Abstract
The invention belongs to a temperature control system for a power battery pack of an electric vehicle, and in particular relates to the novel temperature control system for the power battery pack of the electric vehicle applied to the power battery pack of the electric vehicle. A solar panel covers a vehicle roof and is respectively connected with a storage battery and a DC-DC converter through a controller; the DC-DC converter is connected with a storage battery radiator; and a battery management system and the storage battery are connected with a battery management system respectively. The battery pack radiator of the invention starts to work by using the electric energy converted from solar energy, so the temperature of the solar pack is reduced to a normal range, the overall system converts the collected solar energy into the electric energy and completely stores the electric energy into the power battery pack; and therefore, the solar energy is effectively utilized.
Description
Technical field
The invention belongs to electric automobile power battery group temperature control system, particularly be applied to a kind of novel temperature control system for power battery pack of electric vehicle of electric vehicle dynamic cell group.
Background technology
Power battery pack is the important component part of electric automobile.Because in the charge and discharge process, battery itself can produce heat, cause temperature to rise, and electrokinetic cell is relatively more responsive to temperature environment, especially obvious as big capacity, the application of high power electrokinetic cell the time, too high or too low temperature all can influence charge-discharge performance and a lot of characterisitic parameter of battery, for example internal resistance, voltage, SOC, active volume, efficiency for charge-discharge and battery life greatly.The even charge-discharge performance and the life-span that also can influence battery pack of temperature distributing disproportionation.Therefore must make battery pack be in suitable temperature range, thereby improve performance and cycle life, and get rid of the potential hazard that causes because of thermal runaway.Particularly in the summer of sweltering heat, under burning sun, the influence that power battery pack is subjected to is bigger.The present invention is exactly a kind of novel temperature control system of exploitation, thereby power battery pack is maintained a suitable temperature range.
Summary of the invention
The purpose of this invention is to provide a kind of novel temperature control system for power battery pack of electric vehicle, form by solar panels, controller, DC-DC transducer, storage battery, storage battery radiator and battery management system, it is characterized in that solar panels cover roof, be used for collecting solar energy; Solar panels are connected with the DC-DC transducer with storage battery respectively by controller, the DC-DC transducer connects the storage battery radiator, power to radiator, the work state information of battery pack and radiator is also controlled the operating state of battery pack and radiator simultaneously by the battery management system collection by battery management system.
The energy acquisition and the power conversion of described controller control solar panels, and the operation of supervision whole system.
Described battery management system is used for supervising the work of battery pack and the state and the working temperature state of accumulator cell charging and discharging.
The invention has the beneficial effects as follows that the battery pack radiator utilizes the electric energy of solar energy converting to start working, make battery pack temperature be reduced to normal range (NR), whole system then becomes the solar energy converting of gathering electric energy and deposits power battery pack fully in, effectively utilizes solar energy.
Description of drawings
Fig. 1 is the novel temperature control system for power battery pack of electric vehicle schematic diagram.

Embodiment
The invention provides a kind of novel temperature control system for power battery pack of electric vehicle.Figure 1 shows that the novel temperature control system for power battery pack of electric vehicle schematic diagram.Solar panels 1 cover roof among the figure, are used for collecting solar energy; Solar panels 1 are connected with DC-DC transducer 3 with storage battery 6 respectively by controller 2, and DC-DC transducer 3 connects storage battery radiator 5, and battery radiator 5 storage batterys 6 integrate; Battery management system 4 is connected with storage battery, storage battery radiator 5 respectively.Storage battery is used for storage of electrical energy; The storage battery radiator is used for distribute heat.
Concrete working condition is as follows, be electric energy with solar energy converting at first by solar panels, when the temperature of battery pack is too high, the battery pack radiator utilizes the electric energy of solar energy converting to start working, be the battery pack heat radiation, unnecessary electric energy can be stored in the power battery pack, when battery pack temperature is reduced to normal range (NR), whole system then becomes the solar energy converting of gathering electric energy and deposits power battery pack fully in, and fundamental diagram is seen Fig. 2.
