Title:
A SYSTEM PROTECTION CONTROL METHOD FOR THE HYBRID POWER AUTOMOBILES
Document Type and Number:
WIPO Patent Application WO/2009/092218
Kind Code:
A1
Abstract:
The invention provides a system protection control method for the hybrid power
automobiles. The method includes: determining if the high voltage battery is
over-charged, if the high voltage battery is over-discharged, if the high voltage
battery, the inverter or the motor/generator is over-heated, and if the motor/generator
is over-speed; when any one or multiple of the signals of the motor/generator
off-work request, the high voltage battery off-work request, and the DC-DC inverter
off-work request is determined to be activated according to the above four determinations,
activating the corresponding off-work request signal, and shutting down the
corresponding elements. In this method, multiple off-work request signals
are controlled according to the charge state SOC, the balance point of the SOC
work field of the high voltage battery, the state of generator and the maximum
charge power , the temperature of the battery, the temperature of the motor and
the temperature of the inverter et al. recommended by the battery controller.
The protection of avoiding over-charge, over-discharge, over-heat of the battery
and the motor torque protection of avoiding over-speed will be realized.
