Description
Technical field
The utility model belongs to electric automobile energy and reclaims field, and particularly a kind of electric energy that can directly braking energy be reclaimed is applied to the system of battery system heating.
Background technology
Lithium-ion-power cell, with its excellent cycle characteristics, high specific energy density, specific power density, becomes current most study electric powered motor power supply.But the low temperature capacity characteristic of rear lithium ion battery group is poor in groups, it is also one of obstacle of Development of Electric Vehicles.For addressing this problem, a large amount of work has all been done by each car load Chang Ji Battery Plant, comprise design motivation battery preheating heating system, improve battery material, battery system is done to insulation heating arrangement, but effect is all not ideal.Electronlmobil has a lot of energy not to be utilized in the braking procedure travelling, and existing brake energy recovering system is because the path of transformation of energy is grown and caused energy recovery rate lower.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of system that can heat lithium ion battery group, and the power delivery that braking energy is reclaimed is battery system heating to battery heating device, improves the low temperature course continuation mileage of electronlmobil.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of electrokinetic cell heating system that improves electronlmobil low temperature course continuation mileage, comprise electrical generator, inverter, battery box, in battery box, be provided with lithium ion battery group, in battery box, be also provided with temperature booster, the mouth of electrical generator connects inverter, and the mouth of inverter connects temperature booster and lithium ion battery group.
Preferably, temperature booster detouchable is installed in battery box, is closely set in the bottom surface of lithium ion battery group.
Preferably, also comprise single machine unit, single machine unit is connected with temperature booster with electrical generator, inverter, lithium ion battery group respectively by CAN bus.
Preferably, also comprise the auxiliary energy storage unit that is connected in inverter, auxiliary energy storage unit is connected with single machine unit by CAN bus.
Preferably, auxiliary energy storage unit is storage battery or cond.
The beneficial effects of the utility model are braking energy to be converted to electric energy by electrical generator collect afterwards, to battery pack or stand by battery power supply, and realize to battery pack the heating function under low-temperature condition by being arranged on the temperature booster of battery pack, reclaim the low-temperature properties that braking energy improves lithium ion battery group, also improved the low temperature course continuation mileage of electronlmobil simultaneously.Charging the battery or the charging of auxiliary storage battery of the energy selectivity that braking energy is reclaimed, thus make battery pack be operated in environmental optima, extend low temperature course continuation mileage and the service life of electronlmobil.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment system architecture schematic diagram
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of electrokinetic cell heating system that improves electronlmobil low temperature course continuation mileage of the present embodiment comprises electrical generator, inverter, battery box as shown in Figure 1, in battery box, be provided with lithium ion battery group, in battery box, be also provided with temperature booster, the mouth of electrical generator connects inverter, and the mouth of inverter connects temperature booster and lithium ion battery group.Temperature booster detouchable is installed in battery box, is closely set in the bottom surface of lithium ion battery group.Also comprise single machine unit, single machine unit is connected with temperature booster with electrical generator, inverter, lithium ion battery group respectively by CAN bus.Also comprise the auxiliary energy storage unit that is connected in inverter, auxiliary energy storage unit is connected with single machine unit by CAN bus, the auxiliary energy storage unit of the present embodiment is preferably storage battery or cond, in lithium ion battery group, be also provided with the temperature booster that is connected in inverter and single machine unit, temperature booster detouchable is installed in lithium ion battery group, receive through inverter and transform the electric energy of coming, by single machine unit, controlled, in Fig. 1, dotted line is CAN bus.
Because temperature booster is detouchable, when electronlmobil Han district is used, can attach it in power brick, and when electronlmobil is used under the higher environment of corresponding temperature, its dismounting can not affected to the heat radiation of battery itself.Single machine unit and lithium ion battery group and temperature booster, auxiliary energy storage unit are by forceful electric power line parallel join, by CAN bus and energy conversion unit, inverter, auxiliary energy storage unit, lithium ion battery group, heating of battery unit connects, and can control discharging and recharging of lithium ion battery group and auxiliary energy storage unit, and monitors the state-of-charge information of the information such as the interior battery temperature of lithium ion battery group, voltage, electric current, state-of-charge (SOC) and auxiliary energy storage unit.The system providing by the present embodiment, can be used for recovery braking energy to improve the low-temperature properties of lithium ion battery group, has also improved the low temperature course continuation mileage of electronlmobil simultaneously.It is battery system heating that the electric energy that braking energy reclaims can directly flow to battery heating device, and auxiliary energy storage unit also can directly provide the mechanical energy of driving for automobile in addition, for heating of battery unit provides electric energy.When electronlmobil cold-starting, lithium ion battery group also can be directly for heating of battery unit provides electric energy.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
