Very big (the 300A/h that the current lithium iron phosphate dynamic battery monomer capacity that adopts in electric motor car is done; 400A/h; 600A/h) because internal structure laminates, middle heat loose do not go out that long-time running causes that electrolyte inside is withered, short circuit, expansion be until blast on fire, threatening the safe operation of electric motor car.The problem that grouping is installed is more, and one group of cell is installed in series in vehicle body, uses frame fixation, outside battery and wiring all are exposed to.
At first, the car unavoidable extraneous factor that is in operation makes battery produce the connection electricity, causes accidents such as electric arc, spark, on fire, blast.The serious threat personal safety.The second, together interdependent between battery, the heat of self can not distribute, and forms easily that electrolyte is withered, short circuit, expansion be until blast on fire.Same serious threat personal safety.The 3rd, car is in operation, in case the impact accident takes place, the vehicle body of steel construction if with battery because of accident UNICOM, so, whole vehicle body is exactly the electrified body of 320V voltage, it also is the serious hidden danger of personal safety; And lithium iron phosphate dynamic battery should not be worked being lower than under the low temperature environment above freezing 5 ℃.
The utility model content:
Goal of the invention of the present utility model is to overcome the weak point of above-mentioned background technology and provide a kind of electric motor car when operation battery that can ensure not generate heat, at battery is accidental when being short-circuited arc extinguishing and oil immersion battery case that can adaptive to low-temperature starting automatically.
The following technical scheme of the novel employing of this usefulness:
A kind of oil immersion battery case, comprise housing, place the loam cake on the housing, place the fixed support in the described housing, lithium battery group sheet, battery bracket, place the pole on the housing, described battery bracket places housing bottom, in the space that this battery bracket and housing bottom constitute ceramic electric heater is housed, the battery pack of the lithium battery group sheet formation of described vertical parallel arranged setting is equipped with in the top of this battery bracket, and this its shell of lithium battery group sheet is that soft material is made and with its vacuum seal, described fixed support is equipped with in the top of this battery pack, the upper surface of this fixed support contacts with the lower surface of described loam cake, remaining space in the described housing is full of transformer oil, places an end of the pole in the described housing to immerse transformer oil, and it is stupefied that the outside of this housing is provided with heat radiation.
The utility model that adopts technique scheme compared with prior art, its shell of lithium battery is that soft material is made and with its vacuum seal, places loam cake on the housing to make and constitutes airtight space in the housing; Remaining space in the housing is full of transformer oil, and transformer oil is heated to rise and forms the fluid power circulation, can shed the heat of inside by the stupefied housing of band heat radiation soon, and battery does not generate heat when ensureing the electric motor car operation; Because transformer oil has the arc extinguishing function, accidental battery is short-circuited, and it can knock out electric arc fast, therefore can not produce the blast of catching fire, and has played safety effect; By the preheating of ceramic electric heater, solved the problem of under low temperature environment, using.
As a kind of optimal way of the present utility model, described housing is equipped with the vibroswitch that is connected with its internal wiring outward, and this vibroswitch is connected with D.C. contactor on being serially connected in each lithium battery group sheet by circuit.
When electric motor car in case clash into, vibroswitch disconnects the coil power of contactor immediately, has further guaranteed passenger's safety.
As a kind of optimal way of the present utility model, to be equipped with on the described fixed support and to pass the interface channel that loam cake leads to outside, the top of this interface channel is connected with the respirator that drier is housed.
Transformer oil in the housing is when expanding with heat and contract with cold, and the drier in the respirator can play the protection housing and keep no moisture in the casing.
As a kind of optimal way of the present utility model, described fixed support and battery bracket all are frame-shaped structure.
The fixed support and the battery bracket that are frame shape can guarantee that transformer oil forms good fluid power circulation.
