However, when the battery pack is in a severe cold environment and the outdoor temperature is below-20 ℃ or even below-30 ℃, the battery pack cannot be awakened normally due to low temperature, so that the electric equipment cannot operate at all. Therefore, solving the problem of battery wake-up under extreme cold conditions (below-25 ℃) is a technical problem to be solved urgently by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a battery package awakens up auxiliary heating system to realize that the battery package is awaken up in the assistance under the low temperature environment, ensure that equipment normally works.
The utility model discloses an above-mentioned problem is solved to following technical means: the utility model provides a battery package awakens up auxiliary heating system, includes battery package, water-cooling radiating element, heater, dc-to-ac converter and battery, the heater concatenates in the water-cooling radiating element and is used for the heating of cooling water, electricity is connected between battery, dc-to-ac converter and the heater.
Further, the heater is equipped with a plug.
Further, the heater is equipped with a plurality of stages.
Further, still include battery management unit, battery management unit is connected with inverter, heater and battery package electricity.
Further, the water-cooling heat dissipation unit is equipped with a water temperature sensor, and the water temperature sensor is electrically connected with the battery management unit.
Further, the storage battery is a low-voltage storage battery resistant to low temperature.
The utility model has the advantages that:
the utility model discloses a battery package awakens up auxiliary heating system, utilize the low pressure type battery of low temperature resistant can be under low temperature environment the good performance of normal work, through the power supply of battery contravariant, the starting heater, make the temperature rise, through the electric core heating of hot-water flow to the battery package, after heating to the battery package can normally awaken up, heating film heating mode can be opened to battery package self, therefore realized that the battery package is awaken up in the assistance of low temperature environment, the difficult technical problem that can't awaken up under the extremely cold condition of high-voltage battery package has been solved well to the mode of this kind of two-stage heating, make the electric equipment application scene more extensive. In addition, the heater can also be started by externally connecting a plug with a mains supply, so that the energy consumption of the storage battery is reduced.
