Abstract

The invention provides a vehicle-mounted smart power grid. The vehicle-mounted smart power grid comprises a car power source, a smart power grid control unit and a car power supply network, wherein the car power source is used for providing electric energy, the smart power grid control unit is connected with the car power source, and is used for carrying out controller voltage conversion, battery parameter monitoring, battery charge state estimation and power supply overcurrent protection, and the car power supply network is used for supplying power to electric appliances of a whole car. The vehicle-mounted smart power grid has the advantages of being independent of a car electric appliance electronic control system and a communication network, achieving real separation between electricity and control, reducing electromagnetic interference of a power supply line on control signals and communication signals, providing a safe stable power supply environment for electric appliance electronic control and a car communication system, providing classified power supply sources for traditional power loading and electric control units of the electric appliances of the whole car, improving stability and reliability of a controller power source, carrying out real-time monitoring and electricity loss protection on a storage battery, carrying out power supply monitoring and overcurrent protection on subnets, achieving monitoring and protection on power supply of the whole car, and ensuring electrical safety of the car.

Description

technical field [0001] The invention relates to the technical field of automobile electrical control, in particular to a vehicle-mounted smart grid. Background technique [0002] With the increasing number of electrical appliances used in modern automobiles, the power supply of electrical appliances used in vehicles is becoming more and more complicated. With the development of vehicle bus communication technology, especially CAN bus and LIN bus, more and more automotive electrical appliances begin to use The functional controller controls the electrical appliances. Therefore, various electrical appliances and controllers form power supply circuits, which leads to the chaos of the entire vehicle electrical system and brings great hidden dangers to the safety of automotive power supply. The complex electrical system also puts forward higher requirements on the safety of electricity use, that is, the ability of the automotive power supply to handle overcurrent and short circui...
