Embodiment

[0020] Such as figure 1 As shown, an intelligent vehicle power management module includes a power output unit, a microcontroller 1, a switch input unit 3, a sensor input unit 4 and a CAN bus interface 5, wherein the power output unit includes two power output circuits, respectively 40A power output circuit 21, which is provided with 8 power output terminals, and 6A power output circuit 22, which is also provided with 8 power output terminals, and the power input terminals of these two power output circuits are connected to the storage battery of the car 6. The power output terminal is connected to the electrical equipment of the corresponding voltage, and the signal input terminal thereof is connected to the microcontroller 1 . Since the power output unit uses power semiconductor devices such as MOSFET and IGBT instead of the traditional relay, its output can be controlled by the control signal of the microcontroller 1, and its reliability is obviously higher than that of the ...

The signal input end of the microcontroller is connected with a control switch, a sensor and a CAN bus of the automobile through the switch input unit, the sensor input unit and the CAN bus interface respectively. Compared with the prior art, the intelligent automobile power supply management module has the advantages of being high in reliability, flexible to control and the like.

Description

technical field [0001] The invention relates to an automobile power supply system, in particular to an intelligent automobile power supply management module. Background technique [0002] With the development of technology and the improvement of people's living standards, the requirements for vehicle safety and comfort are getting higher and higher, accompanied by the increase of a large number of electrical equipment and various high-end configurations. [0003] According to statistics, at present, one out of every five cars that break down is caused by the power supply system. At present, automobiles have been developing towards safety and comfort, and there are more and more electrical appliances. Therefore, the traditional power management system using relays and fuses cannot realize intelligent control due to its single control method, and failures The rate is relatively high, which can no longer meet the current development requirements. Contents of the invention ...
