VEHICLE-MOUNTED POWER BATTERY, RECHARGEABLE ENERGY STORAGE SYSTEM, AND ELECTRIC CAR

A vehicle-mounted power battery (20) is provided, including a housing (1), a charging reception coil (2), and a battery core module (3). The housing (1) includes a groove (101) disposed on an outer surface of the housing (1) and an accommodation cavity (102) disposed in the housing (1). The charging reception coil (2) is accommodated in the groove (101), and is configured to receive energy from a power supply apparatus (10) and output the energy. The battery core module (3) is accommodated in the accommodation cavity (102) and electrically connected to the charging reception coil (2), and is configured to receive and store the energy output by the charging reception coil (2). The vehicle-mounted power battery (20) has a simple structure, and it is less difficult to assemble a production line. This helps improve production efficiency. In addition, a chargeable/dischargeable energy storage system (100) and an electric vehicle (300) include the vehicle-mounted power battery (20).
