Power supply device and power supply system

Abstract

The embodiment of the invention provides a power supply device and a power supply system, and relates to the technical field of battery thermal management. The power supply device comprises a liquid-cooling plate, heat dissipation plates and a battery module, wherein the liquid-cooling plate comprises a passage, the passage is used for a liquid to pass through and penetrates through a first side surface and a second side surface, which are opposite to each other, of the liquid-cooling plate, the heat dissipation plates are arranged on a third side surface of the liquid-cooling plate at equal intervals, the battery module comprises a plurality of single batteries, each single battery is arranged among the heat dissipation plates arranged at equal intervals, and heat of the single batteries is dissipated by the heat dissipation plates and the liquid-cooling plate. The power supply device and the power supply system can be used for rapidly dissipating heat of the battery module, so that the battery module works in a relatively excellent charge-discharge state, the service lifetime of the battery is further prolonged, the performance of the battery is further improved, and electric energy output stability, safety and reliability of the battery are ensured.

Description

technical field [0001] The present invention relates to the technical field of battery thermal management, in particular to a power supply device and a power supply system. Background technique [0002] With the rapid development of electronic technology, the application fields of batteries are becoming wider and wider. However, as far as the battery itself is concerned, there are still many technical problems to be solved, among which the service life and capacity fading of the battery are an important problem. [0003] The service life and capacity fading of the battery are closely related to the temperature difference and temperature rise of the battery. Generally, a battery generates a large amount of heat during charging and discharging. If the heat cannot be discharged in time, the temperature inside the battery will continue to rise, causing the temperature difference inside the battery to gradually increase. The battery is often very sensitive to temperature change...
