BATTERY CONSTRUCTION [LF]
• Air that passes through the battery duct when the
vehicle is moving is used to cool the battery,
preventing battery degradation from the heat
created through chemical reaction, improving
reliability.
End Of Sie
GENERATOR CONSTRUCTION [LF]
• With the elimination of the voltage regulator, generator control is carried out by the PCM. Excitation current in
the field coil is increased or decreased by the duty signal from the PCM sent to the power transistor built into
the generator.
• Two delta connection type stator coils have been adopted.
• A generator duct and a generator heat insulator made of plastic have been adopted to protect the generator
from the exhaust manifold heat.
