Abstract

The invention relates to a relay service life obtaining method and device, a storage medium, electronic equipment and a vehicle. The remaining service life of a high-voltage relay can be accurately estimated. The invention discloses a high-voltage relay life obtaining method. The method comprises the steps of obtaining current life loss of a high-voltage relay, wherein the current life loss comprises first life loss caused by current closing and opening times; wherein the second service life loss is caused by the voltage difference between the two ends of the high-voltage relay in the currentclosing period, the third service life loss is caused by transient current in the current opening period, and the fourth service life loss is caused by electrifying current and temperature in the current charging and discharging accumulation time in the whole vehicle using process; and normalizing the obtained current life loss to obtain the residual service life of the high-voltage relay.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular, to a method, device, storage medium, electronic equipment, and vehicle for obtaining the service life of a relay. Background technique [0002] High-voltage relays are important electrical appliances in vehicles, however, there is no technology to estimate the remaining service life of high-voltage relays. Contents of the invention [0003] The purpose of the present disclosure is to provide a method, device, storage medium, electronic equipment and vehicle for obtaining the service life of a relay, which can accurately estimate the remaining service life of a high-voltage relay. [0004] According to the first embodiment of the present disclosure, there is provided a method for acquiring the life of a high-voltage relay, including: acquiring the current life loss of the high-voltage relay, wherein the current life loss includes the first life loss caused by the ...
