DRIVE BATTERY
The drive battery consists of lithium-ion battery
that is small and lightweight and also has a
high energy density. The motor (electric motor
unit) and the air conditioner system are
powered by the drive battery. The drive battery
is housed in the plastic case that has vibration-
resistant properties. The case is placed under
the centre console in the vehicle. The battery
has 6 of 12-cell modules in which 12 battery
cells are in series. In total, the 72 battery cells
are connected in series. The battery generates
a high voltage of 259 V (nominal value). The
maximum operating voltage 310 V may be
generated depending on the remaining
capacity of the battery.
SERVICE PLUG
The service plug is installed inside the rear of
the floor console in the vehicle. Remove the
service plug before performing the check and
the maintenance work on the high voltage
components to ensure the job safety, shutting
off the high voltage circuit.
