The invention relates to a power-on and power-off management system and method for a battery, and the system comprises a power supply unit which comprises at least one battery; the control unit comprises an MCU (Microprogrammed Control Unit) chip; the sampling unit comprises an analog sampling chip AFE, and the sampling unit is connected with the power supply unit and the MCU chip; the switch unit is arranged at the positive electrode output end or the negative electrode output end of the power supply unit, the switch unit comprises at least one MOS tube, and a grid electrode of the MOS tube is connected with an analog sampling chip AFE; the signal input unit is connected with the I/O port of the MCU chip, the signal input unit comprises a signal input end DETD and a signal output end, the signal input end DETD obtains an activation signal, and the activation signal comprises a high-level signal or a low-level signal. According to the invention, the MCU can be triggered through one I/O port to carry out on-off control, that is, input and output of the same circuit can be realized through one I/O port, so that a scheme of controlling a positive electrode or a negative electrode is realized only through one I/O port.
