For EV drivers without home charging, or on long trips, public chargers are essential. They vary widely in speed, price, and how you pay.
A little planning makes public charging painless.
The three speeds
- Slow and standard AC chargers (up to about 22 kW): lamp posts, car parks, workplaces — best for overnight or all-day top-ups
- Rapid DC chargers (around 50 kW): add significant range in under an hour
- Ultra-rapid DC chargers (100 kW and above): motorway hubs, can add hundreds of miles in 20 to 30 minutes on compatible cars
Your car sets the limit
An EV can only charge as fast as its own hardware allows. A car with a maximum of 50 kW will not charge faster on a 350 kW charger. Charging also slows as the battery fills, usually beyond about 80 percent, so rapid stops are most efficient between roughly 10 and 80 percent.
Connectors
Connector standards vary by region. Most AC charging uses a Type 2 cable (in Europe) or J1772 (in North America), often your own cable. Rapid DC chargers have tethered cables, commonly CCS, with NACS (the Tesla-originated standard) increasingly common in North America.
Paying and costs
Many chargers now accept contactless card payment; others need an app or account. Public rapid charging usually costs significantly more per kWh than home charging. Subscription plans can reduce the price if you charge publicly often.
Plan ahead
Use a charging map or your car’s route planner to find chargers and check whether they are working. Have a backup option on longer trips. Preconditioning the battery on the way to a rapid charger, if your car supports it, speeds up charging in cold weather.
