Which EV Charger Should I Buy?

How to choose the charging power

At home or at work you charge with AC, and the speed is limited by the car's on-board charger. A car that takes 11 kW draws 11 kW even from a 22 kW charger, so the charger should not be weaker than the car's AC power; a stronger one does no harm.

Some cars charge on a single phase only (e.g. 7.4 kW). They use one phase of a three-phase charger and need 32 A on that phase for 7.4 kW: a 22 kW (32 A) charger delivers it, an 11 kW (16 A) charger stays at 3.7 kW.

Single-phase or three-phase?

Most flats and older buildings have single-phase supply (230 V), allowing up to 7.4 kW. Detached houses, villas, new buildings and workplaces usually have three-phase (400 V), allowing 11 or 22 kW. If the main breaker in your meter box has three poles, your supply is three-phase.

Tethered or socket?

A tethered charger has a Type 2 cable attached: park and plug in, the most practical option. A socket charger has a Type 2 outlet and you use your own cable; it suits places where different cars charge and a cleaner look is wanted.

Shared use at residential sites and workplaces

When several people use one charger, consumption must be measured and billed per user. A MID-certified meter measures each user's electricity legally; a charger with a SIM card (GSM) can be managed remotely even without Wi-Fi in the car park, and users start charging with a card or app. That is why we only recommend chargers with a SIM card and MID meter for shared use.
