The development of electric vehicles (EVs) drives the growing demand for charging stations (EVSE). As different EVs require the use of different charging methods, EVSE products need to support not only AC and DC charging modes, but also safe, reliable, and fast charging, as well as accurate measurement and precise control of the charging capacity. Chroma has been deeply involved in the field of EV testing for many years, providing a variety of complete EVSE test solutions. Now, Chroma proudly presents the all-new 61800-100 Regenerative Grid Simulator, a 105kVA high-power AC power supply solution.
Chroma 61800-100 has a maximum output voltage range of 500VLN and low voltage distortion in compliance with the relevant regulations for EVSE (such as IEC 61851, SAE J1772, and CHAdeMO) as well as for electrical energy testing of AC power supplies (such as IEC 62052 and 62053). The energy recovery function is fully applicable to EVSE test applications, including V2G (Vehicle to Grid) and V2L (Vehicle to Load) functionality. An energy-saving choice, Chroma 61800-100 can directly convert the energy generated by the EVSE under test back to the grid, without transforming that energy into heat.
The AC Source mode meets EVSE's V2G functional test requirements, whereas the AC Load mode offers rectified CC, rectified CP, phase lead, phase lag, and CR functions to fulfill EVSE's V2L functional test requirements. In addition, the standards regarding the immunity of the EVSE AC input terminal (IEC 61000-4-11 regulations on voltage dips, short interruptions, and voltage variations) can also be satisfied by using the 61800-100’s advanced voltage waveform editing function. The grid simulator provides customers with a variety of test applications and ensures that product verification meets the relevant regulatory standards.
Many manufacturers and certification bodies have already started using Chroma 61800-100 for EVSE related testing and certification. Most recently, an oversea certification laboratory adopted five 61800-100 units in parallel to achieve a maximum output power of 525kVA, so meeting the requirements for AC and DC EVSE testing on a variety of power levels.
