Description
Technical field
The utility model discloses a kind of power battery temperature barriers, belong to cell safety protection technology field.
Background technique
With the fast development of electric automobile market, power battery is got a lot of applications.Power battery is that tool mentions
For the power supply of power resources, Duo Zhiwei electric car, electric train, electric bicycle, golf cart provide the electric power storage of power
Pond.
The problems such as the course continuation mileage that power battery is shown is short, cycle life is low are always to restrict electric car rapid growth
Principal element, these factors are more sensitive to environment temperature, power battery in hot operation, cycle life shorten, safety
Performance decline；When low-temperature working, charge/discharge capacity decaying is serious, and multiple low-temperature circulation also has certain influence on safety.
Currently, power battery heat protection design mainly improves in terms of System Design, generally more by using thermal stability
High positive and negative pole material, the electrolyte with flame retarding function, high-melting-point diaphragm, ceramic-coated separator, the coating of cathode ceramic surface,
PTC additive etc..
The above measure is again without fundamentally preventing influence of the heat source to power battery.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the purpose of this utility model is to provide a kind of power batteries
Temperature barrier, by taking a variety of safeguard procedures, so that power battery has preferable thermal protection effect, while in power electric
When the accidental explosion of pond, the effect for absorbing explosion wave can be effectively played, prevents battery explosion from causing to injure to people and equipment, had
There is preferable application value.
To achieve the above object, a kind of power battery temperature barrier provided by the utility model, including power battery, glue
Layer, thermal insulation layer, protective shell and cap, it is characterised in that:
The glue-line is J-2090 tough epoxy resin, and encapsulating is in the circumference of power battery, glue-line radial thickness 2mm, institute
It states before glue-line is potted between power battery and thermal insulation layer, a circle thermal shrinkable sleeve is uniformly placed between power battery and thermal insulation layer
Pipe, the specification of heat-shrinkable T bush are any one in diameter 0.8mm, 1mm or 1.5mm specification, insertion and heat in heat-shrinkable T bush
Heat-Shrinkable Tubings internal diameter identical metal bar smears lubricating grease on metal bar, and then encapsulating is heated to the J-2090 toughness ring of liquid again
Oxygen resin, cross-sectional area shared by heat-shrinkable T bush is the 20%~30% of the cross-sectional area of glue-line, to J-2090 tough epoxy tree
After rouge cooling and solidifying, metal bar is extracted from heat-shrinkable T bush.So set, J-2090 tough epoxy resin has preferably
Elastic-plastic deformation can effectively absorb impact energy, J-2090 tough epoxy resin structure when power battery is by foreign impacts
At glue layer there are the through-holes that are made of heat-shrinkable T bush of circle, this is because the Poisson of J-2090 tough epoxy resin compares
Greatly, volume expansion will axially generated when being radially compressed deformation, it is therefore desirable to which there are hold deformation space, and J-2090 toughness
When by high temperature, cured state can soften epoxy resin, can effectively absorb the heat that power battery distributes, and power electric
Explosion time once occurs for pond, is as caused by thermal runaway, J-2090 tough epoxy resin is being impacted after by thermal softening
When, it can effectively absorb shock wave energy.
The heat-insulated periphery for being placed on glue-line and the upper and lower end face of power battery, material is aerogel blanket, with a thickness of
1mm, so set, can effectively completely cut off the heat transmitting between power battery and external environment, what one side power battery generated
Heat will not influence outside manufacture, on the other hand power battery be used under high temperature environment.
The protective shell is formed by connecting by screw thread or by screw and cap, and protective shell is the cylindrical body with cavity,
The bottom of protective shell has threaded hole, and the material of protective shell is the closed-cell aluminum foam of porosity 60%~70%, this is because hole
The closed-cell aluminum foam of gap rate 60%~70% has good impact flexibility and buffering effect, and thermal conductivity is lower, has
Good thermal insulation and fire line are can absorb when 50% deformation occurs for the foamed aluminium that research test shows that porosity is 84%
2.5MJ/cm3Above energy.Thermal spraying ceramic materials inside the protective shell, can effectively completely cut off the hot ring of protective shell inside and outside
Border.
The material of the cap is the closed-cell aluminum foam of porosity 60%~70%, has threaded hole, cap in the middle part of cap
Inside thermal spraying ceramic materials.
Further, also there is wood screw with matching on the threaded hole of the protective shell and cap.So set,
When power battery transports and has enough to meet the need, whole device can be closed with wood screw, improve the storage environment of power battery.
