DC chargers provide higher power charging (which requires much larger AC-to-DC converters) by building the converter into the charging station instead of the vehicle to avoid size and weight restrictions. The station then directly supplies DC power to the vehicle, bypassing the onboard converter. Most modern electric car models can accept both ...
The DC−/L2 pin provides both the negative side of the DC voltage link or, when using AC, it can serve as either Line 2 in a split-phase connection or the neutral in a single-phase connection. The G, or Ground, pin provides a connection between the earth and the vehicle chassis. The ground pin is also used as a reference point for the CP and ...
CCS1 (Combined Charging System Combo 1) plug as used in North America. It is an extension of the J1772 standard AC charging connector.

The connector is circular in shape, with a flattened top edge; the original design specification carried an output electric power of 3–50 kW for charging battery electric vehicles using single-phase (230V) or three-phase (400V) alternating current (AC), with a typical maximum of 32 A 7.2 kW using single-phase AC and 22 kW with three-phase AC ...
But these charger types have been rarely deployed. Cost and thermal issues limit how much power the rectifier can handle, so beyond approximately 240 V AC and 75 A it is better for an external charging station to deliver DC directly to the battery. For faster charging, dedicated DC chargers can be built in permanent locations and provided with ...
Cars with battery voltages higher than the charger's voltage rating will not be able to charge at all (e.g. chargers with the minimum GB/T voltage of 750V will not be able to charge a 800V battery), though some such as the Hyundai E-GMP and Porsche Taycan can still use lower voltage chargers through the use of a boost converter.
