Background technology
Along with the continuous attention to problems such as global environment deterioration and resource minimizings, sight line is transferred on new-energy automobile by Ge great automobile factory.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 accurate acquisition, control in time, battery will be had influence on, cause fault, jeopardize safety.Usual employing temperature sensor carries out temperature acquisition to electrokinetic cell, and temperature sensor is arranged in position on electrokinetic cell, the reliability of laminating and thermal environment, larger to temperature acquisition Influence on test result.
At present, otherwise adopt the method for binding, be fixed on battery plus-negative plate ear, or be fixed on battery case.Otherwise adopting is fixed on lug plate by temperature sensor, and lug plate is fixed on battery plus-negative plate ear.The shortcoming of said method is the diverse location that the data of battery temperature sensor collection come from relative to battery cell, and its data can not embody the temperature consistency between battery;
The temperature that temperature sensor gathers, not only from battery, some is by the impact of clearance air between temperature sensor and battery, and heat transfer area is little, is even point cantact.These factors have the risk 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 the security performance of battery and life-span are the problems that prior art needs to solve.
