Delta's automated testing solution improves development efficiency and product quality of EV chargers

EV charger equipment is characterized by precision and complexity. Traditional testing equipment has no built-in communication protocols, hence cannot enable communication between electric vehicles and chargers. It only tests power-related items, but not the performance of a charger while charging an EV. Nor can it simulate all possible usage scenarios, thereby creating testing gaps and underlying concerns for future products.

To test Delta’s own EV charger products, the manufacturing and testing equipment department specially developed an automated testing solution for chargers that is compatible with mainstream CHAdeMO, ISO15118, and DIN70121 communication protocols and capable of detecting whether a charger can communicate with electric vehicles on the market. Once communication is established, system functions or components such as panels and buttons can be further tested. It can even simulate various usage scenarios (such as simultaneously charging by using multiple connectors) to verify if chargers are able to maintain high efficiency under any usage conditions. Be it an AC or DC charger, the solution can thoroughly test out compatibility with various communication protocols and charging functions of chargers.
 
The system is equipped with Smart 1 integrated software testing platform that includes complete testing items. Once specific items are selected, a testing will be automatically activated, which considerably reducing the testing time in the past from one or two weeks to a few hours. Delta's automated testing solution significantly enhances the test efficiency of chargers during R&D and shortens market response time. Fast, plentiful, and accurate testing takes Delta's product quality of chargers and related development speed to the next level.
 
In addition to serving internal customers, the automatic testing equipment will also be promoted to a broad array of global manufacturers of electric vehicles and charging equipment.
