US 2026/0291266 A1 · Control system and control method of battery pack charging/discharging, and garden tool system

Abstract

A control system and a control method of a battery pack charging/discharging, and a garden tool system are provided. The control system of the battery pack charging/discharging includes a battery module, a power board module and a motherboard module. The power board module includes a plurality of connecting terminals, and the plurality of the connecting terminals is connected with a power tool or a charger. The motherboard module is connected with the battery module and is used to collect parameter information of the battery module. The motherboard module is further connected with the power board module, the motherboard module controls a charging/discharging of the battery module based on the power board module, and the motherboard module and the power board module are formed on different circuit boards.
