Detailed description of the invention
A kind of anti-low-temperature protection device of lithium battery solar street lamp; see Fig. 1; comprise lithium battery group 1 and encapsulating housing 2; lithium battery group is encapsulated in housing; described lithium battery group receives the charging of solar panels and provides power supply to street lamp; wherein; the surface of described lithium battery group is pasted with temperature control module 3; a heat-insulation layer 4 covers lithium battery group and temperature control module; a lithium battery protection board 5 is arranged in housing; the safe discharge and recharge of control circui lithium battery on baffle, realizes described solar panels or lithium battery group provides power supply to temperature control module.
In embodiment: described heat-insulation layer is polyurethane material heat-insulation layer, and thickness is 10mm to 150mm according to different areas, usually at 20 to 50mm.
In embodiment: the temperature-control circuit that described temperature control module comprises heater element and is connected with heater element, first heater element is attached on a conducting strip, and conducting strip is attached to a side surface of described lithium battery group or multiple side surface; Conducting strip is wherein the material that heat conductivility is good, such as: Copper Foil or aluminium foil.
Wherein, described heater element is PTC heating element heater, PTC heating element heater is the heating element heater part utilizing heated at constant temperature PTC thermistor constant temp. warming characteristics design, in middle low power heating occasion, PTC heating element heater has the incomparable advantage of the conventional heating element such as constant temp. warming, the flames of anger, thermal conversion rate are high, minimum by power supply voltage influence, natural life-span is long.Heated at constant temperature PTC thermistor has constant temp. warming characteristic, its principle be PTC thermistor power up rear self-heating heat up make resistance enter transition district, heated at constant temperature PTC thermistor surface temperature will keep steady state value, this temperature is only relevant with applied voltage with the Curie temperature of PTC thermistor, and substantially irrelevant with environment temperature.Use PTC heating element heater, power to PTC even if control circuit is uninterrupted because of out of control, PTC also can only be increased to its ceiling temperature (being generally not higher than 60 degree), thus prevents the damage to lithium battery and unexpected generation.
For this reason, temperature-control circuit described in the present embodiment comprises a temperature sensor and ON-OFF control circuit, temperature sensor is attached to lithium battery group surface, and the signal of temperature sensor is connected to ON-OFF control circuit, and ON-OFF control circuit controls circuit ON and the shutoff of heater element.
