Abstract
The invention relates to electronic and new energy industries. The invention relates to a low-temperature protection package for a lithium battery. During lithium battery packaging, the lithium battery is externally wrapped with a heat conducting layer, a constant temperature heating plate is clung to the heat conducting layer, and the constant temperature heating plate is externally wrapped with a thermal insulation layer. The power supply of the constant temperature heating plate comes from the output end of a lithium battery guard plate. The package can ensure that the lithium battery works at a temperature higher than a set temperature, and the problem of using the lithium battery in a low-temperature environment can be solved.
Description
Technical field
The present invention relates to electronics and new forms of energy industry, be mainly used in lithium battery energy storage battery field.
Technical background
Lithium battery technology development in recent years, range of application is more and more wider, however lithium battery is higher to application environmental requirement, and particularly low temperature is very large to the performance impact of lithium battery.Although adapt to the lithium battery of low temperature, also releasing, but still can not meet the requirement of lower temperature, this just objectively needs to find a kind of, and assurance lithium battery is worked in uniform temperature environmental field.
For solving the lithium battery problem high to temperature requirement, there is human hair to understand insulating box, can heat, can freeze again, can guarantee the temperature of the operational environment of lithium battery.But insulating box cost of manufacture is higher, range of application has certain limitation, particularly in product application cheaply, does not more possess advantage.
Lithium electricity type solar street light started to rise over the past two years, and range of temperature is large out of doors, and particularly the use in winter lithium battery at China's North of Huai River has run into problem.For addressing this problem, the present invention proposes a kind of new lithium battery packing, simply can solve the object of protecting lithium battery under low temperature environment again.
Summary of the invention
First the present invention will make a constant temp. warming plate, and its effect is to produce steady temperature.As shown in Figure 2, Rt is thermistor to its structure, if keep the temperature of battery, is T, and the resistance of R2, R3, R4 is chosen as the resistance of Rt at T temperature.If temperature is lower than T value, the resistance of Rt will raise, and the output of comparator is high level, switching tube Q1 conducting, heater element heating.After the heating through after a while, temperature rises, and Rt resistance raises, after higher than temperature T value, the resistance of Rt lower than R2 after, through comparative voltage, comparator is output as low level, heating is turned off.And so forth, the temperature that maintains battery is not less than the object of T value.
In the present invention, the energy source of constant temp. warming plate is in battery or the external power source that charges the battery.The power input line of heating board is connected on the output stage of lithium battery protection board, and when lithium battery can outwards be powered, its energy source is in battery, and when battery can not supplying power for outside, its energy is from external charge power supply, as the photovoltaic panel in solar street light.
Heat-conducting plate is also one of them part, and the heat that constant temp. warming plate sends reaches battery around through heat-conducting plate, so that homogeneous heating battery.Heat-conducting plate wraps in battery around, and constant temp. warming plate is close on heat-conducting plate.
Heat-insulation layer is the skin of packing, requires to have the material of good thermal insulation property.Heat insulation effect is better, and the energy that constant temp. warming plate consumes is fewer, and therefore, the selection of outer heat-insulation layer and packing technique are also important rings wherein.

Embodiment
A kind of low-temperature protection packing of lithium battery, it forms structure: lithium battery is surrounded by heat-conducting plate outward, is close to constant temp. warming plate on heat-conducting plate, and outermost layer is heat-insulation layer, and low-temperature protection is restriction low temperature, and when temperature is lower than a certain limiting temperature, constant temp. warming plate just heats.
The power supply of described constant temp. warming plate is connected on the output of lithium battery protection board, and when battery can supplying power for outside, its energy source is in lithium battery, and when battery can not supplying power for outside, if extraneous power supply charges to battery, energy will derive from external charge power supply.
When the area of described constant temp. warming plate is larger, can save heat-conducting plate, because its effect of larger heating area is equivalent to heater, be attached on heat-conducting plate.Constant temp. warming plate area greatly to a certain extent after, the skin that is characterized as lithium battery of packing is heating board, outermost layer is heat-insulation layer.
Described constant temp. warming plate is comprised of thermistor, comparator, switch element and heating element.
Described heat-insulation layer must have the material of good thermal insulation property.
