Electric vehicle charging connection cable use requirements

China [CN]

There are many types of charging cable connectors commonly used in electric cars, and if you don't know what your car does, it's easy to tell them apart at a glance - but the manual will tell you too. The variants of cars that are compatible with fast chargers are Type 1 or Type 2, while those that are compatible with fast chargers are CCS or CHAdeMO.

The seven-pin Type 2 connector has become the more popular European standard for fast charging when using wall-mounted charging boxes (7-22kW), but many older cars use the Type 1 five-pin connector to charge at these speeds.

Power/Phase Rating

It is crucial to choose a charging cable that can carry enough current to charge your EV battery at the optimal time. Cables typically come in 16-amp and 32-amp formats, with the latter being heavier and thicker - it requires thicker wire to carry more current. A 7kW wallbox will provide 32 amps of power, while a 3.6kW wallbox is typically limited to 16 amps.

Sometimes it's worth purchasing a 32-amp cable even if your current car's on-board charger is only rated for 16 amps, as you may want to use the cable later for another vehicle with a higher rating. However, 32 amp cable is heavier and therefore a bit cumbersome to handle, which may put people off.

Home power supplies are generally single-phase unless professionally modified, but if you want to use other fast chargers at optimal speeds, you'll need a three-phase compatible cable. Three-phase cables are also suitable for single-phase charging setups.
