Problems solved by technology
[0005] The present invention provides a lithium-ion battery pack to overcome the shortcoming of tight space in the horizontal direction and surplus space in the height direction in the prior art. Due to the placement of the battery module, the energy density of the battery pack is relatively small, so as to realize the placement of more battery packs in the same space. More battery modules can effectively improve the utilization rate of lithium battery packs in the height space direction, thereby increasing the energy density of lithium electronic battery packs

The invention provides a lithium ion battery pack. The device of the present invention comprises: a battery pack lower box, at least two battery modules, a switch box and a battery pack upper cover, and at least two battery modules adjacent to each other are placed sideways in a back-to-back manner At the bottom of the lower box of the battery pack, so that the length direction of the battery module is consistent with the width direction of the lower box of the battery pack, and the height direction of the battery module is consistent with the length direction of the lower box of the battery pack; and at least two batteries A water cooling plate is arranged between two adjacent battery modules in the module. In the lithium-ion battery pack of the present invention, by placing the battery modules on the side and assembling them back-to-back, the width direction of the battery module is matched with the length direction of the lithium-ion battery pack, which can improve the battery pack with a surplus of height space. Space utilization in the height direction, thereby achieving an increase in the energy density of the lithium-ion battery pack. And the structure is compact, the assembly is simple, and it is easy to achieve mass production.
Description
【Technical field】 [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a lithium-ion battery pack. 【Background technique】 [0002] At present, with the rapid development of the new energy vehicle industry, how to improve the stable and safe battery life of new energy vehicles has attracted more and more attention. Among the existing power batteries for new energy vehicles, lithium-ion batteries have relatively low production costs, can be recharged repeatedly, and are very convenient to use. Compared with other portable energy sources, lithium-ion batteries have a higher cost advantage. [0003] In the prior art, to improve the battery life of the entire lithium-ion battery pack, in addition to placing as many batteries as possible in the limited vehicle space, increasing the energy density can also effectively improve the battery life of the lithium-ion battery. Improvement, that is, placing as many battery modules as possible in a...
