At a charging station on a test site of a customer in Germany, a short-circuit occurred with a HUBER+SUHNER cooled high-power charging cable. Nobody was injured in this incident. The short-circuit occurred in the plug. The cooling circuit with the synthetic, non-conductive coolant can be ruled out as the cause. The product in question is a first-generation prototype.
Safety in the application of the products has the highest priority for HUBER+SUHNER. Although the products supplied comply with the required standards, HUBER+SUHNER checks the exact operating conditions of the high-power charging systems together with customers. With that the company wants to ensure that the further developed series products fully meet the requirements.
As a precautionary measure, HUBER+SUHNER has recommended its customers to suspend the operation of all charging stations with the high-power charging system until the tests have been completed.
The affected prototype was already delivered in the summer of 2017. The series products differ from the first prototypes by, among other things, increased sealing.
HUBER+SUHNER will provide further information as soon as new findings become available.
