Low-temperature-resistant lithium battery with protection box for street lamp

Abstract

The low-temperature-resistant lithium battery comprises a stand column and a battery mounting frame, the top of the stand column is fixedly connected with a lamp post, a mounting groove is formed in the surface of the stand column, the battery mounting frame is located in an inner cavity of the mounting groove, and a battery pack is arranged in an inner cavity of the battery mounting frame; by arranging the battery pack, the electrothermal film, the heat preservation layer, the temperature sensor and the temperature controller, the low-temperature-resistant lithium battery used for the street lamp and provided with the protection box is jointly constructed, and when the temperature controller monitors that the temperature of the battery pack is lower than the preset starting temperature through the temperature sensor, a power source of the electrothermal film is switched on; when the temperature of the battery pack reaches the closing temperature, the temperature sensor cuts off the power supply of the electric heating film, the operation is cycled, and the heat preservation layer is arranged, so that the diffusion of the temperature can be blocked, and the consumption of heat energy can be reduced.

Description

technical field [0001] The invention relates to the technical field of street lights, in particular to a low temperature resistant lithium battery for street lights with a protective box. Background technique [0002] Lithium battery solar street lights, which do not emit CO2 and SO2, and have no noise, solid waste and other pollution of conventional power generation, are currently one of the most important renewable energy technologies. With the continuous development of lithium battery solar street light power generation technology, lithium batteries The application of energy saving, environmental protection, safety and other advantages has become the new darling of the urban road lighting industry, and the market potential is huge. In different regions, such as cities or villages, the requirements for the lighting density of lithium battery solar street lights are different, but charging through lithium battery solar street lights According to the working principle of dis...
