WARNING: This page is about a different car, the 2024 Lexus TX 550h+. However, it is still accessible from the selected car via links, so may be relevant.
The CHRs (Charge Relays) are the relays that connect or disconnect the high-voltage system in accordance with commands from the Battery ECU assembly.
There are 3 CHRs and 1 system main resistor. CHRB, CHRP, CHRG and the system main resistor are located in the No. 2 traction battery device box assembly.
To connect to the high voltage power system, the vehicle will first turn on CHRP and CHRB to charge the vehicle through the system main resistor. Then, CHRP will be turned off after CHRG is turned on. To shut off the high voltage power system, CHRB and CHRG are turned off.
