Abstract
The invention relates to a low-temperature heat-preservation control device, which is developed aiming at overcoming the defects of the lithium battery pack that the discharging performance is worsen at a low temperature (less than -10 DEG C). The device consists of a lithium battery pack with a shell and an external heat-preservation material. The lithium battery pack with the shell is composed of a lithium battery pack, a heating device, a multi-station shifting battery control switch, a shell, an internal connecting conducting wire and a cable. The external heat-preservation material consists of vacuum cotton fiber materials. The lithium battery pack can supply the power normally at the normal temperature and the high temperature, a control switch of a battery box panel is shifted to a heating position when the ambient temperature is -10 DEG C or less than -10 DEG C, the lithium battery pack is discharged through the internal heating device load, the increasing of the temperature inside the battery box is facilitated, the low-temperature discharging property of the lithium battery pack is improved under the heat preservation of the external heat-preservation material, and the low-temperature application requirement of an electronic product can be met.
Description
The technical characterictic of invention: under low temperature, the lithium battery group, by battery case body internal heat generation device load discharge, raises temperature in battery and battery case, improves lithium battery group cryogenic discharging characteristic.Protection range: lithium battery group low temperature heating apparatus, outer insulation enclosed material.
Technical field: the present invention relates to a kind of lithium battery group low temperature attemperator, can effectively improve the poor problem of lithium battery group cryogenic discharging characteristic, make the lithium battery group can meet the requirement of electronic product low-temperature working.
Background technology: at present, lithium battery is large with the battery specific capacity, little, the lightweight advantage of volume is widely used in various electronic products, but lithium battery low temperature (10 ℃ and following) discharge performance variation, discharge capacity is little, even can not, with the 0.2C multiplying power discharging, often can not use at some low temperature environments.
Summary of the invention: in order to overcome the shortcoming of lithium battery low temperature (10 ℃ and following) discharge performance variation, the technical solution used in the present invention is: when low temperature is used, control switch on the lithium battery assembly housing is allocated to " heating " position, the lithium battery group is by discharging to inner attemperator, the battery case internal temperature is raise, the insulation of lithium battery group overcoat insulation material, lithium battery group low-temperature characteristics is improved, by choose reasonable lithium battery pool-size, can make the lithium battery group meet the instructions for use of electronic product low temperature.
Accompanying drawing explanation: Fig. 1: lithium battery group low temperature attemperator electrical schematic diagram.
Fig. 2: lithium battery group low temperature attemperator winding diagram.
Embodiment: lithium battery group low temperature attemperator annexation is: the anodal main contacts that connects toggle switch of lithium battery group.Control switch connects respectively battery case internal heat generation device terminals 1, service cable "+" end (normal operating conditions), and lithium battery group negative pole is connected to battery case internal heat generation device terminals 2, service cable "-" end.Assembly relation is: electro-heat equipment is wrapped in outside the lithium battery group, by after toggle switch exact connect ion on lithium battery group and housing face-plate, pack in lithium battery casing, again the sealings such as lithium battery assembly housing, panel are assembled, connect battery and stube cable and draw from the heat insulating material for external breach, fixedly the heat insulating material for external bag.
The invention has the beneficial effects as follows: in low temperature (10 ℃ and following) situation, the lithium battery group by electro-heat equipment load discharge, ambient temperature in lithium battery group housing is heated, with heat insulating material for external, be incubated, thereby improve lithium battery group low-temperature characteristics, make it to meet the instructions for use of electronic product low temperature.
Claims (2)
1. lithium battery group low temperature temperature preservation control device, can be used for improving lithium battery group low temperature (below 10 ℃) discharge performance, it is characterized in that: during low temperature (below 10 ℃), by the battery case panel control switch, start the lithium battery group by internal insulation device load self discharge, the lithium battery low temperature active is improved and the interior ambient temperature rising of lithium battery group shell.
2. a kind of lithium battery group low temperature temperature preservation control device according to claim 1, by the outside sealed thermal insulating material insulation of lithium battery case, thereby improve lithium battery group cryogenic discharging characteristic, and the instructions for use of electronic product while meeting low temperature.
