Abstract

The invention relates to a 48V start-stop power supply and an electric vehicle, and the 48V start-stop power supply comprises a power supply enclosure frame (1) which is provided with a liquid cooling inlet (11) and a liquid cooling outlet (12); a battery core assembly (2) arranged in the power supply enclosure frame (1); a liquid cooling assembly (3) arranged on at least one side of the battery cell assembly (2), wherein a liquid cooling flow channel is formed in the liquid cooling assembly (3), and the two ends of the liquid cooling flow channel are connected with the liquid cooling inlet (11) and the liquid cooling outlet (12) respectively. According to the 48V start-stop power supply, the liquid cooling assembly is additionally arranged, and the liquid cooling inlet and the liquid cooling outlet are formed in the power supply enclosure frame, so that the 48V start-stop power supply forms a battery pack structure with a liquid cooling function, and the 48V start-stop power supply is safer and longer in service life.

Description

technical field [0001] The present disclosure relates to the field of new energy vehicles, in particular, to a 48V start-stop power supply and an electric vehicle. Background technique [0002] In new energy vehicles, it is usually necessary to reduce the volume of the power battery as much as possible to achieve the goal of minimizing space occupation and cost. For this reason, the 48V start-stop power supply currently on the market usually does not design a cooling system, and the battery will reduce its service life if it is overheated for a long time, and severe overheating may even cause thermal runaway. Contents of the invention [0003] The purpose of the present disclosure is to provide a 48V start-stop power supply and an electric vehicle. The 48V start-stop power supply has good safety and long service life. [0004] In order to achieve the above purpose, the first aspect of the present disclosure provides a 48V start-stop power supply, including: [0005] The ...
