Abstract

The invention discloses an all-environment operational intelligent lithium battery compartment, comprising a sealed shell; a battery pack soaked in a heat transfer substance, a battery management system and a heating semiconductor are arranged in the shell; the battery management system comprises a sampling circuit, a master controller, a power circuit, a temperature detection control circuit and a wireless data transmission module; the sampling circuit acquire remaining capacity and life of the battery pack and transmit them to the master controller; the temperature detection control circuit acquires inner temperature data of the battery pack and transmit it to the master controller; when the inner temperature data of the battery pack is lower than a set temperature, the master controller issues a heating command to the temperature detection control circuit, the temperature detection control circuit controls the heating semiconductor to start heating, the master controller transmits the acquired remaining capacity and life of the battery pack to a cloud platform or a mobile terminal through the wireless data transmission module. The all-environment operational intelligent lithium battery compartment allows a lithium battery to operate normally at high temperature or low temperature and can provide extended cycle life for the lithium battery.

Description

technical field [0001] The invention relates to the battery field, in particular to an all-environment working intelligent lithium battery compartment. Background technique [0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from a rechargeable lithium-ion battery or lithium-ion polymer battery. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements for power supply. Lithium batteries have entered a large-scale practical stage. With the application of lithium batteries more and more widely, such as: used in two-wheel electric vehicles, four-wheel electric vehicles, electric vehic...
