The invention relates to the technical field of batteries, and discloses a multi-pack parallel charging and discharging control method and device for battery packs, and the method comprises the steps: obtaining the current state information of each battery pack in a parallel total pack which is formed by connecting a target battery pack with at least one other battery pack in parallel; in response to a preset starting signal of the target battery pack, determining a charging and discharging mode of the target battery pack according to the preset starting signal; performing charge-discharge sorting on the target battery pack based on the charge-discharge mode of the target battery pack and the current state information of all the battery packs, and controlling the target battery pack to enter the charge-discharge mode; and calculating total pack charging and discharging power data of the target battery pack, and performing charging and discharging control on the target battery pack based on the total pack charging and discharging power data. The method can overcome the defects of parallel charging and discharging of a plurality of existing independent battery packs, has the advantages of high control efficiency and low cost, can guarantee safe charging and discharging of the parallel battery packs, and further improves the user experience.
本发明涉及电池技术领域,公开了一种电池包的多包并联充放电控制方法及装置,方法包括:获取并联总包中每一电池包的当前状态信息,其中,并联总包是由目标电池包与至少一个其他电池包并联构成的;响应于目标电池包的预设启动信号,根据预设启动信号确定目标电池包的充放电模式;基于目标电池包的充放电模式和所有电池包的当前状态信息对目标电池包进行充放电排序,控制目标电池包进入充放电模式;计算目标电池包的总包充放电功率数据,并基于总包充放电功率数据对目标电池包进行充放电控制。本发明能够克服现有多个独立电池包并联充放电的缺陷,具有控制效率高、成本低的优势,能够保障并联电池包的安全充放电,进一步提升了用户使用体验。
