The invention belongs to the technical field of lithium batteries, and particularly relates to a charging method and system for controlling a lithium battery through an intelligent protection plate. The method comprises: detecting whether a lithium battery pack is completely connected with a charging plug of a charger; making an intelligent protection plate and the charger carry out information confirmation mutually; and entering a charging stage, and adjusting the output current IOUT and the output voltage VOUT by the charger according to the state of the lithium battery pack. The system comprises a charger, a lithium battery pack, an intelligent protection plate, a cloud server / server, a monitoring platform and a user APP, wherein the intelligent protection plate is arranged in the lithium battery pack, the charger is connected with the lithium battery pack through a cable, the intelligent protection plate is in communication connection with the charger and the cloud server / server, and the cloud server / server is in communication connection with the monitoring platform and the user APP. According to the invention, real-time information interaction between the intelligent protection plate and the charger is realized, so that the charging safety problem of the lithium battery under different working conditions is solved.
Description
technical field [0001] The invention belongs to the technical field of lithium batteries, and in particular relates to a charging method and system for a lithium battery controlled by an intelligent protection board. Background technique [0002] With the country's emphasis on the environment, the development of lithium battery technology and the continuous reduction of costs, more and more fields are switching from lead-acid batteries to lithium-ion batteries. [0003] However, the application of lithium batteries is different from that of lead-acid batteries, and the charging current at different temperatures and voltages is different. However, the current protection board is used to protect the lithium battery. The protection parameters of this type of protection board are fixed and cannot be automatically adjusted according to the use environment and working conditions of the lithium battery. Moreover, the charger cannot exchange information with the protection board whe...
