Title:
POWER SOURCE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/138827
Kind Code:
A1
Abstract:
A power source control system (10) includes a control device (60) and a power source system which is to be controlled by the control device (60). The power source system includes a high voltage battery (12), an inverter (14), a DC/DC convertor (50), a low voltage battery (26), and components mounted on a control substrate (20) for controlling the inverter (14). The control device (60), in addition to ordinary DC/DC converter operation control, includes a control substrate temperature acquisition processing unit (62) which acquires a control substrate temperature from a temperature sensor (22) provided on the control substrate (20) and an output restriction processing unit (64) which restricts VDCDC to a value lower than a value for ordinary control when the acquired control substrate temperature is high. As the control substrate temperature, a value estimated from the temperature of a coolant or the like used for cooling an inverter housing (30) may be used.
