 Any of the battery block voltages becomes less than 2.0 V (open circuit). (1 trip detection)

  • Battery smart unit

  • HV battery
P308A-123 All of the battery block voltages become less than 2.0 V (open circuit). (1 trip detection)

Tech Tips

Values below 2.0 V may not be indicated in the data list due to the substitution of a fail-safe value.

CAUTION / NOTICE / HINT

CAUTION:


  • Before inspecting the high-voltage system, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

  • After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

Tech Tips

Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
