The invention discloses a method for distributing power of a vehicle-mounted hybrid power supply on the basis of multiple inference rules. The method for distributing the power of the vehicle-mountedhybrid power supply on the basis of the multiple inference rules comprises the following steps: acquiring the charge states of a storage battery and a super capacitor in real time, and the required power of the load of an electric automobile in a running process; judging whether the charge states of the storage battery and the super capacitor are in a minimum state or not; if not, judging whetherthe charge states of the storage battery and the super capacitor are in a maximum state or not; if not, judging the running state of the electric automobile according to the acquired required power, determining the value range of a weighting factor according to the running state and the required power of the electric automobile and the charge states of the storage battery and the super capacitor,and optionally selecting the weighting factor meeting the required power of the electric automobile from the value range of the weighting factor; and determining powers respectively required to be provided by the storage battery and the super capacitor under the current running state according to the weighting factor to complete power distribution in the hybrid power supply, so that the hybrid power supply can simultaneously meet double requirements of the electric automobile on energy and power.
Description
Technical field [0001] The invention relates to the technical field of batteries, in particular to a vehicle-mounted composite power distribution method based on multiple inference rules. Background technique [0002] In recent years, with the continuous advancement of power electronic technology and microprocessor technology, the research and application of electric vehicles has increased. The power supply formed by a single energy storage device such as batteries, supercapacitors, flywheels, and solar cells can no longer satisfy electric vehicles. For the dual requirements of energy and power, combining multiple energy storage devices to form a composite power source is a feasible and universal solution. [0003] At present, battery-supercapacitor composite power supplies are favored by scholars at home and abroad. Among them, batteries are used to provide high energy density required by vehicles, and supercapacitors are used to provide high power density required by vehicles. H...
