Parallel battery pack and control method

The invention discloses a parallel battery pack and a control method in the field of battery management. The parallel battery pack comprises a battery pack shell; the battery pack shell is provided with a connecting socket and a battery management circuit board, and the battery packs are connected in parallel through the connecting socket; the battery management circuit board comprises a micro control unit (MCU); the charging and discharging enabling positive electrode interface K+ and the charging and discharging enabling negative electrode interface K- are electrically connected to the micro control unit MCU; the charging and discharging positive electrode interface PACK+ is electrically connected with the battery through the charging and discharging field effect transistor circuit; when the charging and discharging enabling positive electrode interface K+ and the charging and discharging enabling negative electrode interface K- are in a disconnected state, the MCU disconnects the charging and discharging p
