Customized ZETTLER AZEV132 Relay for E-mobility Charging Applications According to IEC62752 Mode 2

PublishTime： 2021-01-02 Article Source：ZETTLER

Due to the growing market for electric vehicles, the demand for charging infrastructure products is increasing rapidly. During the initial phases of the e-mobility rollout, mostly purely functional Mode 2 charging cables in accordance with IEC62752 were required. Today, manufacturers are also paying more and more attention to an attractive design with a high recognition value. There is also a strong focus on reducing the size of such devices.

A market leader in the field of high-end charging infrastructure approached ZETTLER because they desired a relay according to IEC62752 for its new generation of mode 2 charging cables with additional customized design features. Based on the experience and variety of reliable ZETTLER relays, a customized version was built according to the customer’s needs. The customer is highly satisfied with the resulting individualized relay solution, packaged in a tailor-made housing and printed in its own design.

ZETTLER's AZEV132 relay is a 1-pole power PCB relay, initially developed specifically for use in accordance with IEC62752 and, more importantly, to meet the exceedingly stringent short-circuit withstand-current requirements of this standard. These relays also have a monitoring contact to allow detection of any possible welding issues with the main contacts. The relays are approved at UL, CUR and TüV with ratings of up to 40A with 6k switching cycles (32A with 100k switching cycles) for the normally open load contact and 10mA at 12VDC with 50k switching cycles for the normally closed monitoring contact.

A new version with switching capability of up to 50A, ZETTLERs AZEV140, is planned for series production in 2021.
