Detailed description of the invention
Describe specific embodiment of the utility model below in conjunction with the accompanying drawings in detail.
In order to solve above-mentioned technical problem, the open battery temperature control for vehicle of this utility model, it is placed directly on cold heat cycling element by battery component, reduces the space requirement required for temperature control system as much as possible.On the other hand, utilize another road cycling element that conductor temperature regulation unit carries out waste heat and take away/the process of additional heat, and then improve refrigerating/heating efficiency and the response time of conductor temperature regulation unit.In the following description, in order to clearly show that structure of the present utility model and working method, to be described by many Directional words, but should by "front", "rear", "left", "right", " outward ", " interior ", " outwards ", " inwardly ", " on ", the Word Understanding such as D score is for convenience of term, and is not construed as word of limitation.
As in figure 2 it is shown, Fig. 2 is the module diagram of the battery temperature control that this utility model provides.This battery temperature control includes by temperature-control units, i.e. battery component 10.The temperature sensor (not shown) of temperature switch 70 is used for monitoring cell group temperature, and sends unlatching signal or shutdown signal to control unit 60 according to probe value.Control unit 60 controls to be connected with power supply 50, by controlling the closure of power supply 50 and conductor temperature regulation unit 30, as just connect or reversal connection, thus controls the cold and hot surface commutation of conductor temperature regulation unit 30.
Semiconductor refrigerating is also known as electronic cooling, or freezing by thermoelectric action, is the P-N junction utilizing extraordinary semi-conducting material to constitute, forms thermocouple pair, produces Peltier effect, i.e. by the way of unidirectional current freezes.The physical principle of " peltier effect " is: charge carrier moves formation electric current in the conductor, owing to charge carrier is in different energy levels in different materials, when it moves to low-lying level from high level, will discharge unnecessary heat.Otherwise, it is necessary to heat (i.e. showing as refrigeration) is absorbed from the external world.So, when conductor temperature regulation unit 30 just connects power supply 50, first produces heat, and second absorbs heat；When conductor temperature regulation unit 30 reversal connection power supply 50, the first face originally producing heat becomes absorption heat, and the second face originally absorbing heat becomes generation heat.
Temperature switch 70 is preferably two groups of temp control switch elements, and one of which is high temperature shutoff, and another group is low-temperature switch.First group of temp control switch element detects battery pack temperature when being high temperature, and first group of temp control switch element sends a unlatching signal, and conductor temperature regulation unit 30 starts to freeze to battery component 10.First group of temp control switch element detects battery pack temperature when being not high temperature, and conductor temperature regulation unit 30 stops refrigeration.Same reason, second group of temp control switch element detects battery pack temperature when being low temperature, and second group of temp control switch element sends a unlatching signal, and conductor temperature regulation unit 30 starts to heat to battery component 10.When battery pack temperature reaches determined temperature, stop heating.When conductor temperature regulation unit 30 is started working, the first cycling element 20 and the second cycling element 40 work simultaneously.When temperature switch 70 detects the temperature difference of battery component 10 within the specific limits, during such as 2 to 3 DEG C, temperature switch 70 sends temperature signal, and the only first cycling element 20 works, and the second cycling element 40 does not works.In another kind of better embodiment, the unlatching/closedown of temperature switch 70, or the unlatching/closedown of the first cycling element 20 can be controlled by external unit (such as Vehicular battery management system or manual operation).
