Description
Technical field
The utility model relates to battery-driven car power source technical field, is specifically related to a kind of Electrical Bicycle power source storage battery cryogenic temperature charging system.
Background technology
Electrical Bicycle leans on its characteristics such as economic and light to win consumers in general's favor.Yet the power source storage battery of battery-driven car especially under low temperature condition, can cause the activity of lead-acid battery both positive and negative polarity pole plate material to descend.At present, the most of valve-control sealed lead acid battery that adopts of battery-driven car, discharge under-10 ℃ of environment, capacity of negative plates is 35%, positive electrode capacity is 75%.The lead plaster of separating out on the negative pole becomes fine grain easily; Cause hole to be prone to freezed and stop up, stop ion exchange and electrochemical process, thereby make the resistivity of electrolyte increase; Particle carries electron diffusion speed to be reduced; Can cause the internal resistance of cell to increase, reduce battery discharge efficient, battery performance reduces.
The utility model content
To above-mentioned prior art, the utility model provides a kind of electromobile battery heating and heat-insulation system, can solve current driving force energy storage battery under the situation of low temperature, the problem that battery discharge efficient is low, battery performance reduces.
In order to solve the problems of the technologies described above; The technical scheme that heating of the utility model electromobile battery and heat-insulation system are achieved is: comprise the outer power supply source of battery case and 48V; Also comprise the electric hot plate and the temperature sensor T that all are electrically connected with a microprocessor; Said temperature sensor T is arranged in the said battery case, and the inwall of said battery case is provided with adiabator layer, and two lines between said microprocessor and the said electric hot plate are provided with source switch.
In addition, for the sake of security, outer power supply source of said 48V and the equal ground connection of said electric hot plate.
Compared with prior art, the beneficial effect of the utility model is:
Be provided with temperature sensor in the battery case of heating of the utility model electromobile battery and heat-insulation system; Be filled with adiabator layer efficiently in the box; And the battery case in-to-in ambient temperature after the heating being remained in the range of set temperature through intelligentized type of heating, its temperature retention time can remain on the time of setting.The normal working temperature that can actv. guarantees storage battery in the winter low temperature driving; Make storage battery can give play to dynamical capacity; Prolong the time of battery release current under low-temperature condition, thereby improved the travelled distance of Electrical Bicycle under cryogenic conditions, reach energy-conservation effect.
Description of drawings
Accompanying drawing is the structural representation sketch of heating of the utility model electromobile battery and heat-insulation system.
Among the figure:
The 1-storage battery, 2-battery case, 3-adiabator layer, 4-microprocessor, the outer power supply source of 5-48V, 6-electric hot plate, 7-source switch.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is done to describe in further detail.
Shown in accompanying drawing, heating of the utility model electromobile battery and heat-insulation system comprise the outer power supply source 5 of battery case 2 and 48V; It is characterized in that also comprise the electric hot plate 6 and temperature sensor T that all are electrically connected with a microprocessor 4, said temperature sensor T is arranged in the said battery case 2; Be used to detect battery case 2 interior environment temperature; The inwall of said battery case 2 is provided with adiabator layer 3, and the line between said microprocessor 4 and the said electric hot plate 6 is provided with source switch 7, and this source switch 7 is used for controlling the heating plate heating of the utility model; Outside two, the time spent is not closed the outer power supply source of heating plate through this source switch in summer.For the sake of security, outer power supply source 5 of said 48V and said electric hot plate 6 equal ground connection.
The principle of work of heating of the utility model electromobile battery and heat-insulation system is: because temperature sensor T is positioned in the battery case 2; Temperature sensor T will detect in the battery case 2 temperature signal send in the microprocessor 4; Microprocessor 4 is judged when the temperature signal that receives is lower than the lower limit of design temperature; Microprocessor 4 sends the control signal that makes electric hot plate 6 energising heating; When temperature signal was higher than the higher limit of design temperature, microprocessor 4 sent the control signal that makes electric hot plate 6 outages, stopped heating.The ambient temperature of the adiabator layer 3 that in battery case 2, is provided with in can the maintenance battery case 2 of long period is in a suitable scope; The normal working temperature that can actv. guarantees storage battery 1 in the winter low temperature driving; Make storage battery 1 can give play to dynamical capacity; Prolong the time of battery release current under low-temperature condition, thereby improved the travelled distance of Electrical Bicycle under cryogenic conditions, reach energy-conservation effect.
Although top combination figure is described the utility model; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Under the situation that does not break away from the utility model aim, can also make a lot of distortion, these all belong within the protection of the utility model.
