Graphene heating convenient starting power supply

Abstract

The graphene heating convenient starting power supply comprises a box body, a battery pack and an electrical assembly, the box body comprises a plurality of side plates, a top plate, a bottom plate and a plurality of connecting pieces, one ends of the side plates are arranged on the edge of the bottom plate in a surrounding mode, the top plate is parallel to the bottom plate and detachably connected with the other ends of the side plates, and the connecting pieces are arranged at the corners of the side plates. The box body is used for connecting the two side plates, a partition plate is further arranged in the box body and connected with the side plates, the box body is divided into a first cavity and a second cavity, the first cavity and the second cavity are used for installing an electrical assembly and a battery pack respectively, the battery pack comprises a plurality of square batteries and graphene sheets, the graphene sheets are arranged between the square batteries stacked up and down, and the electrical assembly comprises a BMS plate. The BMS board is electrically connected with the temperature sensors, the energy storage capacitor and the square battery, and the energy storage capacitor is electrically connected with the graphene sheet. The energy storage capacitor is used for supplying power to the graphene sheet and heating the square battery, so that the power supply can be quickly started in a low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of energy storage devices, in particular to a convenient start-up power supply for graphene heating. Background technique [0002] The starting power supply device, that is, the charger, can be used to start the starting system of cars, trucks, airplanes, ships, etc. with a voltage of 12 volts or 24 volts. It realizes the optimized Wsa+Pulse charging characteristic curve through microcomputer control technology, and the charging current varies with The charging voltage of the battery automatically decreases when the charging voltage increases; combined with the pulse charging method at the end of the charging, the charging effect is more ideal. Especially when charging aircraft special equipment, the voltage is required to be kept at 28V+ / -1V, and the voltage fluctuation control needs to be very accurate. High current (1000A) discharge requires high battery and control requirements, which are all used by BMS...
