The present invention relates to air guide in a kind of battery case, the manufacture technology field of heat-transfer device, it is especially a kind of can heat conduction, row
The battery PACK box structures of gas and waterproof.
Background technology
The topmost core of electric automobile is exactly battery, and the lithium battery that present electric automobile is all, battery is by electricity
Pond case series connection, each battery case is made up of battery core connection in series-parallel.BMS is battery management system, to each battery core and whole
Car voltage is monitored, and temperature, voltage of battery core etc. are detected, can be alarmed when the core voltage that often economizes on electricity is more than 4.2V, BMS can be certainly
Dynamic to cut off the electricity supply, electric control can be stopped.PACK is exactly battery case, and BMS+PACK is exactly a combination, in order to more effective
The safer combination that power is provided to automobile.It is indispensable just as motor and automatically controlled.In order to ensure the normal work of battery
Make, heat conduction, gas extraction system must also be provided with PACK battery cases, the gas and heat that will can be produced in PACK battery cases
Discharge, so can guarantee that the normal work of battery in time.But the casing of existing PACK battery cases is made up of metal material, not only
Cost is high, and heavy, so that the weight of electric automobile accordingly increases, i.e., consumption rate is also big；Also bigger shortcoming is,
Exhaust in existing PACK battery cases is realized by air bleeding valve, but installation air bleeding valve will take the space in battery case, no
The packing fixed space of battery in battery case is only occupied, makes battery pack be difficult to install, same battery pack to be such as installed, then battery
The volume of case will increase, and volume can also increase so for electric automobile, i.e. energy density ratio is substantially reduced, and practicality is inadequate
It is good, so its structure needs to improve.
The content of the invention
The technical problems to be solved by the invention are that to provide a kind of design structure for above-mentioned state of the art ingenious,
