The utility model content
The technical problems to be solved in the utility model is, a kind of lithium ion battery group that still can operate as normal under the low temperature environment temperature is provided.
Technical solution of the present utility model is, a kind of lithium ion battery group with following structure is provided, and it comprises monocell, battery management system and housing, and described monocell and battery management system are installed in the described housing; Described battery management system comprises central controller and temperature control device of vehicle, described temperature control device of vehicle comprises phase-change material and heat carrier, described heat carrier is wrapped in outside the described monocell, described phase-change material is filled in the space between described monocell and the described housing, described temperature control device of vehicle also comprises heater, described heater is embedded in the described phase-change material and with described heat carrier and contacts, and described heater is electrically connected with described central controller.
After adopting above structure, the utility model lithium ion battery group compared with prior art has the following advantages:
Because the utility model lithium ion battery group also comprises heater, described heater is embedded in the described phase-change material and with described heat carrier and contacts, described heater is electrically connected with central controller, but the lithium ion battery group is in the low temperature environment, the working temperature of monocell is lower than the following of its normal working temperature and prescribes a time limit, central controller can be controlled heater and begin heating by it, the heat that produces during the heater heating can conduct to monocell by heat carrier, at this moment, the working temperature of monocell can slowly rise, when the working temperature of monocell rises to its normal working temperature, central controller is just controlled heater and is stopped heating by it, the working temperature for the treatment of monocell is lower than its normal working temperature again following in limited time, heater begins heating again, so periodic duty, make that the lithium ion battery group still can operate as normal under the ambient temperature of low temperature, thereby can keep the performance of lithium ion battery and the useful life of guaranteeing lithium ion battery.
As a kind of improvement of the present utility model, described heater is a heater strip.Heater strip is general and cost is low, and heater strip can be reduced cost as heater.
As another kind of improvement the of the present utility model, described heater has four, and described four heaters lay respectively at the front, rear, left and right side of described heat carrier.Because described heater has four, lays respectively at the front, rear, left and right side of heat carrier, this kind structure can make its operate as normal so that the monocell in the lithium ion battery group is heated evenly.
