Battery pre-charge system failure
When the pre-charge circuit fails to close properly (the resistor is open, or the K1 relay is not closing), the greater inrush current will occur at the end of the pre-charge cycle, damaging the contactors, the capacitor, and the main fuse. Therefore, the reliable operation of the pre-charge circuit is paramount, or its operation. When you turn on the ignition, the hybrid battery connects to the rest of the hybrid circuit via the contactor. A second before this connection is made, the voltage of the various hybrid.

Why is my pre-charge resistor failing?
The pre-charge resistor failing due to over-heating then needs to be at least considered. In a battery the contactors are a switch that can be operated by the control system. They are essentially a relay. These contactors are designed to be able to break (switch off) the circuit under full load (maximum current and at maximum system voltage).
What happens if a pre-charge circuit fails?
In hybrid or electric vehicles, the pre-charge circuit is used whenever the car is turned on. When the pre-charge circuit fails to close properly (the resistor is open, or the K1 relay is not closing), the greater inrush current will occur at the end of the pre-charge cycle, damaging the contactors, the capacitor, and the main fuse.
What is a precharge fault code?
Precharge fault codes can be very tricky to diagnose and troubleshoot. A fault in any of the hybrid components on the hybrid system may cause a long pre-charge time in the BMS (Battery Management System).
What causes precharge failure in a high-voltage system?
Precharge failure in a high-voltage system can result from several factors, which include: Damaged Precharge Resistor: If the precharge resistor is damaged or its value has deviated from the intended value, it can lead to either excessively rapid or slow precharging.
What causes a long pre-charge time?
A fault in any of the hybrid components on the hybrid system may cause a long pre-charge time in the BMS (Battery Management System). The most common problem that causes a pre-charge time that is too long is a faulty hybrid battery, with the second most likely cause being a problem with the DC/DC converter.
