Abstract

A DC-to-DC converting apparatus with communication function for a vehicle is applied to an electric vehicle or a hybrid vehicle. The electric vehicle or the hybrid vehicle includes a vehicle control system. The DC-to-DC converting apparatus with communication function for a vehicle includes a DC-to-DC converter, a control circuit is electrically connected to the DC-to-DC converter, and a system communication interface is electrically connected to the control circuit and the vehicle control system. The working status of the DC-to-DC converter is detected by the control circuit and is informed to the vehicle control system through the system communication interface. The control circuit is controlled to control the DC-to-DC converter by the vehicle control system through the system communication interface.

Claims

1. A DC-to-DC converting apparatus with communication function for a vehicle applied to an electric vehicle or a hybrid vehicle, the electric vehicle or the hybrid vehicle comprising a vehicle control system, and the DC-to-DC converting apparatus comprising:

a DC-to-DC converter;

a control circuit electrically connected to the DC-to-DC converter; and

a system communication interface electrically connected to the control circuit and the vehicle control system;

wherein a working status of the DC-to-DC converter is detected by the control circuit and is informed to the vehicle control system through the system communication interface; and

the control circuit is controlled to control the DC-to-DC converter by the vehicle control system through the system communication interface.

2. The DC-to-DC converting apparatus in claim 1, further comprising an EMI/EMC filter electrically connected to the DC-to-DC converter.

3. The DC-to-DC converting apparatus in claim 1, wherein the system communication interface is an inter-integrated circuit (I2C), a PM bus, a local interconnect network (LIN), or a controller area network (CAN).

4. The DC-to-DC converting apparatus in claim 1, further comprising a component temperature sensor electrically connected to the control circuit to measure temperature of components of the DC-to-DC converting apparatus.

5. The DC-to-DC converting apparatus in claim 1, further comprising an ambient temperature sensor electrically connected to the control circuit to measure ambient temperature of the DC-to-DC converting apparatus.

6. The DC-to-DC converting apparatus in claim 1, wherein the vehicle control system is electrically connected to a display, and the working status of the DC-to-DC converter detected by the control circuit is shown on the display.
