Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of accumulator cell heat preserving capacity increasing device is provided, make battery capacity in winter improve, and prolonged useful life, to reduce the use cost of electric motor car.
The technical scheme that technical solution problem of the present invention is adopted is:
Design feature of the present invention is the outside at storage battery, and the accumulator cell heat preserving sheath of temperature controllable at setting range is set.
The capacity of storage battery is to weigh storage battery can discharge what parameter of electric energy, it is except that outside the Pass having with the material structure of storage battery own, also much relations are arranged with ambient temperature, the accumulator cell charging and discharging capacity all descends with ambient temperature and reduces, the battery environment temperature of general manufacturer designing requirement is 25 ℃, under this temperature environment, if charge in batteries discharge capacity 100%, when surpassing 25 ℃, though the electric capacity of storage battery can surpass 100%, but the corrosion aggravation of Yin Gaowen bottom crown, 10 ℃ of storage batterys of every raising can be shortened half useful life, do not provide too high temperature environment so do not advocate in theory to storage battery.When temperature was lower than below 25 ℃, its relation was as shown in the table:
25 ℃ 20 ℃ 15 ℃ 10 ℃ 5 ℃ 0 ℃ of temperature
Capacity 100% 95% 90% 84% 76% 71%
When temperature is lower than after 0 ℃, charge/discharge capacity reduces more, and decline can reach 40%, and this is to cause electric motor car distance travelled in winter obviously to shorten so that be forced to the more immediate cause of new accumulator.Therefore have only as can be seen for storage battery provides ambient temperature near 25 ℃, the capacity of storage battery could be ideal, useful life could be the longest relatively.
Compared with the prior art, remarkable result of the present invention is embodied in:
When 1, in the winter time storage battery being charged, because ambient temperature is lower than 25 ℃, carry out heat compensation by the electric heater unit that utilizes the accumulator cell heat preserving sheath in the outside of storage battery, make the battery environment temperature be elevated to 25 ℃ rapidly, self institute's thermal discharge is kept this optimal charge temperature when utilizing charge in batteries more subsequently, can make battery capacity return to normal level.
2, during electric motor car travels in the winter time, storage battery discharges, because ambient temperature is lower than 25 ℃, electric heater unit by the accumulator cell heat preserving sheath carries out heat compensation in the storage battery outside equally, make the battery environment temperature be elevated to 25 ℃ rapidly, the heat that self is produced when utilizing battery discharging is more subsequently kept this optimal discharge temperature, can make storage battery have maximum discharge capacity, makes the electric motor car farther distance of travelling as warm season.
In a word, can not normally be used cold winter and the storage battery that can normally use warm season must not be changed by installing this device additional, just can recover normal the use, guarantee to survive the winter smoothly, and can also use the long period in the warm continuity in season of the next one, thereby prolong storage battery useful life greatly, improve the storage battery serviceability.

Embodiment
Referring to Fig. 1,, the accumulator cell heat preserving sheath of temperature controllable at setting range is set in the outside of storage battery 1.
Constituting of accumulator cell heat preserving sheath on the top layer of storage battery 1, but is provided with the temperature electric heating layer 2 of control automatically, and electric heating layer 2 is a working power with the power supply signal of the electrode tip 9 of storage battery 1, in the outside of electric heating layer 2, heat-insulation layer 3 is set.
In concrete the enforcement, as product, can external shell 7 be set in the appearance of heat-insulation layer 3, heat-insulation layer 3 can be selected material mould moldings such as polyethylene foamed, polyurethane foam, EPS, XPS, SAC for use; Electric heating layer 2 can adopt the electric blanket principle design to become heating net or utilize the electric iron principle design to become heating plate, controls automatically in order to realize temperature, answers relative set thermostat 8;
Shown in Figure 1, the inwall of heat-insulation layer 3 is designed to Turbogrid plates, air-flow connects between each grid 4, dual-side at the accumulator cell heat preserving sheath, the shutter 5 that can form gas channel in grid 4 is set respectively and goes out air door 6, wherein, shutter 5 with go out air door and be in the relative both sides of storage battery 1 in 6 minutes, and shutter 5 with go out the upper and lower, side that air door was in storage battery 1 in 6 minutes.The temperature on storage battery top layer was even when this version helped adopting heat preserving mode work in the winter time on the one hand, helped the ventilation and heat when working summer on the other hand.
Working method:
Winter, when storage battery is lower than 25 ℃ of chargings in ambient temperature, by external power source the temperature control electric heater unit is powered, electric heating layer 2 gets electric intensification, bring into play the heat insulation function of heat-insulation layer subsequently, the temperature automatically controlled function of spontaneous heat and temperature control electric heater unit can keep charging process to carry out in 25 ℃ constant temperature when utilizing charge in batteries, guarantees that with this charge in batteries can reach heap(ed) capacity.Ambient temperature when storage battery comes into operation is if be lower than 25 ℃, the temperature control electric heater unit is heated up by the power supply power supply of storage battery itself, it is same because heat-insulation layer has heat insulation function, the temperature automatically controlled function of spontaneous heat and temperature control electric heater unit keeps the battery discharging process to carry out in 25 ℃ constant temperature when utilizing battery discharging, make it have maximum discharge capacity, keep maximum distance travelled.
