LI-ION BATTERY HEATER : Disassembly and Assembly
INFOID:0000000010121181
DANGER:
Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of
electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are
handled incorrectly. Be sure to follow the correct work procedures when performing inspection and
maintenance.
WARNING:
• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-
ing inspection or maintenance of high voltage system harnesses and parts.
• To prevent the removed service plug from being connected by mistake during the procedure, always
carry it in your pocket or put it in the tool box.
• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses
before beginning work on the high voltage system.
• Refer to
EVB-7, "High Voltage Precautions"
.
• To prevent electric shock hazards, ignition, and damage to parts, always remove Li-ion battery con-
troller before disassembling battery pack.
CAUTION:
There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the
service plug is removed. Therefore do not change the vehicle to READY status unless instructed to do
so in the Service Manual.
WORK ENVIRONMENT FOR DISASSEMBLY OF LI-ION BATTERY
1. Must be an indoor environment.
• The work environment must be able to be isolated from the outside by shutters or other means to pre-
vent the intrusion of rain, snow, sand, and other substances.
• The environment must prevent the entry of sweat during work, and also prevent condensation from
occurring as a result of high temperature and humidity.
2. No entry of foreign materials.
• In addition to being indoors, the environment must not permit the entry during disassembly work of
metal powders, oil, or foreign substances resulting from causes such as servicing of other vehicles.
• If there is any risk of the above, use a plastic curtain or other means to block off the work area, or take
other necessary steps.
3. The floor must be dry.
• The floor must not become wet as a result of causes such as vehicles entering when it is raining or
snowing.
4. Work space
• Space approximately the size of one vehicle must be secured as the disassembly space.
• A sign indicating that disassembly is in progress or other measures must be taken so that persons other
than the workers do not enter the work space.
5. Standard fire fighting equipment
• Always place a standard fire fighting equipment in the disassembly work area.
• Depending on type of fire (vehicle or battery) use standard fire fighting equipment (water or extin-
guisher).
