The invention discloses a battery charging protection method and device, and relates to the technical field of battery pack charging or control, and the method comprises the following steps: after a battery is connected with an external charger, a plurality of working condition group parameters of the battery are collected in real time, and the working condition group parameters comprise one or more different working condition parameters; determining each different protection mode triggered by each collected working condition group parameter, wherein the plurality of protection modes have different priorities; if only one protection mode is triggered, executing the protection mode; and if the plurality of protection modes are triggered at the same time, only executing the protection mode with the highest priority. According to the invention, each working condition parameter of the battery is comprehensively monitored when the battery is charged, working condition group division is carried out according to the working condition parameters to determine a relatively suitable protection mode, and priority selection is carried out when a plurality of protection modes conflict to determine the most suitable protection mode so as to ensure the reliability and safety of the battery during charging.
Description
technical field [0001] The present application relates to the technical field of battery charging or control, and in particular to a battery charging protection method and device. Background technique [0002] With the rapid development of the economy, electric vehicles or battery vehicles or other electrical equipment have penetrated into people's lives. However, incidents of spontaneous combustion / explosion of electric vehicles still occur from time to time. [0003] Most of the related technologies simply limit the load overcurrent or overvoltage to prevent the battery from spontaneous combustion / explosion, and cannot adjust the current or voltage. It is easy to cause insufficient safety protection due to the fixed setting of the protection threshold, and also cause damage to the battery. The probability increases. [0004] However, the reasons for battery spontaneous combustion / explosion are complex, and how to improve the safety and reliability of batteries during char...
