Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description of the BMS system of the present invention is made in detail with reference to the accompanying drawings.
As shown in fig. 1, the BMS system of the present invention comprises:
the input module 1 is used for being connected with an external circuit and receiving current input;
the detection module 2 is used for detecting the current state and judging whether the current state meets the power supply state or the communication state;
the power supply module 3 is used for connecting the input module 1 to the power supply module 3 when the current meets the power supply state;
and the communication module 4, when the current satisfies the communication state, the input module 1 is connected to the communication module 4.
The power supply module 3 and the communication module 4 are both electrically connected with a vehicle-mounted MCU serving as the control module 6, namely connected to an input port of the MCU. The power supply module is used for supplying power to the control module 6. And the communication module 4 is used for inputting control signals to the control module 6 so as to control the control module 6. Like this BMS system, communication and power supply front end multiplex, adopt an input module 1 can, after the current signal got into BMS system, according to the judged result of detection module 2, in the input module 1 input power module 3 or communication module 4. When current is input into the power supply module 3, the control module 6 operates normally; when current is input to the communication module 4, the control module 6 is regulated by signal control.
In order to solve the power supply problem of the BMS system in the communication state, the BMS system further includes an energy storage module 5, which is a capacitor, electrically connected to the power supply module 3, and the energy storage module 5 supplies power instead of the power supply module 3 when the current satisfies the power supply state.
The current state comprises a voltage. Correspondingly, the power supply state includes that the current is high level. The communication module 4 comprises a low level of current. Thus, the power supply state and the communication state are switched according to the high and low levels.
The BMS system further includes:
the temperature detection module 7 is electrically connected with the control module 6 and is used for detecting the temperature of the battery;
and the balancing module 8 is electrically connected with the control module 6 and is used for balancing the voltage of each battery.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
