1. Safety precaution for handling high voltage
i-MiEV uses two types of batteries. One is a 12V battery that is the same as the 12V battery used in
vehicles powered by internal combustion engines. The other is a high voltage maximum 370V (*1)
lithium-ion battery (Main drive lithium-ion battery). The Main drive lithium-ion battery provides high
voltage current to the high voltage components shown on page 2. Before rescue work can begin, it is
necessary to ensure “isolation” and “cut off” from the high voltage circuit in order to prevent the risk of
electric shock before handling the vehicle.
*1: Main drive lithium-ion battery specification is “16kWh lithium-ion, 330V”. Main drive lithium-ion battery
maximum voltage capacity is 370V when the Main drive lithium-ion battery is being charged.
(1) Design features of high voltage components
1) The high voltage circuit is insulated from the vehicle body.
2) All high voltage components are covered by cases and covers. These cases and covers are
insulated from the high voltage circuits inside.
3) High voltage wiring cables can be distinguished from normal wiring harness by their
orange-colored insulation.
Before handling the vehicle after an accident, and in order to reduce the risk of electric shock,
you must check to determine if any high voltage components have been damaged.
(2) Shutting off high voltage components
The high voltage circuits can be shut off by the following procedures:
1) Turn off the Electric Motor Switch (Ignition switch).
2) Disconnect the 12V battery or remove the power control unit fuse in the fuse box under the front
hood.
3) Remove the Service Plug.
Detailed procedures for shutting off the high voltage circuits are provided later in this manual.
Be advised that this vehicle is also equipped with sensors that are designed to shut down the high
voltage circuits in the event of moderate to severe impacts.
WARNING:
Always handle the vehicle in accordance with the instructions provided throughout this manual to
reduce the risk of injury from electric shock.
