The invention discloses a power management method and system for a vehicle-mounted storage battery, and relates to the technical field of automotive electronics, the provided power management method for the vehicle-mounted storage battery is applied to a processor, and the processor executes the following steps: controlling the storage battery to supply power to a vehicle load, obtaining the current temperature of the storage battery and the current use state of the vehicle load; obtaining the residual capacity Q of the storage battery according to the current temperature and the current use state, and displaying the residual capacity Q on a display device; and determining the depth of discharge (DOD) of the storage battery based on the obtained residual capacity Q so as to obtain the health condition of the storage battery. According to the power management method and system for the vehicle-mounted storage battery, the current battery performance of the storage battery can be accurately displayed, and the situation that the vehicle cannot be normally started due to excessive power consumption of the vehicle-mounted storage battery is prevented.
Description
technical field [0001] The present application relates to the technical field of automotive electronics, in particular to a power management method and system for a vehicle battery. Background technique [0002] With the rapid development of the economy, the on-board battery is an important power supply device of the vehicle, and its performance affects the normal state of the vehicle. The combination instrument on a traditional vehicle generally displays the terminal voltage of the battery, but the terminal voltage parameter cannot actually reflect the state of charge of the battery, causing the driver to fail to start the engine normally due to excessive battery power consumption. If the terminal voltage of the battery is used as a characterization parameter of battery performance on the livestock and poultry vehicle, then when the livestock and poultry vehicle cannot start normally, it will easily lead to the transportation risk of the poultry carried by the livestock and...
