Description
Technical field
The present invention relates to batteries of electric automobile field, be specifically related to a kind of battery bag liquid cooling/heating systems assay device.
Background technology
Along with the deterioration increasingly of the problems such as energy crisis, global warming, environmental pollution, new-energy automobile is the developing direction of future automobile.At present, the developing direction of new-energy automobile is concentrated mainly on hybrid vehicle and pure electric automobile.And battery and battery Bao Ze are the critical components of hybrid vehicle and pure electric automobile.
At present, electric automobile mainly uses dynamic lithium battery, and the principal element affecting the electrokinetic cell life-span has the charge-discharge magnification of battery, discharge and recharge blanking voltage, shelves condition, uses temperature etc., and these factors influence each other, and mutually restrict.But for using temperature, current electrokinetic cell monomer all cannot normal operation under the environment of extreme low temperature (less than-30 DEG C) and thermal extremes (more than 50 DEG C).For dynamic lithium battery heat dissipation problem, industry has invented different chillers, mainly has gas cooling, liquid cooling and phase-change material cooling.At present, commonly used the simplest air cooling on market, but, if batteries of electric automobile works under severe thermal environment, rely solely on air cooling and be difficult to make the battery operated temperature range in the best.Owing to liquid cold but system heat transfer efficiency is high, it is little to take volume, but relatively costly, it is particularly important so developing a kind of electrokinetic cell liquid-cooling system efficient, compact, low cost.
Summary of the invention
Various aspects of the invention are devoted to provide a kind of battery bag liquid cooling/heating systems assay device.The present invention adopts the following technical scheme that
A kind of battery bag liquid cooling/heating systems assay device, it is characterised in that include compressor, condenser capillary tube, vaporizer, circulating pump, reserving liquid tank, effusion meter, electromagnetic valve, pressure transducer, temperature sensor and battery bag；Reserving liquid tank is provided with electrically heated rod, and condenser is with condenser fan；
Compressor, condenser, capillary tube, vaporizer constitute a loop, and vaporizer, circulating pump, reserving liquid tank and battery bag constitute another loop, are provided with effusion meter, electromagnetic valve, pressure transducer and temperature sensor on this loop；Effusion meter, electromagnetic valve, pressure transducer, temperature sensor；Battery bag liquid cooling/heating systems assay device according to claim 1, it is characterised in that the number of described battery bag is not limit.
The number of described battery bag is not limit.
Can be electrokinetic cell in described battery bag, it is also possible to be used to the electrically heated rod of simulated battery work.
Described battery bag is provided with the inlet and outlet of liquid, and the position of import and export is unrestricted.
Described battery bag external application heat-insulation layer.
When battery bag temperature is higher than 60 DEG C of needs coolings, compressor and circulating pump start, and battery pouring-basket cooling system works, and makes battery bag temperature maintain 25 DEG C～40 DEG C；When battery bag is operated under the low temperature condition lower than 0 DEG C, electrically heated rod and circulating pump work, by adding hot liquid and then battery bag being heated；When coolant is heated to uniform temperature, electrically heated rod and circulating pump quit work, and close the electromagnetic valve of import/export, and now battery bag is in holding stage, makes battery bag temperature maintain 25 DEG C～40 DEG C.
