Background technology
In recent years, pure electric automobile has the plurality of advantages such as energy-saving and environmental protection, and along with the minimizing increasingly of the energy, country greatly develops electric automobile industry.For electric automobile, owing to instead of engine with motor, so the energy resource system of fuel vehicle certainly will will change to adapt to electric automobile.And the refrigeration of high-tension battery bag and heat the ability to work being related to battery pack, there is vital effect to the Power output of car load and energy input efficiency.In the winter time, charging interval and charge capacity receive the restriction of ambient temperature to power brick significantly.Think under the condition of winter or cold that the optimum working temperature of real-time ensuring battery is very inaccessible.At present, conventional heating means are by heating battery ambient air, make the temperature of battery increase, but heating power is limited, heated perimeter is little, and heating time is longer, the charging interval can be caused to extend, underfill thus affect continual mileage within the charging interval of presetting.When each battery pack temperature in same battery case and inconsistent time, only cannot heat for the battery pack that temperature is low, cause the waste of the energy.
Battery management system (BATTERYMANAGEMENTSYSTEM, BMS) is the tie between battery and user, and main object is secondary cell.There are some shortcomings below in secondary cell, as few in stored energy, the life-span is short, connection in series-parallel uses problem, safety in utilization, battery electric quantity estimation difficulty etc.The performance of battery is that very complicated, dissimilar battery behavior also differs greatly.Battery management system (BMS) is exactly mainly the utilance in order to improve battery, prevents battery from occurring overcharging and over-discharge can, extends the useful life of battery, the state of monitoring battery.Along with the development of battery management system, other function also can be increased.
Summary of the invention
The object of this invention is to provide a kind of batteries of electric automobile bag charging heating device.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of batteries of electric automobile bag charging heating device, comprise heating chamber and the high-tension battery case of at least one, described heating chamber is built with recirculated water and the heating module for heating described recirculated water, described heating chamber to be communicated with described high-tension battery case by outlet pipe and return pipe and to form water-flow circuit, and described outlet pipe is provided with circulating pump; A plurality of high-tension battery modules is comprised in described high-tension battery case, temperature sensor is equipped with in each described high-tension battery module, each described high-tension battery module includes water inlet and delivery port, described water inlet and water outlet are respectively equipped with a selectivity opening and closing electromagnetically operated valve, and described selectivity opening and closing electromagnetically operated valve, described temperature sensor are all connected with BMS Systematical control by control circuit with described heating module.
Further, described heating module is electrically connected with driving power by power supply circuits, described driving power comprise in DC-DC, low tension battery and charging inlet one or more.
Further, described outlet pipe is wrapped with the thermal insulation layer for preventing heat losses.
Further, described return pipe is wrapped with the thermal insulation layer for preventing heat losses.
Further, described heating module is the resistive heater with water-proof function.
Compared with prior art, the beneficial effect of a kind of batteries of electric automobile bag charging heating device of the present invention is:
The present invention passes through water-flow circuit, utilize oven heats recirculated water, thus high-tension battery module is heated up, overcome directly less by specific heat capacity air conduction and do not cause heating effect good and heat the little defect of scope, adding the utilance of heater simultaneously.When confirming to start to charge, BMS system is according to the temperature of the high-tension battery module obtained by temperature sensor, determine whether starting heating module, and determine whether control the circulation waterway that selectivity opening and closing electromagnetically operated valve opened separately or cut out corresponding high-tension battery module, thus optionally make recirculated water pass through to need the high-tension battery module of heating, play the effect of efficiency utilization recirculated water.The invention solves electric automobile mesohigh power brick and cause the phenomenon even cannot charged slowly of charging because temperature is too low; Compact conformation, takes up room little, can use on large, medium and small all kinds of electric automobile; Good working effect, easy to operate, safety; Thermal-stable is good, system highly versatile.
