Technical Field
The utility model relates to a battery technical field especially relates to a power storage battery heating circuit.
Background
In a low temperature environment, the energy and power of the power storage battery are reduced, and the driving range and the dynamic performance of the vehicle are degraded. Therefore, the power storage battery needs to be heated, the temperature of the battery is increased, and the charging and discharging performance and the safety of the battery in a low-temperature environment are ensured. The heating system has the function of rapidly heating all monomer temperatures in the battery system to specific temperatures, and requires that the temperature difference between the monomers is not too large, the too large temperature difference can lead to poor monomer consistency, and further influences the service life of the power battery, the heating loop of the conventional power storage battery pack is a series loop, all power battery boxes must be uniformly opened or closed with heating functions, in a low-temperature environment, a large number of battery boxes are arranged, scattered commercial vehicles are arranged, the temperature difference between the battery boxes can be caused to be too large due to the influence of an external flow field of the vehicle, the phenomenon that the heating cannot be started is inevitable, a parallel heating loop is needed at present, the heating can be independently opened or closed according to the temperature condition of each battery box, the battery boxes can be heated as required, the temperature difference between the monomers can be eliminated, the heating energy is saved, and the problem that the battery boxes cannot be started due to the large temperature difference is solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a power storage battery heating circuit to prior art's not enough, thereby the temperature condition of having solved every battery box of prior art can't independently open or close the heating, heats the battery box as required, eliminates the inter-box monomer difference in temperature, practices thrift heating energy, solves the problem that can't start because of the difference in temperature heats greatly.
The utility model discloses an adopt following technical scheme to realize:
the utility model provides a power storage battery heating circuit, includes main loop switch, battery box, heating film, battery box heating contactor, the positive contactor of heating, heating negative contactor, charges and inserts the main loop after the main loop switch is established ties, and is a plurality of the battery box with the main loop switch is established ties, and is a plurality of be provided with temperature sensor in the battery box respectively, and is a plurality of be provided with respectively in the battery box the heating film, after the heating film is parallelly connected with the positive contactor of heating with the heating negative contactor is established ties and is inserted the main loop, charge positive contactor with the negative contactor that charges inserts the main loop respectively.
Preferably, each of the heating membranes is connected in series with the battery box heating contactor.
Compared with the prior art, the utility model discloses following profitable technological effect has:
the parallel heating loop can independently control the on-off of the heating of each battery box, and heats the battery boxes as required; the problem of the monomer difference in temperature between the case, heating energy is practiced thrift, heating can't start because of the difference in temperature is big is solved.
