Description
Technical field
The present invention relates to the electrokinetic cell of electric automobile, particularly a kind of arrangement of electric automobile power battery temperature sensor.
Background technology
Along with the continuous attention to problems such as global environment deterioration and a resource shrinkages, Ge great automobile factory transfers to sight line on new-energy automobile.The various electric motor cars such as hybrid vehicle, pure electric automobile, extended-range electric vehicle emerge in an endless stream.
In electric motor car, electrokinetic cell is critical piece, if the temperature of battery can not accurately gather, control in time, will have influence on battery, causes fault, jeopardize safety.Conventionally adopt temperature sensor to carry out temperature acquisition to electrokinetic cell, temperature sensor is arranged in reliability and the thermal environment of position on electrokinetic cell, laminating, larger on the impact of temperature acquisition result.
At present, otherwise adopt the method bundling, be fixed on battery plus-negative plate ear, or be fixed on battery case.Otherwise adopt, temperature sensor is fixed on lug plate, lug plate is fixed on battery plus-negative plate ear.The shortcoming of said method is that the data of battery temperature sensor collection come from the diverse location with respect to battery cell, and its data can not embody the temperature consistance between battery;
The temperature that temperature sensor gathers, not only from battery, some is subject to the impact of clearance air between temperature sensor and battery, and heat transfer area is little, is even some contact.These factors have the risk of making the distortion of temperature of powered cell image data.
For the problems referred to above, for temperature of powered cell sensor provides a kind of novel arrangement, for battery thermal management system provides problem data accurately, ensure that security performance and the life-span of battery is the problem that prior art need to solve.
Summary of the invention
Technical matters to be solved by this invention is, a kind of arrangement of electric automobile power battery temperature sensor is provided, and for battery thermal management system provides problem data accurately, reaches and ensures the security performance of battery and the object in life-span.
For achieving the above object, technical scheme of the present invention is that a kind of arrangement of electric automobile power battery temperature sensor, is characterized in that: described arrangement is that temperature sensor is arranged on the collection point directly over each electrokinetic cell; Temperature sensor is provided with heat-conducting glue, the skin parcel adiabatic gum of heat-conducting glue.
Described heat-conducting glue fills up temperature sensor and electrokinetic cell gap.
Described temperature sensor is fixed on electrokinetic cell by the bonding of heat-conducting glue and adiabatic gum.
Described collection point is positioned at the centre of the positive and negative lug of electrokinetic cell, and the relative position on each electrokinetic cell is identical.
An arrangement for electric automobile power battery temperature sensor, owing to adopting above-mentioned structure, the present invention fixes the position of battery temperature sensor; Battery temperature sensor fixed form is fixed; For battery thermal management system provides problem data accurately, ensure safety, performance, the life-span of battery; Simple in structure, cost is lower.
