The invention discloses a constant-temperature battery pack. The battery pack comprises a plurality of batteries, other components, a split type sealed shell for encircling the batteries and other components, and insulation cooling liquid which is injected into the sealed shell. Therefore, the insulation cooling liquid can flow to the any position in the sealed shell, and is in sufficient contact with heating components such as the batteries and relays, so that heat transfer is implemented at various positions. Compared with the prior art, the constant-temperature battery pack has the advantages that the heat exchange area is increased, and the cooling effect on the heating components such as the batteries and the relays can be greatly improved, so that the temperatures of the various components in the battery pack are constant within the target temperature zone, and the electrical performance of the battery pack can be sufficiently developed. As all the components are immersed into the insulation cooling liquid, the temperature inside the battery pack is uniform, and the charging and discharging performance of the battery pack can be improved. In addition, as the insulation cooling liquid cannot react with the batteries, compared with the prior art, the battery pack has the advantages that the phenomenon that the batteries are damaged due to soaking of the batteries can be avoided simultaneously while the cooling effect is improved.
