The target module also includes the real-time clock module. The real-time clock module is used to generate clock information, send the clock information to the control module, and receive the power supply signal. The clock information is used to instruct the control module to go into sleep or wake up.

10. The integrated battery management system of claim 9, wherein, The real-time clock module includes a crystal oscillator unit, a frequency divider, a clock and calendar unit, an alarm register, a timing register, and an interrupt control unit, wherein: The first terminal of the crystal oscillator is electrically connected to the fourth terminal of the power management module. The second terminal of the crystal oscillator is electrically connected to the first terminal of the frequency divider. The second terminal of the frequency divider is electrically connected to the first terminal of the clock and calendar unit and the first terminal of the timing register. The second terminal of the clock and calendar unit is used to electrically connect to the control module. The third terminal of the clock and calendar unit is electrically connected to the first terminal of the alarm register. The first terminal of the interrupt control unit is electrically connected to the second terminal of the alarm register and the second terminal of the timing register. The second terminal of the interrupt control unit is used to electrically connect to the control module.

11. An integrated battery management device, the device comprising a device body, the device further comprising an integrated battery management system as described in any one of claims 1-10.
