Plug-in Charging Safety (2010 Model)
The HV battery assembly can be charged using power from an external power
outlet. AC power is supplied to the charge inlet by the charge cable assembly
and sent to the charger assembly. There are basically 2 circuits in the charger
assembly: One is an AC/DC converter circuit and the other is a booster circuit
used to boost the charger input voltage to 346 Volts. DC power from the
charger assembly is used to charge the HV battery assembly. To provide
information about charging or remote air conditioning status, the hybrid vehicle
computer illuminates the charge indicator on the instrument panel pad during
charging and when the remote air conditioning system is on.
When remote air conditioning system operation or charging completes, relays
are opened to stop charging system high voltage power flow.
The following systems are intended to help keep vehicle occupants and
emergency responders safe from high voltage electricity:
Plug-in Charging System Safety System
• The hybrid vehicle computer monitors the charging system based on
information from various sensors. If the hybrid vehicle computer detects a
malfunction, charging is stopped, relays are opened, and the charge
indicator flashes to indicate the presence of the malfunction.
WARNING:
The high voltage system, including the charging system, may remain
powered for up to 10 minutes after the vehicle is shut off, disabled, or
charging stops. To prevent serious injury or death from severe burns or
electric shock, avoid touching, cutting, or breaching any orange high
voltage power cable or high voltage component.
