Title:
POWER BATTERY VOLTAGE REGULATION CIRCUIT AND SYSTEM, AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/216488
Kind Code:
A1
Abstract:
The present application provides a power battery voltage regulation circuit and system and a control method thereof. The power battery voltage regulation circuit comprises a power battery, a heating module, a charging and discharging interface and a voltage regulation module. The heating module comprises a power energy storage element and a switch module. The power battery is in parallel connection with the switch module. The external charging and discharging device is in connection with the power battery through a charging and discharging interface. The voltage regulation module comprises multiple switches and an energy storage regulation element, and the multiple switches and the energy storage regulation element being arranged between the charging and discharging interface and the power battery. The voltage regulation module and the switch module are used for adjusting the charging and discharging voltage between the power battery and the power energy storage element and regulating the charging voltage of the external charging and discharging device to the power battery in response to the voltage regulation control signal. The charging and discharging voltage between the power battery and the power energy storage element can be flexibly and efficiently regulated, and the charging voltage of the external charging and discharging device to the power battery is can be regulated.
