Description
Technical field
The utility model belongs to the battery management system field of electric vehicle, and in particular to BMS thermal management device of batteries.
Background technology
Electric automobile and hybrid power vapour have become the important vehicles at present, and electrokinetic cell is pure electric automobile
The energy carrier driven with hybrid vehicle, in order to meet quick charge and continue the requirement of mileage, and climbing, acceleration etc.
Vehicle energy under operating mode, electrokinetic cell must possess high-power output and Large Copacity.In order to ensure the high power capacity of electrokinetic cell,
It is high-power, a large amount of single power batteries are generally formed into battery modules by way of series, parallel and used.
Electrokinetic cell operating current is big, and quantity of heat production is big, while battery pack is in the environment of a relative closure, is easily led
The temperature for sending a telegraph pond rises, because the electrolyte in lithium battery, electrolyte plays electric charge conduction in lithium battery interior.Mesh
Preceding lithium battery is largely inflammable, volatile non-aqueous solution composition, and this compositional system is compared to aqueous electrolyte composition
Battery has higher ratio energy and voltage output, meets user Geng Gao energy requirement.Because non-aqueous electrolyte is easy in itself
Fire, be volatile, infiltrating in inside battery, also form the burning root of battery.Therefore the operating temperature of lithium battery material must not
Higher than 60 DEG C, but for summer outdoor temperature often close to 40 DEG C, while battery quantity of heat production itself is big, this will cause the work of battery now
Make environment temperature rising, and will be extremely dangerous if there is thermal runaway, situation.In order to avoid becoming " to roast ", radiated to battery
With regard to particularly important.
Battery pack radiating has actively and passively two kinds, there is very big difference in efficiency between the two.Passive system is wanted
For the cost asked than relatively low, the measure taken is also simpler.Active system structure is more relative complex, and needs bigger additional work(
Rate, but its heat management is more efficient.
In addition, being exactly the effect of battery diaphragm, the positive and negative step of battery is separated mainly in small space, prevented
The two poles of the earth contact causes short circuit, but can guarantee that the ion in electrolyte passes freely through between both positive and negative polarity.Therefore barrier film is just into guarantor
Demonstrate,prove the core material of lithium ion battery safe and stable operation.
Electrolyte is to completely cut off burning source, and barrier film is to improve heat resisting temperature, and it is fully then to reduce electricity to radiate
Pond temperature, accumulated heat is avoided excessively to trigger battery thermal runaway.If battery temperature is drastically increased to 300 DEG C, even if barrier film does not melt
Change shrink, electrolyte itself, electrolyte and both positive and negative polarity can also occur harsh chemical reaction, discharge gas, formed internal high pressure and
Blast, so most important using suitable radiating mode.
In the prior art, the conventional type of cooling of battery pack is mainly water cooling or air cooling, such as during air cooling, if fruit is changed
Hot-air fan is continued for work, then hot-swappable fans in itself also due to acting distribute heat, cause the working environment temperature of battery pack
Degree rises.And if simply cooled again after battery pack is warming up to certain temperature, due to changing for air and battery surface
Hot coefficient is relatively low, can not carry out effective temperature-reducing control to battery pack in a short time.And the heat exchanger of water-cooled cooling is at one section
Interior cooling-down effect is notable, but sealing requirements are high, and quality is relatively large, and maintenance and maintenance are complicated, and structure is relative complex.And
And after working long hours, because the operating ambient temperature rise of the whole dynamical system of vehicle causes water-cooled effect to decline, or
Need in use for some time, it is necessary to which the water in water jacket is replaced.
