The system solves the problems that the power battery is low in discharging efficiency and long in charging time due to poor low-temperature characteristic.
Description
Technical field
The utility model belongs to battery technology field, particularly a kind ofly to power battery box, carry out pre-warmed system.
Background technology
Along with the global energy crisis day by day closing on, the New-energy electric vehicle of energy-conserving and environment-protective has progressively entered people's life, becomes a kind of trend of future life.But the characteristic of current driving force battery has restricted the significantly popularization of electric automobile, and electrokinetic cell low-temperature characteristics is poor, and discharging efficiency is low, and the charging interval is long, and these are all restricting using of electric automobile and are developing.
Utility model content
The technical problem existing in order to solve above-mentioned background technology, the utility model aims to provide and a kind ofly to power battery box, carries out pre-warmed system, thereby solves because electrokinetic cell low-temperature characteristics is poor, and the problem that the discharging efficiency causing is low, the charging interval is long.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is:
To power battery box, carry out a pre-warmed system, comprise Vehicular charger and power battery box, the inside of Vehicular charger is provided with control system, and electrokinetic cell is housed in power battery box.In power battery box, also comprise resistive heater, temperature collect module and main contactor.Described main contactor comprises an input and normally opened contact output and normally-closed contact output, Vehicular charger comprises the first charging end and the second charging end, the positive pole of electrokinetic cell connects the normally opened contact output of main contactor, the negative pole of electrokinetic cell connects the first charging end of Vehicular charger, one end of resistive heater connects the normally-closed contact output of main contactor, the other end of resistive heater connects Vehicular charger the first charging end, the second charging end of Vehicular charger connects the input of main contactor, the control system of Vehicular charger inside is controlled the work of temperature collect module and main contactor.
Wherein, said temperature acquisition module adopts DS18B20 digital temperature sensor.
The beneficial effect that adopts technique scheme to bring is:
Utilize the control system of Vehicular charger inside, by temperature in the heating maintenance electrokinetic cell casing of temperature collect module and control resistive heater, it is constant value, improve charging ability and the discharge capability of electric automobile power battery, guarantee that no matter electric automobile is in winter or summer, there are enough flying powers in the south still north.
Accompanying drawing explanation
Fig. 1 is system configuration schematic diagram of the present utility model.
Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is elaborated.
System configuration schematic diagram of the present utility model as described in Figure 1, a kind ofly carries out pre-warmed system to power battery box, comprises Vehicular charger and power battery box, and the inside of Vehicular charger comprises and is provided with control system, and electrokinetic cell is housed in power battery box.In power battery box, also comprise resistive heater, temperature collect module and main contactor.Described main contactor comprises an input and normally opened contact output and normally-closed contact output, Vehicular charger comprises the first charging end and the second charging end, the positive pole of electrokinetic cell connects the normally opened contact output of main contactor, the negative pole of electrokinetic cell connects the first charging end of Vehicular charger, one end of resistive heater connects the normally-closed contact output of main contactor, the other end of resistive heater connects Vehicular charger the first charging end, the second charging end of Vehicular charger connects the input of main contactor, the control system of Vehicular charger inside is controlled the work of temperature collect module and main contactor.
In this example, described temperature collect module adopts DS18B20.
Operation principle of the present utility model is: when user connects after civil power to Vehicular charger, the control system of Vehicular charger inside gathers electrokinetic cell the temperature inside the box by DS18B20, judge that whether temperature is lower than the threshold value of setting, if lower than threshold value, control system is just controlled main contactor and is disconnected normally-closed contact, closed normally opened contact, Vehicular charger is to resistance wire energising heating, treat that the temperature in power battery box reaches the low temperature threshold value of setting, and the temperature in confirmation battery case no longer changes, the normally opened contact that control system is controlled main contactor disconnects, normally-closed contact is closed, Vehicular charger is power battery charging, after to be charged completing, Vehicular charger internal control system gathers the temperature in battery case again, if lower than low temperature threshold value, main contactor normally-closed contact disconnects, normally opened contact is closed, be switched to pre-warmed state, keep the temperature in power battery box.
Above embodiment is only explanation technological thought of the present utility model; can not limit protection range of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection range.
