警告

Only technicians who have been trained in High Voltage Awareness and have completed all required certification courses (if applicable) are permitted to perform this procedure. Proper personal protective equipment (PPE) and insulating HV gloves with a minimum rating of class 0 (1000V) must be worn at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness Care Points for additional safety information.

拆卸

  1. 拆卸高压电池快充触点开关。请参阅Contactor - Fast Charge - HV Battery (Remove and Replace)
  2. 松开将交流输入端子盖板固定到负极和正极环形端子上的卡子,然后拆下盖板。
  3. 拆卸并弃置将负极和正极环形端子固定到母排的螺栓。

    警告
    此盖板为一次性用品,卡子十分脆弱,极易损坏。

安装

  1. 对 Hioki 电阻表执行零点调节,以便稍后在此程序中测量电阻。请参阅Resistance Meter (Zero Adjust)
  2. 使用异丙醇 (IPA) 湿巾清理正极环形端子与正极母排、负极环形端子与负极母排之间的接合面。
  3. 将高压电池快充触点开关盖板安装到高压电池快充触点开关上,然后紧固将盖板固定到触点开关的卡子(8 个)。
  4. 安装新螺栓,将正极和负极环形端子固定到母排上,紧固后,使用油性记号笔标记螺栓。
    4.4 Nm (3.2 lbs-ft)
  5. 使用 Hioki 电阻测试器测量正极环形端子的铜质部分与固定该端子的母排之间的电阻。
