  • Driver circuit for an electric vehicle and a diagnostic method for determining when a voltage driver is shorted to a ground voltage
    Patent number: 9024468
    Abstract: A driver circuit and a diagnostic method are provided. The driver circuit includes a first voltage driver, a second voltage driver, an electrical current sensor, and a microprocessor. The microprocessor iteratively measures voltages on first and second sides of a contact to obtain a first plurality of voltage values and a second plurality of voltage values. The microprocessor determines first and second filtered voltage values based on the first and second plurality of voltage values, respectively. The microprocessor determines a difference value based on the first and second filtered voltage values. The microprocessor de-energizes a contactor coil if a first signal from an electrical current sensor is received, and the difference value is greater than a predetermined threshold value.

  • Driver circuit for an electric vehicle and a diagnostic method for determining when an electrical short circuit to a ground voltage is present between a contactor coil and a voltage driver
    Patent number: 8994210
    Abstract: A driver circuit and a diagnostic method are provided. The driver circuit includes a first voltage driver, a second voltage driver, and a microprocessor. The microprocessor iteratively measures voltages on first and second sides of a contact to obtain a first plurality of voltage values and a second plurality of voltage values. The microprocessor determines first and second filtered voltage values based on the first and second plurality of voltage values, respectively. The microprocessor de-energizes a contactor coil if both the first filtered voltage value is substantially equal to the second filtered voltage value, and a first filtered current value is less than a threshold current value.
