Lithium battery charging dynamic protection system based on empirical function and wireless data transmission

Abstract

The invention discloses a lithium battery charging dynamic protection system based on an empirical function and wireless data transmission. The system comprises a lithium battery management system, a GPRS data transmission module, a charging voltage monitoring module, a charging current monitoring module, a charging power monitoring module, a temperature detection module, a charging and discharging cycle index monitoring module, a lithium battery capacity monitoring module, a charging time monitoring module, a remote measurement and control terminal and a cloud data platform. By adopting the scheme provided by the invention, the safety level of the battery is determined through the empirical function, the charging voltages and the charging powers of different safety levels are different, and the range of the charging parameters is set according to the safety level, so that the charging condition can be dynamically monitored in real time in a multi-specification, multi-standard and multi-parameter manner, the charging protection of the lithium battery is further realized, and dangers are prevented. In addition, the charging condition can be monitored and recorded in real time through the cloud data platform, and the safety of dynamic charging is further improved.
