With the increasing battery capacity of electric vehicles aimed at delivering more driving range and reducing range anxiety, there is an obvious global demand emerging for DC fast-charging stations. Designs of ESVEs (Electric Vehicle Supply Equipment) are complicated by the industries' inability to standardize which is resulting in different charging interfaces and power levels depending on car type and location of charging stations. Current DC charging standards include CCS or NACS in Europe and North America, CHAdeMO in Japan, and GB/T in China. Each of these use different charging connectors and utilize different communication protocols.

Regarding the application of an Automatic Test System (ATS) for DC EVSE in End of Line (EOL) testing on the production line.Based on years of industry experience, Chroma has summarized several technical issues that production may encounter and provided recommended solutions. This article addresses the following 5 challenges of EOL testing of EVSE's. Click the link to learn more!
