Pre-Charge Relay

WARNING: This page is about a different variant/trim than selected.

The pre-charge relay is contained in the battery junction box, and is controlled by HPCM. When supply of high-voltage power is needed, HPCM activates the pre-charge relay and power is supplied via the charging resistor, preventing the sudden application of high-voltage.
