Abstract
The utility model relates to a battery pack for electric automobiles, which comprises an air inlet pipe, a battery pack body, an electric heating PTC and a control system. A battery management system is arranged in the battery pack body; the control system is connected with the battery management system; and the electric heating PTC is respectively connected with the control system, the air outlet of the air inlet pipe and the air inlet end of the battery pack body. The battery pack has the advantage that the problem that the battery pack can not supply power to an electric automobile because the environmental temperature is too lower is avoided.
Description
[technical field]
The utility model relates to a kind of power brick, relates in particular to a kind of power brick of used for electric vehicle.
[background technology]
The power brick that ferric phosphate lithium cell constitutes can be used as the power brick of used for electric vehicle, and its operating temperature range generally is-20 ℃-60 ℃.And under normal conditions; When residing regional Yin Wendu is low excessively when causing temperature in the power brick to be lower than 0 ℃; Charger can be forbidden battery is charged with the protection battery; Thereby make power brick to discharge and recharge, and then cause electric automobile can't use and go at low temp area to electric automobile.
[utility model content]
The utility model technical problem to be solved is to provide a kind of power brick of used for electric vehicle, avoids crossing the problem that the low power brick that causes can't discharge and recharge for electric motor car because of ambient temperature.
The utility model solves the problems of the technologies described above through following technical scheme: a kind of power brick of used for electric vehicle; Comprise an air inlet pipe, a power brick main body, an electric heating PTC, reach a control system; Be provided with a battery management system in the said power brick main body; Said control system is connected with battery management system, and said electric heating PTC is connected respectively with the gas outlet of control system, air inlet pipe and the inlet end of power brick main body.
Further, also comprise at least one extractor fan that is connected with battery management system, said extractor fan all is located at the place, outlet side of power brick main body.
Further, said control system is integrated on the battery management system.
Further, said electric heating PTC is located between the inlet end of gas outlet and power brick main body of air inlet pipe.
Further, be provided with at least one screen pack in the said air inlet pipe.
The beneficial effect of the power brick of a kind of used for electric vehicle of the utility model is:
1, the setting of electric heating PTC and control system; When ambient temperature is low excessively when causing temperature in the power brick main body to be lower than 0 ℃; Opening electric heating PTC through control system heats the air-flow that gets into the power brick main body; Temperature in the power brick main body is raise, thereby can avoid crossing the problem that the low power brick that causes can't discharge and recharge for electric motor car, and then electric automobile can normally be used at low temp area go because of ambient temperature;
2, set up extractor fan in the outlet side of power brick main body, can guarantee that heat can evenly distribute in power brick, and keep the ventilation of power brick;
3, the design of air inlet pipe inner filtration net can be filtered the purpose with the purification that reaches removal of impurities to the air-flow that gets in the air inlet pipe.
[description of drawings]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.
Fig. 1 is the sketch map of the power brick of a kind of used for electric vehicle of the utility model.
[embodiment]
See also Fig. 1; The power brick of a kind of used for electric vehicle of the utility model; Comprise an air inlet pipe 1, a power brick main body 2, an electric heating PTC 3 (wherein PTC is the english abbreviation of thermistor), and one be used to control the control system (not shown) that electric heating PTC 3 opens or closes; Be provided with a battery management system (not shown) in the said power brick main body 2; Said control system is connected with battery management system (BMS), and said electric heating PTC 3 is connected respectively with the gas outlet 11 of control system, air inlet pipe 1 and the inlet end 21 of power brick main body 2.In the present embodiment; Can in the power brick main body, evenly distribute in order to ensure heat; And the ventilation that keeps power brick, be provided with the extractor fan 4 that is connected with battery management system at 22 places, outlet side of power brick main body 2, and the quantity of this extractor fan 4 can be adjusted according to the time needs; In order to make the entire cell bag more compact attractive in appearance, the applicant is integrated in control system on the battery management system, and is located at electric heating PTC 3 between the inlet end 21 of gas outlet 11 and power brick main body 2 of air inlet pipe 1; In addition, for the air-flow that will get into from the air inlet 12 of air inlet pipe 1 filters the purpose with the purification that reaches removal of impurities, in air inlet pipe 1, be provided with at least one screen pack 5.
The utility model is in the process that is charging electric vehicle; When the battery management system in the power brick main body 2 (BMS) monitors temperature in the power brick main body 2 when being lower than 0 ℃; Charger will stop battery being charged; Battery management system this moment (BMS) sends the heating instruction through control system to electric heating PTC 3, and opens extractor fan 4, makes 3 pairs of air-flows that come out from the gas outlet 11 of air inlet pipe 1 of electric heating PTC add the thermosetting thermal current; Thermal current gets into power brick main body 2 through inlet end 21 afterwards; And extractor fan 4 will get into the direction of thermal current from inlet end 21 toward outlet side 22 of power brick main body 2 and take out (soon air-flow is extracted into the rear portion from the front portion of power brick main body 2), make the temperature in the power brick main body 2 can be higher than 0 ℃, to guarantee the charging of charger to battery; Generally speaking, when monitoring can send electric heating PTC 3 through control system when temperature in the power brick main body 2 reaches 20 ℃, the battery management system in the power brick main body 2 (BMS) stops the heating instruction.
To sum up; When ambient temperature is low excessively when causing temperature in the power brick main body to be lower than 0 ℃; Opening electric heating PTC through control system heats the air-flow that gets into the power brick main body; Temperature in the power brick main body is raise, thereby can avoid crossing the problem that the low power brick that causes can't be supplied power for electric motor car, and then electric automobile can normally be used at low temp area go because of ambient temperature.
