A kind of thermostatic energy-storing lithium battery used suitable for cold district
Technical field
Lithium battery body field is the utility model is related to, is specially a kind of thermostatic energy-storing lithium used suitable for cold district
Battery.
Background technology
Solar street light is powered using crystal silicon solar energy battery, to replace a kind of new of conventional utility power illumination
Lamp post structure, cable need not be laid with, not produce the electricity charge, installation easy maintenance, security performance height, energy conservation and environmental protection, economy in fact by having
With the advantages that, therefore, apply more and more widely the primary and secondary arterial highway of Urban Streets, residence district, manufacturing enterprise, tourism scape
The various places such as point, parking lot.
The energy-storage battery traditional approach of solar street light is equipped with lead-acid accumulator, due to lead-acid accumulator weight very
Greatly, it is impossible to hung on lamp stand, therefore, underground can only be embedded in.And embedded underground, not only construct cumbersome, but also stolen situation is more
Hair, can not ensure the normal use of street lamp.The lead-acid accumulator that street lamp is equipped with gradually is changed to lithium battery body at present.Lithium electricity
Pond body has the advantages that capacity is big, small, light-weight, environmentally friendly, long lifespan, accordingly it is also possible to be hung on lamp stand, due to
Recyclability is poor, therefore, the less generation of situation of loss.But at low ambient conditions, the performance meeting of lithium battery body
It is deteriorated.And solar street light is set up under the external environment condition of block etc., the cold district of north of china in winter, environment temperature are particularly
Degree it is below freezing be a kind of normality situation, under this environmental condition, can not just ensure lithium battery body solar street light
Normal illumination uses.
