Abstract
The utility model discloses a heat management system for a power battery, which comprises a battery frame, wherein a battery assembly consisting of multiple battery units is arranged in the battery frame, a silica gel heating belt is glued between the battery frame and the battery assembly, and the silica gel heating belt is electrically connected with a heating belt controller. The heat management system for the power battery also comprises a battery management system for timely monitoring the temperature and the voltage of the battery assembly, and the heating belt controller is electrically connected with the battery management system. The heating is carried out by adopting the silica gel heating belt, thus the defects of low efficiency and high energy consumption of the traditional external circulating heating are overcome, the battery assembly and the battery frame are heated directly, uniformly and rapidly, thus energy of a battery electric vehicle power battery is effectively saved; the silicon gel heating belt is wide in working temperature, long in service life, small in occupation and is waterproof; and the silicon gel heating belt can also play a role in buffering impact of the battery.
Description
Technical field
The utility model relates to battery temperature and regulates the field, relates in particular to a kind of electrokinetic cell heat management system.
Background technology
Automobile batteries; Especially pure electric automobile battery, temperature is lower than that battery is normal to be used when temperature required in the winter time, and the energy content of battery can reduce rapidly along with the reduction of outdoor temperature; Dump energy often is not enough to drive the automobile operate as normal; Electric automobile in this case, can shorten battery life especially, so will need carry out preheating to recover its energy content of battery to its storage battery in operate as normal under the low temperature environment.
At present; The battery of general-utility car is heated to be traditional air-cooled (heat) or water-cooled (heat) mechanism, is all the outer circulation pre-heating system, and the external heat device is through the outside cold heat transfer medium of heating; Inner to battery frame through outer loop heat transferred, battery is carried out preheating.Wherein heat transfer medium (air or cooling fluid) has absorbed great amount of heat the efficiency of heating surface is reduced greatly, and programming rate is become slowly, and has reduced efficient and also increased power consumption; For aforesaid drawbacks, the inner heating system of a lot of units technological development, as: at Chinese patent CN201120180344; Disclose the heating film device that a kind of use can stick in a kind of battery heating device, can be attached on the battery, directly battery has been heated; But general heating film working temperature is narrow, and is even inadequately, and heating-up temperature changes greatly; Life-span is shorter, and is easy to wear, and water proofing property is bad.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of the utility model is to propose a kind of electrokinetic cell heat management system that is used for the convection circulation of battery frame internal heat.
The purpose of the utility model will be achieved through following technical scheme:
A kind of electrokinetic cell heat management system comprises battery frame, and the battery pack of being made up of a plurality of battery cells is set in the said battery frame, is pasted with the silica gel heating tape between said battery frame and the battery pack, and said silica gel heating tape is electrically connected with the heating tape controller; Also comprise being used for monitoring in real time the temperature of said battery pack and the battery management system of voltage, said heating tape controller is electrically connected with battery management system.
Preferably; Above-mentioned a kind of electrokinetic cell heat management system; Wherein: be provided with at least two battery pack in the said battery frame, be pasted with a said silica gel heating tape between each battery pack and the said battery frame respectively, the parallel connection back is electrically connected with said heating tape controller between the said silica gel heating tape.
The outstanding effect of the utility model is: the electrokinetic cell heat management system of the utility model adopts the silica gel heating tape to overcome the shortcoming of traditional outer circulation heating poor efficiency high energy consumption; Battery pack and battery frame are heated; Carry out the thermal convection circulation through the battery frame inner air; Heating directly, evenly, rapidly, firing rate is effectively saved the energy of pure electric automobile electrokinetic cell than with 2 ~ 3 times of the outer circulation heat blocks of power; Silica gel heating tape working temperature is wide, the life-span long, take up room little and waterproof; Buffering can also be worked to collide to battery in the silica gel heating tape.
Following constipation closes the embodiment accompanying drawing, the embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the schematic diagram of the utility model embodiment.
Embodiment
Embodiment:
A kind of electrokinetic cell heat management system of present embodiment; Like Fig. 1～shown in Figure 2; Comprise battery frame 1; The battery pack 3 and battery pack 4 be made up of a plurality of battery cells 2 are set in the battery frame 1, are pasted with silica gel heating tape 5 and silica gel heating tape 6 between battery pack 3 and battery pack 4 and the battery frame 1 respectively, the parallel connection back is electrically connected with the heating tape controller between silica gel heating tape 5 and the silica gel heating tape 6.Also comprise being used for monitoring in real time battery pack 3 and the temperature of battery pack 4 and the battery management system of voltage, the heating tape controller is electrically connected with battery management system.Through the Voltage Feedback and the Temperature Feedback of battery management system, heating tape controller control silica gel heating tape 5 and silica gel heating tape 6 opening and closing separately, and heating power.
The electrokinetic cell heat management system of present embodiment adopts the silica gel heating tape to overcome the shortcoming of traditional outer circulation heating poor efficiency high energy consumption; Battery pack and battery frame are heated; Carry out the thermal convection circulation through the battery frame inner air; Heating directly, evenly, rapidly, firing rate is effectively saved the energy of pure electric automobile electrokinetic cell than with 2 ~ 3 times of the outer circulation heat blocks of power; Silica gel heating tape working temperature is wide, the life-span long, take up room little and waterproof; Buffering can also be worked to collide to battery in the silica gel heating tape.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection range of the utility model.
