Problems solved by technology

However, in the prior art, this kind of battery has the risk of thermal runaway due to switch failure.
The cooling of the battery mainly uses external water-cooled plates or air-cooled methods, but these methods have poor cooling effects and slow speeds
The development of stable, efficient, and high-rate battery temperature regulation technology still faces great challenges

Embodiment Construction

[0032] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] A specific embodiment 1 of a hard shell battery of the present invention, such as figure 1 As shown, the hard-shell battery is square and consists of a battery case 5 and a battery cell 6. The battery case 5 is composed of an outer wall 1 and an inner wall 2, and a channel is formed between the outer wall 1 and the inner wall 2 for the passage of the heat exchange medium. The heat exchange medium passage 4, the battery case 5 has an inlet 3 for the heat exchange medium to flow into the heat exchange medium passage 4 of the battery case 5 and a heat exchange medium passage for the heat exchange medium to flow out of the battery case 5 Exit 9 of 4. The inlet 3 and outlet 9 of the hard case battery are on opposite sides of the battery housing 5 . The cell 6 of the hard case battery has a positive terminal 7 and a negative terminal 8 which are arran...

Abstract

The present invention relates to a hard-shell battery and a battery housing thereof. The hard-shell battery comprises a cell and a battery housing coating the cell, the battery housing is internally provided with a medium channel used for circulation of a heat transferring medium, the battery housing is provided with an inlet used for flow-in of the heat transferring medium and an outlet used forflow-out of the heat transferring medium, the battery housing is provided with the inlet and the outlet, and the battery housing is internally provided with a medium channel. The heat transferring medium flows in the medium channel of the battery housing and flows out through the outlet, the heat transferring medium is subjected to heat exchange with the cell coated with the battery housing to achieve the purpose of temperature regulation of the hard-shell battery. The hard-shell battery and the battery housing thereof with stable temperature regulation and high regulation rate are provided.

Description

technical field [0001] The invention relates to a hard case battery and the battery casing thereof. Background technique [0002] The development of new energy vehicles is of great significance to saving resources and improving the environment. At the same time, the development of batteries, the energy source of new energy vehicles, is crucial to the promotion of new energy vehicles. A conventional battery includes a positive electrode, a negative electrode, a separator, a positive electrode current collector, a negative electrode current collector, an electrolyte and a battery cover, and the cell part also includes a battery case part. Lithium-ion batteries have become the first choice for new energy vehicle batteries due to their advantages such as high energy density, high power density, long life, and no memory effect. [0003] However, the performance of lithium-ion batteries is limited by the ambient temperature. In a low-temperature environment, due to the rapid dec...
