Beschreibung
Zusammenfassung:	The invention belongs to the technical field of charging and discharging of medical batteries, and particularly relates to a double-battery switching circuit, which multiplexes PMOS tubes for charging and discharging batteries, and only needs to control the states of four PMOS tubes, and switches of double batteries are formed by a pair of mirror image PMOS tubes. The circuit can reduce the number of electronic components, reduce the occupied area of the circuit, and reduce the cost. 本发明属于医用电池充放电技术领域，具体是一种双电池切换电路，该电路将电池充电与放电的PMOS管的复用，只需控制4个PMOS管状态，双电池的开关均由一对镜像PMOS管构成。该电路可减少电子元器件数量、减小电路占用面积，降低成本。
