Abstract
Provided is an electric battery charging system, including a connector including a thermistor element configured to change a resistance value according to a temperature, a micro control unit (MCU) configured to receive a voltage varying depending on whether the connector is connected, and receive a voltage varying according to the resistance value of the thermistor element, and a vehicle charging management system (VCMS) configured to determine whether to discharge a battery based on whether the connector is connected and a temperature of the connector.
Claims20
An electric battery charging system, comprising:
- a connector comprising a thermistor element configured to change a resistance value according to a temperature;
- a micro control unit (MCU) configured to receive a voltage varying depending on whether the connector is connected, and receive a voltage varying according to the resistance value of the thermistor element;
- and
- a vehicle charging management system (VCMS) configured to determine whether to discharge a battery based on whether the connector is connected and a temperature of the connector,
- wherein the electric battery charging system further comprises a proximity detection (PD) sensing circuit, when a PD voltage detected by the PD sensing circuit is less than or equal to a threshold voltage value, the micro control unit (MCU) determines that the connector is connected to a vehicle and a switch indicating a power button is closed.
A vehicle, comprising:
- an MCU configured to receive a voltage varying depending on whether a connector is connected, and
- comprise a thermistor element that changes a resistance value according to a temperature and receive a voltage varying according to the resistance value of the thermistor element;
