Abstract: PURPOSE: A protecting circuit device for a motor control unit of an electric vehicle is provided to protect the motor control unit in hardware by restricting the current flowing into the control unit by using a PTC(Positive Temperature Constant) resistor. CONSTITUTION: A protecting circuit device for a motor control unit of an electric vehicle is implemented between a main battery(21) and the motor control unit(22) and is driven by a free charge relay(23) and a main relay(24,25). The protecting circuit lowers a voltage of a DC link capacitor(26) of the motor control unit to a voltage level of the main battery. The protecting circuit further includes a temperature-variable resistor(31) on one side of the free charge relay. The temperature-variable resistor restricts the amount of current flowing to the motor control unit when the DC link capacitor is short-circuited.

Abstract: A method for diagnosing a defect of a DC-DC converter of an electric vehicle is provided to lengthen durability of the DC-DC converter and an auxiliary battery in a hybrid/fuel cell vehicle by diagnosing rapidly the defect of the DC-DC converter. A low-voltage DC-DC converter outputs a voltage according to a voltage command received from an external controller and monitors simultaneously an output voltage. The voltage command and the real output voltage are compared with each other in order to diagnose a defective state of a DC-DC converter. When a difference between the voltage command and the real output voltage exceeds a reference voltage and the exceeding time of the reference voltage is maintain during a constant period, the defective state is diagnosed. The low-voltage DC-DC converter generates a defective diagnosis code and turns on an alarm lamp.

Abstract: A battery protection circuit of a hybrid motor controller and a protecting method thereof are provided to reduce a code quantity and a work load by acquiring various values by substituting a function value through a PI(Proportional and Integral) control loop process using a loss function. A battery protection circuit of a hybrid motor controller includes a loss calculation unit(314), a multiplier(310), an adder(318), PI controllers(324a,324b), and a limiter(302). The loss calculation unit(314) receives a current command, a loss function, and a rotation number of a motor. The loss calculation unit(314) calculates a loss of an inverter and a motor. The multiplier(310) calculates mechanical power by multiplying the rotation number by a torque command inputted in an HCU(Hybrid Control Unit). The adder(318) calculates electric power by adding the mechanical power calculated in the multiplier(310) to the loss calculated in the loss calculation unit(314). The PI controllers(324a,324b) calculate a driving torque limit value and a generation torque limit value based on a value that battery power fed back from the adder(318) is subtracted from a power limit value and a charging power limit value outputted from a BMS(Battery Management System) through PI control. The limiter(302) limits a torque command through the driving torque limitation value and the generation torque limitation value.
