EV Charging Stations

With the drive to reduce dependency on fossil fuels, electric and hybrid vehicles are becoming more popular. To support this trend, a network of EV charging stations has to be established. Because these are connected to the normal power grid, they are subjected to testing rules following the International Electro technical Committee (IEC), which includes EFT/Burst, surge and dips testing. The charging stations have AC inputs and DC outputs, which both must be tested.

EMCP test solutions, specialized Coupling Decoupling Networks (CDN) and accessories help the operator to easily perform these tests with high reliability and flexibility


ON-Board Charging

EMCP offers for Level 1 and Level 2 AC on-board charger a broad range of test solutions and accessories specialized on the testing of charging Rechargeable Electrical Energy Storage System (REESS) coupled to the Power Grid.

OFF-Board Charging

EMCP offers generators along with a wide range of specialized CDNs and over-current protections operating up to 1500 Vdc and 200A for dedicated Level 1 to Level 4 off-board charger which are installed in residential as well as in non-residential environments.

Wireless Power Transfer Charging

Wireless power transmission (WPT) is becoming more and more popular, especially in the EV automotive sector.

EMCP also offers therefor test solutions dedicated to the testing of WPT charging stations. Our equipment covers supply voltages up to 690Vac and 1500Vdc.
