Abstract
The invention discloses a high-capacity battery pack with a temperature control protection function. The high-capacity battery pack comprises a battery fixture, battery mounting holes, metal elastic sheets, upper layer single batteries and lower layer single batteries, wherein the battery mounting holes are formed on the battery fixture; the metal elastic sheets are arranged in the battery mounting holes; the upper layer single batteries and the lower layer single batteries are inserted in the battery mounting holes; both the upper layer single batteries and the lower layer single batteries are connected with the metal elastic sheets so as to achieve series connection of the upper layer single batteries and the lower layer single batteries; and thermally conductive and insulating spacers are arranged in the battery mounting holes and at the bottoms of the metal elastic sheets. According to the invention, the thermal runaway phenomenon of the battery pack can be prevented; the high-capacity battery pack takes an effect of a fuse when thermal runaway occurs; and safety of the battery pack is enhanced.
Description
technical field [0001] The invention relates to a large-capacity battery pack with temperature control and protection functions, and belongs to the technical field of battery pack temperature control. Background technique [0002] With the rapid development of electronic technology, cylindrical lithium-ion batteries with high specific energy and high performance have been widely used. This type of battery has high working voltage, long cycle life, and does not contain harmful substances. It is the most ideal independent power supply product today. However, it has a high storage energy and uses organic matter as the electrolyte, which is inherently in danger of fire and explosion. In fact, there have been some fire and explosion accidents. Therefore, the safety issue is the main short board of this type of battery. [0003] The main hidden danger of battery safety mainly comes from the thermal runaway of the battery. The thermal reaction of the battery is mainly divided in...
