Abstract

The invention discloses a battery protector. The battery protector comprises a box body and an electric heating device, wherein the box body is provided with a box bottom (1), a box top (2), box walls (3) and a box door (4), the electric heating device is arranged in the box body, is electrically connected with a power supply device and is a carbon fiber electric heating body (6), and the outer layer of the carbon fiber electric heating body (6) is coated with an insulation heat conduction layer (5). Compared with the prior art, the battery protector has the advantages that a battery can be protected to normally work in cold winter; particularly, the temperature in the box body can be enabled to be in a range suitable for battery starting all the time only by placing the battery in the battery protector and starting the electric heating device to heat, and the battery still can be enabled to normally work even an external environment is very cold; meanwhile, the reason for employing the carbon fiber electric heating body is that the carbon fiber electric heating body has thermal conversion efficiency which cannot be matched by that of an ordinary metal electrical heating body; the test shows that the heat conversion capability of a carbon fiber pipe is four times of the heat conversion capability of the ordinary metal electrical heating body, and the battery protector is very high in heat conversion capability; and moreover, the energy is saved, the power is saved, and the cost is lower.

Description

Storage battery protector

Technical field

The present invention relates to a kind of storage battery protector.

Background technology

At present, along with electric motor car popularity rate is increasingly wider, the storage battery of electric motor car was affected by cold in winter to be lost The problem of ability to work is more and more prominent, at present, there is no and a kind of storage battery can be protected in the cold winter Also the product that can normally work in it.

Summary of the invention

In view of this, the technical problem to be solved is: provide one that storage battery can be protected in cold Winter in the storage battery protector that also can normally work.

In order to achieve the above object, the present invention adopts the following technical scheme that and realizes:

A kind of storage battery protector, wherein, including having bottom, case top, tank wall and the casing of chamber door, also wraps Including the electric calorifie installation being electrical connected in being located at described casing with supply unit, described electric calorifie installation is external sheath There is the carbon fiber electrothermal part of thermal insulation layer.

As preferably, the end face of described bottom is concavely provided with caulking groove, and described carbon fiber electrothermal part is embedded at described In caulking groove.

As preferably, the end face upper cover of described bottom is pressed with heat-conducting plate.

As preferably, described carbon fiber electrothermal part is carbon fibre electrothermal wire or carbon fiber electric heating tube, described insulation Heat-conducting layer is Teflon, and described heat-conducting plate is steel plate.

As preferably, also include the control circuit being electrically connected between described electric calorifie installation and supply unit Plate, also includes that temperature sensor and heat abstractor, described heat abstractor include being opened in entering on described casing Gas port and gas outlet, the electric controlled door being located on described air inlet and gas outlet, the row that is located on described gas outlet Gas is fanned, and described temperature sensor, electric controlled door, exhaust fan are electrically connected at described control circuit plate and power supply dress Between putting.

As preferably, described air inlet is located on described tank wall, and described gas outlet is located on described case top.

As preferably, the electric controlled door on described gas outlet is positioned at the top of described exhaust fan.

As preferably, described chamber door is located on described tank wall or case top.

As preferably, described supply unit is external power source, battery, rechargeable battery or is placed in described Storage battery to be protected in casing itself.

As shown from the above technical solution, the invention has the beneficial effects as follows:

Compared to existing technology, the present invention can protect storage battery also can normally work in cold winter.Specifically For, only storage battery need to be put into wherein and open electric calorifie installation and heat, get final product the temperature in guard box body All the time it is in and is suitable to the scope that storage battery starts, though the coldest normal work that also can guarantee that storage battery of external environment condition, Meanwhile, why use carbon fiber electrothermal part, be owing to it has the heat that common metal electric heating element is difficult to reach Conversion efficiency, it is demonstrated experimentally that the hot-cast socket ability of carbon fiber pipe is common metal electric heating element hot-cast socket ability 4 times, thermal conversion efficiency is extremely strong, and energy saving, and cost is lower.

Additionally, carbon fiber electrothermal part to be embedded in caulking groove the combination completely that can make carbon fiber electrothermal part with casing Body, structure more consolidates compact, and on the one hand the setting of heat-conducting plate then can make carbon fiber electrothermal part institute caloric value more Scatter uniformly, promote faster so that the temperature inside the box can obtain within the shorter time, on the other hand, its Can also take precautions against acid liquid corrosion, safer after making storage battery placed on it, service life is longer.

Moreover, by the setting of control circuit plate, temperature sensor and heat abstractor is also made it have The more intelligent temperature control ability of freedom and flexibility, specifically, temperature sensor can temperature in monitoring box in real time Monitoring information is also passed to control circuit plate by degree, thus, and can be via circuit board to electric calorifie installation and heat radiation Device imposes Based Intelligent Control, and the present invention, preferably on the basis of 25 degree, starts temperature control in the range of positive and negative 5 degree Regulation, i.e. when the temperature inside the box fall the end to less than 20 degree time, electric calorifie installation can heat automatically, in the process, Electric controlled door is closed, radiator fan does not works, and when the temperature inside the box is more than 30 degree, electric controlled door can automatically open up, Radiator fan also can work automatically, and in the process, electric calorifie installation does not heats, so, and the temperature inside the box Effectively controlled between 20 degree to 30 degree, the most just can protect storage battery either in hot summer, Or can normally work all the time in cold winter, highly effective.
