Method for estimating the usage time of at least one capacity for an on-board charger.

Abstract

The invention relates to a method for estimating the usage time of at least one capacity of a DCLINK module of an electronic device, said electronic device being adapted to charge a high-voltage battery of an electric vehicle, said device comprising a power factor correction circuit, a DC / DC converter, a cooling device comprising at least one channel adapted for the passage of a coolant, said device being adapted to cool at least one capacity of the DCLINK module using the coolant, the method comprising the following steps: a first step S1) consisting of performing a third step S3) as long as an exceedance of a first usage time of the electronic device (100) is not reached, and performing an eighth step S8 after the exceedance of the first usage time of the electronic device (100), a seventh step S7),consisting of calculating an actual usage time of at least one capacity (DCaprel) based on the average value (MTrelcap_M) and / or the average value (MIrelcap_M).
