100kW at a time from that charger.
