Description
Technical Field
The invention relates to the field of charging, in particular to a charging control method, a charging control device, a storage medium and a processor.
Background
The lithium battery has the advantages of large energy density, long cycle life, wide working temperature range and the like, and is widely applied to the field of electric automobiles. Meanwhile, the safety and reliability of the lithium battery in the operation of the electric vehicle are also widely concerned, and the related research aiming at the health management and the service life evaluation of the lithium battery becomes a hot topic in the industry.
The traditional BMS is used as a bridge between a battery pack and a charging facility, integrates the functions of real-time battery data monitoring, health index estimation and real-time communication, and ensures the safe operation of the battery in real time. In the existing research, some researchers adopt the MCU as the central controller of the BMS, the stability and the reliability of the data acquisition of the system CAN not be ensured, and some researchers also adopt the DSP to replace the MCU as the central controller, so that the data processing capability is improved, and the CAN bus communication is adopted among the modules, so that the system realizes higher estimation precision and effectively improves the service efficiency of the battery.
In the above two methods, the information acquisition module and the parameter estimation module are both built in the BMS, which leads to the following problems: on the one hand, BMS is subject to dual limitations of equipment volume and cost; on the other hand, the distribution environment of the batteries in the electric automobile is very complex, and the batteries work under high-voltage and high-power conditions, so that the requirements on EMI/EMC are very high. This results in the BMS having to compromise the performance of each module, resulting in poor parameter estimation accuracy and inaccurate battery state estimation. Meanwhile, since the BMS completely controls the charging of the battery, the charging facility as an energy provider is in a passive state, and in the charging process, once the BMS malfunctions to cause communication interruption, the charging facility continues to charge the battery following the BMS output command before the malfunction, thereby causing the battery malfunction.
In view of the above problem that the charging process cannot be effectively controlled, no effective solution is proposed at present.
