Degree, reason is exactly temperature battery performance is influenced it is bigger, internal resistance, charging performance, discharge performance, safety including battery,
Service life etc..
Influence of the temperature to discharge performance is reacted directly into discharge capacity and discharge voltage.Temperature reduces, the internal resistance of cell
It increases, electrochemical reaction rates slow down, and polarization resistance increases sharply, and discharge capacity of the cell and discharge platform decline influence battery
The output of power and energy.Influence of the temperature to overpotential is more significant, and temperature is higher, and overpotential is smaller, and electrode reaction is more held
Easily carry out.This is because electrode discharge reaction overpotential is determined by two factors: the 1. charge on alloy and electrolyte contacts face
Shift resistance；2. diffusional resistance of the hydrogen atom from alloy bulk to surface.Temperature raising makes hydrogen atom diffusion and electric charge transfer speed
Degree is accelerated, and promotes the progress of electrode reaction, reaction overpotential reduces, thus the discharge capacity of battery increases, equally, in high tender feeling
Under condition, the discharge power ability of battery can also be risen.Under low temperature condition, the ohmic internal resistance of battery also increases, and influences battery
The output of discharge power.For lithium ion battery, same cryogenic conditions discharge capacity sharply declines, especially -20 DEG C of item
Under part, the performance of battery has more significant reduction.
On present society, there are the work of many low temp operations, such as plateau and mountains work, south poles scientific investigation work, modern times
Field test operation under the low temperature workshop in chemical plant and cold climate etc., many work require the branch of laptop
Such issues that hold, solve in the market generally passes through external power supply or assists the side of low temperature resistant battery by increasing inside notebook
Formula, but external power supply is only applicable to indoor use, and most of low temp operation is outdoor work；Increase low temperature resistant boosting battery
On the one hand battery cost is increased, on the other hand because the product that notebook itself is a highly integrated, inner space utilization rate is
Through high, and a part of space will necessarily be sacrificed by increasing boosting battery, thus influence the space structure of entire laptop
Design.
Summary of the invention

The technical scheme of the invention to solve the technical problem is:
A kind of laptop suitable for low temperature environment, the laptop back side are equipped with battery compartment；The battery
Storehouse includes thermostat galvanothermy component；The thermostat galvanothermy component is powered by the battery of the laptop.
The thermostat galvanothermy component includes the heater circuit, electric heating film and temperature conditioning unit triggered in temperature sensor；Institute
It states electric heating film and the battery compartment bottom is bonded in by high-temperature-resistant adhesive fixation；The temperature conditioning unit includes by default temperature
The actual temperature that temperature sensor described in threshold comparison measures is spent to control the temperature controlling chip and relay of the electric heating film switch
Device.
Preferably, the high-temperature-resistant adhesive is thermostable phenolic resin glue, high temperature resistant epoxy, fire resistant polyimide
One of glue and electrodeless silicate high-temp glue.
Preferably, the electric heating film is graphene electric heating film.
Preferably, the graphene electric heating film includes graphene heating film；Upper and lower two faces of graphene heating film
Teflon insulation film has been adhered by organosilicon joint sealant respectively.
The utility model has the advantages that
The present invention in the battery compartment of laptop by being fixedly installed ultra-thin graphene heating film, by notebook electricity
The built-in battery of brain itself is powered, and the intelligent control heater circuit based on temperature sensor rationally controls the interior of battery compartment
Portion's temperature guarantees the laptop normally continuation of the journey operation at low ambient temperatures.Graphene heating film skill set by the invention
Art is mature, safe, and superthin structure does not account for battery compartment space, and temperature raising significant effect is low in cost, implements simply, to be suitble to a wide range of
It promotes.
