Abstract
The utility model provides a heating device of an electric car storage battery from inside to outside. The heating device is characterized in that the heating device is wound on leading-out terminals of the cathode and the anode of the storage battery, a heating circuit is arranged in the heating device, and the heating device is connected with a power supply through a power supply outgoing line. The heating device of the storage battery adopts the thinking that heating is performed at the positions of the leading-out terminals of the cathode and the anode and heats through a heat transmission mode. Specifically, for improving heat transmission effects, the heating device is installed at the positions of the leading-out terminals of the cathode and the anode of a monomer battery. Due to the fact that the leading-out terminals of the cathode and the anode of the battery are generally made of pure copper, pure nickel, pure aluminum and the like, heat transmission performance of the materials is excellent, heating efficiency of the battery is improved remarkably.

Background technology
In recent years, under the background of advocating the low-carbon green environmental protection, the air pollution that the tail gas of motor vehicles discharging causes had become a global difficult problem.A kind of solution route of this difficult problem is with the electric power of the zero discharge power as motor vehicles, and such as electric automobile, hybrid vehicle, they receive increasing the concern and development.Therefore the exploitation of car battery also more and more is taken seriously.
And car battery charge-discharge characteristic at low temperatures is relatively poor, when moving in the winter time, discharging and recharging power significantly reduces, the Acceleration of starting ability significantly reduces, charge in this case or heavy-current discharge, not only have a strong impact on the life-span of battery, for lithium ion battery, also might because the low temperature charging causes negative terminal surface precipitating metal lithium, cause the serious safety problems such as short circuit, burning even blast.Therefore taking temperature to the method rising storage battery of storage battery heating is present main solution.
; the car battery that is widely used at present; such as Ni-MH battery, lithium ion battery; its general heating measure is that several point setters are set in battery case; battery unit by the whole battery case of radiation heating; battery cell temperature near heater can be high, and the battery cell temperature of other positions can be low.The method of heating generally is the heating from outside to inside in addition, and such as the heating collar heating, these heating means not only affect the effect of heating, the efficiency of heating surface is lower, time is longer, also can make each battery unit formation temperature poor, thereby affects normal operation and the life-span of battery.
The utility model content
The purpose of this utility model is to provide a kind of heating device for storage battery of from-inner-to-outer, to improve the effect of storage battery heating.
The heater that the utility model provides is in the both positive and negative polarity leading-out terminal position of storage battery heater to be installed to heat.Because the both positive and negative polarity leading-out terminal of battery generally is fine copper, pure nickel, fine aluminium etc., the heat-conductive characteristic comparative superiority of these materials, other positions of the battery of comparing, it is high a lot of that the heat transfer efficiency of both positive and negative polarity leading-out terminal is wanted.
The related heater of the heating thinking that the utility model relates to is not only applicable to cylindrical battery, applicable to square battery yet, also applicable to the peculiar flexible-packed battery of lithium ion, can be cell, can be the power brick of any compound mode yet.
The related heater of heating thinking that the utility model relates to, the problem that needs to consider comprises heating uniformity, battery insulation, heating power and efficient and firing rate etc.As shown from the above technical solution, the utility model is by superscribing the heater with heating function at battery plus-negative plate leading-out terminal position, can make storage battery in its battery temperature is lower than the scope of normal working temperature, even in the situation that vehicle can't start, about ten minutes, be heated to normal operating temperature range, thereby can make normal vehicle operation, the utility model is to battery body or to the material of single battery cell, guarantee homogeneous heating, use safety, the efficient of insulation and heating is higher.
The surface that described heater can adopt the heating mantle to twine the both positive and negative polarity leading-out terminal that is attached to battery makes the heating mantle with the both positive and negative polarity leading-out terminal good contacting be arranged, thereby can improve the efficient of conducting heat when heating; Equally, also can adopt heater strip directly to be wrapped in the surface of battery plus-negative plate leading-out terminal.
Can to be that multiple high temperature resistant organic material, macromolecular material, carbon element and high-temperature fibre are compound make novel thermo electric material to the material of described heating, this heating film have softness, folding, corrosion-resistant, heating is fast, heating is even, energy-conservation, insulation, ventilative etc. advantage, or metal heating wire.
In sum, the utility model provides a kind of heater of accumulator of electric car of from-inner-to-outer, comprise the heater that is wound in the accumulator anode and cathode leading-out terminal, be provided with heater circuit in the described heater, this heater links to each other with power supply by power outlet.The storage battery mode of heating that the utility model provides, employing is in the thought of both positive and negative polarity leading-out terminal position heating, heat by heat conducting mode, particularly, in order to improve heat-transfer effect, in the both positive and negative polarity leading-out terminal position of cell heater is installed, because the both positive and negative polarity leading-out terminal of battery generally is fine copper, pure nickel, fine aluminium etc., the heat-conductive characteristic comparative superiority of these materials, the efficiency of heating surface of battery obviously improves like this.When battery pack was heated, the circuit that only need heat carried out connection in series-parallel according to the compound mode of battery and gets final product, but must note insulation, avoids battery short circuit.
Related storage battery heating thought is method from inside to outside, begun both positive and negative polarity leading-out terminal position preferably by the battery heat conductivility, rather than in heating means from outside to inside such as the outside of battery dress heating films, the efficient of heating is greatly improved like this, and heating is more even.The temperature of battery management system BMS Real-Time Monitoring battery body, and output control signals to temperature controller, temperature controller heats or stopped heating heater after receiving this control signal.
