Description
【Technical field】
The utility model is related to automobile batteries bag, more particularly to a kind of system for detecting temperature of battery bag.
【Background technology】
At present, the research and development of new-energy automobile are like a raging fire, and battery is the core component of new-energy automobile, so the safety requirements of automobile batteries will pull into the rank of industry.In the unsafe numerous reasons of battery, temperature rise is almost the necessary process of all failure modes caused by overheat, therefore it is particularly important for the monitoring temperature of automobile batteries, it is big for the lithium ion battery energy of automobile power power supply, joint number is more, the features such as security performance requires high, the monitoring temperature of lithium battery is had to accurately reflect the actual temperature of lithium battery in itself, and can quickly reflect the state of temperature of every batteries, and the automobile batteries used at present mainly passes through temperature sensor（PTC,NTC）Gather the temperature of each battery.Its specific way is：Temperature sensor is first made into temperature acquisition line, temperature acquisition line is pasted onto detection temperature on the battery to be gathered again, this kind of mode, though energy collecting temperature, but because the way of contact between temperature acquisition line and battery is less firm, in process of production because of artificial origin, temperature acquisition line and battery loose contact can be caused, either battery bag in follow-up operation, because vibrations and caused by temperature acquisition line and battery disengaging, cause the error detection of battery temperature, simultaneously, this kind of mode, also not convenient in battery bag production process, low production efficiency.
In view of above drawback, is necessary to provide a kind of system for detecting temperature of battery bag in fact to overcome drawbacks described above.
【Utility model content】
The utility model is simple in construction, cheap for manufacturing cost there is provided one kind, and can increase the system for detecting temperature of the battery bag of automotive safety stability.
To achieve these goals, the utility model is adopted the following technical scheme that:A kind of system for detecting temperature of battery bag, circuit board including being connected to tested battery two poles end, it is arranged at the temperature sensing device on circuit board, signal wire in embedded circuit plate and the connector being installed on circuit board, the two ends of the signal wire are respectively connecting to temperature sensing device and connector, foregoing temperature sensing device, signal wire and connector does not have electric connection with being connected the circuit board of battery, and described connector is external to the security system of vehicle.
Improved as a kind of the of system for detecting temperature of the utility model battery bag, the temperature sensing device is unclosed frame structure, and it is installed in the surrounding them of tested battery.
Improved as a kind of the of system for detecting temperature of the utility model battery bag, the temperature sensing device is PTC or NTC thermistor.
The utility model has advantages below compared with prior art：1）Wiring is simple, is easy to batch production, reduces production cost；2）Good stability, is not susceptible to because the detection that connection is insecure and occurs is inaccurate, the phenomenon such as no detection signal.3）Signal detection is sensitive.
【Brief description of the drawings】
Fig. 1 is the structural representation of the system for detecting temperature of the utility model battery bag.
【Embodiment】
It refer to shown in Fig. 1, a kind of system for detecting temperature of battery bag, it includes having some for the electrode through hole 11 being electrically connected with of cell in battery pack and the air vent 12 being distributed near through hole according to certain rule setting on the circuit board 10 of generally rectangular shaped shape, the circuit board 10.Some temperature sensing devices 20 are provided with circuit board 10, the temperature sensing device 20 is preferably PTC or NTC thermistor.Along temperature sensing device 20 signal wire 30 being connected with turn in embedded circuit plate and the plug connector 40 for being installed in circuit board surface, the connector 40 is external to the security system of whole electric motor car, and foregoing temperature sensing device 20, signal wire 30 and connector 40 does not have electric connection with being connected the circuit board of battery.
The system for detecting temperature of the utility model battery bag so works：First, the two poles of the earth of battery pack are separately fixed on two independent circuit boards, then the plug connector of circuit board surface is external to the security system of electric motor car.After the cell in battery pack produces heat in the course of the work, it will be transferred to the aggregation of heat by way of heat transfer on circuit board, PTC or NTC thermistor are transferred to again, PTC or NTC thermistor can work according to battery pack to be produced the change of heat and causes its resistance to change, the signal of change in resistance is sent to the security system of electric motor car by signal wire and plug connector, so as to realize the monitoring and alarm to temperature.
The system for detecting temperature of the utility model battery bag, it is not restricted to described in specification and embodiment, therefore additional advantage and modification are easily achieved for the personnel of familiar field, therefore in the case of the spirit and scope of the universal limited without departing substantially from claim and equivalency range, the present invention is not limited to specific details, representational equipment and shown here as the examples shown with description.
