Abstract
The invention discloses a thermal management system for a power battery, which comprises a battery frame. A battery pack which consists of a plurality of battery units is arranged in the battery frame; a silica gel heating tape is attached between the battery frame and the battery pack; and the silica gel heating tape is electrically connected with a heating tape controller. The thermal management system for the power battery also comprises a battery management system used for performing real-time monitoring the temperature and the voltage of the battery pack; the heating tape controller is electrically connected with the battery management system. According to the thermal management system for the power battery, the disadvantages that the efficiency is low and the consumption is high by adopting traditional outer circulation heating are overcome by adopting the silica gel heating tape; the battery pack and the battery frame are heated directly, evenly and rapidly, and thereby, the energy of the power battery of a pure electromobile is effectively saved; the silica gel heating tape is wide in working temperature, is long in service life and is small in occupied space and is waterproof. The silica gel heating tape is also capable of performing a collision buffering action on the battery.
Description
Technical field
The present invention relates to battery temperature and regulate the field, relate 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.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of electrokinetic cell heat management system that is used for the convection circulation of battery frame internal heat.
The object of the invention 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.
Outstanding effect of the present invention is: electrokinetic cell heat management system of the present invention 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, and specific embodiments of the invention is done further to detail, so that technical scheme of the present invention is easier to understand, grasp.
