Embodiment
Below against accompanying drawing, by the description to optimum embodiment, specific embodiment of the present utility model is made into one
Step detailed description.
The liquid cooling system of Battery case is used to cool to the battery bag in Battery case, and it includes water cooling tube, water cooling
Plate, the cryogenic liquid or high-temp liquid that water inlet enters, is sent in cooled plate by water cooling tube, and heat exchange is carried out with battery bag
After take away heat or provide heat；Water cooled pipe connects delivery port, and the fluid removal after heat exchange is realized to battery work
The control of temperature, so as to realize battery liquid cooling system.Technical scheme is aiming at this battery with water-cooling system
Pack protection system.As shown in figure 1, a kind of cold cell p ack leakages protection system of liquid, the cold cell p ack of liquid pass through the cold system of liquid
System is cooled or heated to battery, and liquid cooling system is taken away heat that battery sends by water cooling tube, cooled plate or carried for battery
Heating load.Leakage protection system includes multiple leakage detections for being used to detect the liquid cooling system leakage state in Battery case and passed
Sensor 1, the diverse location being separately positioned in Battery case, for detecting the leak leakage signal of liquid cooling system；Leakage detects
The link control module 5 of sensor 1 be used for the leakage signal of detection is sent in control module 5, control module 5 be single-chip microcomputer,
The control chips such as PLC are used to be digitized after processing the data transmitted is transferred to cell tube by leakage information
Reason system 6, battery management system 6 perform corresponding operation according to default control strategy.Battery management system 6 is by gathered data
Information is transferred to entire car controller by CAN, shows leakage data by vehicle control unit controls automobile instrument and sends report
Alert signal.Leakage detection sensor 1 can be arranged on the junction of water cooling tube, and the place of connecting is included in water cooling tube and pair of cooled plate
The place that interface, the delivery port of water cooling tube, the water inlet etc. of water cooling tube are easily revealed, lets out due to being easiest to generation in interface
Dew, so can be with significantly more efficient detection, and multiple sensors can be detected at docking port while other positions are also set in battery
Put for detecting, can accomplish that Multiple detection ensures.Leakage detection sensor 1 is resistance-type leakage detection sensor, according to leakage
Liquid causes resistance change and then realizes the detection of leakage information.
Battery management system 6 connects the relay for being arranged on total just, the total negative leading-out terminal of battery bag, for protecting battery, prevents
Only endangered caused by short circuit.Control relay disconnects after the leakage information that control module sends is received, and is arranged on battery bag
Always just, after the relay of total negative leading-out terminal disconnects, battery bag can not outside output voltage, so as to ensure that safety, prevent leakage
Caused short circuit phenomenon burns out automobile circuit.
Control module 5 is connected with photoelectric liquid level sensor, and it is used to after detecting leakage liquid level information liquid level information being sent into
Into control module 5.Control module 5 connects the magnetic valve for being arranged on Battery case bottom leakage fluid dram, and magnetic valve is used for the row of control
The either on or off of liquid mouth.On the one hand the liquid level information detected can be transferred in automobile instrument by photoelectric liquid level sensor shows
Show, on the other hand, when the leakage liquid level that photoelectric liquid level sensor is detected in Battery case, which reaches, sets threshold values, illustrate now
Leakage is serious, need to exclude the liquid in Battery case in time, and otherwise battery short circuit is burnt out or equivalent risk on fire, passes through Battery case
The leakage fluid dram that bottom is set discharges related liquid, liquid electromagnetic valve 3 is set at leakage fluid dram, magnetic valve 3 is controlled by control module 5
Open and close, quickly can open leakage fluid dram when leakage situation is serious.
Control module 5 is connected with gas generating unit 4, the control signal of the receive and control module 5 of gas generating unit 4 and produce
Angry body.Gas generating unit 4 is used to produce protective gas, and gas uses carbon dioxide here, and gas can coordinate electricity
Magnet valve 3 is the liquid of remaining leakage by squeezing out Battery case, and carbon dioxide can also play starvation, resistance
The effect only burnt, occur so as to reduce the accidents such as fire when revealing.
A kind of automobile, its Battery case include water cooling tube, cooled plate using liquid cooling system cooling battery bag, liquid cooling system,
Automobile batteries casing sets the cold cell p ack leakages protection for example above-mentioned technical scheme of system of liquid consistent.
After electrokinetic cell pack systems use the cold scheme of liquid, can there are leakage risk, particularly water pipe docking port position, wind
Dangerous high, the leakage multiple-protection system can be detected in each water pipe docking port location arrangements resistance-type leakage and passed first
Sensor, when large change or leakages occur for certain water pipe docking port position humidity, control module 5 can in real time monitor and leakage position
Put and report battery management system 6 with failure, battery management system 6 makes the place for reporting complete vehicle fault and disconnecting all relays
Reason.
If leakage rate is larger, coolant can flow into Battery case lowest position, now photoelectric level detection sensor 2
