Electric sweeper battery insulation and heat dissipation

Date:2015-01-29

                                       

 

Batteries in the battery box, you need to consider the summer heat and winter heat preservation. Both requirements, according to the rational use of the battery condition and comprehensive factors to determine the local climate conditions.

Summer high temperature region, plus 10 ℃, as battery limit, is basically reasonable. High temperature damage to the battery is mainly diaphragm material aging degeneration. In the presence of commonly used temperature range, are not much change the properties of the cathode and electrolyte materials. Control the highest temperature rise not primarily by the method of forced cooling, but by reducing working current method, in the battery management system should have the battery temperature rise hints and warnings.

Electric sweeper with waterproof sealing requirement, radiation condition of the battery is poorer, the main measures of temperature control is to control the discharge rate of the battery. In different car use different batteries, the safety of charging and discharging rate is different, this need according to the practice of the accumulation of data, to determine the reasonable working point.

Winter heat preservation method can be used with thermal insulation layer. As long as after reaching the vehicle battery temperature above 0 ℃ can be recharged, charge last winter prefi lled with 0.1 C first small current. Stay after rises to 5 ℃ temperature, can be turned into large current charging with constant current.
