Power supply control system and control method of lithium capacitor

Abstract

The invention discloses a power supply control system and control method of a lithium capacitor, and the system comprises a main controller, an external controller, a high-voltage controller, a motor, a BDU, a charger, a slave controller II, a cell controller II, a cell II, a switch, a cell I, a cell controller I, a slave controller I, an external interface, and an external instrument. The battery cell controller I and the battery cell controller II are directly connected with the battery cell I and the battery cell II in series, and a switch is arranged between the battery cell controller I and the battery cell controller II, so that the discharge current of the single battery cell I or the single battery cell II can be controlled and monitored in real time; therefore, the data signals are transmitted to the slave controller I and the slave controller II for screening and signal processing. The main controller completes data transmission by adopting an internal CAN protocol, each device is provided with an independent controller to complete data acquisition, screening and processing, and the data is transmitted to the main controller through the internal CAN protocol for unified command.

Description

technical field [0001] The invention belongs to the technical field of power control systems, and in particular relates to a power control system and a control method for lithium capacitors. Background technique [0002] With the continuous development of technology and the continuous enhancement of people's awareness of environmental protection, the application range of lithium capacitors continues to expand, and it has been paid attention to in the fields of night lighting, storage and transportation, logistics and transportation. The discharge operation of the corresponding power can be carried out to complete the work of the designated equipment. The traditional lead-acid storage battery has a small energy storage, a large volume and a bulky overall, and a short service life. The electrolyte is corrosive to a certain extent. Through the control process of the system Among them, the charging and discharging speed of the battery is slow, it cannot respond quickly to the co...

[0002] With the continuous development of technology and the continuous enhancement of people's awareness of environmental protection, the application range of lithium capacitors continues to expand, and it has been paid attention to in the fields of night lighting, storage and transportation, logistics and transportation. The discharge operation of the corresponding power can be carried out to complete the work of the designated equipment. The traditional lead-acid storage battery has a small energy storage, a large volume and a bulky overall, and a short service life. The electrolyte is corrosive to a certain extent. Through the control process of the system Among them, the charging and discharging speed of the battery is slow, it cannot respond quickly to the command signal, and the discharge speed cannot meet the requirements of the equipment; the traditional power control system performs unified control on multiple battery packs, and needs to When cutting off, the controller responds and cuts off all battery packs. At this time, the condition of the equipment in operation is unknown, and it is easy to cause danger by directly cutting off the power
