Lithium battery low-temperature charging system and charging method thereof

Abstract

Disclosed is a lithium battery low-temperature charging system. The system comprises a lithium battery pack, a heating heat-preserving sleeve, a charging power supply, a single-chip computer, and a temperature sensor; the lithium battery pack and the heating heat-preserving sleeve are connected with the charging power supply, the charging power supply is connected with the single-chip computer, and the single-chip computer is connected with the temperature sensor. The system has the advantages that under a low-temperature condition, a lithium battery in the heating heat-preserving sleeve is firstly heated by the charging power supply, the heating heat-preserving sleeve has functions of temperature automatic controlling and heat preserving by heat insulation, the temperature sensor only detects temperature of the battery, when the temperature of the lithium battery reaches a normal charging temperature, the lithium battery is charged again by the charging power supply, an effect of normal charging of the lithium battery under the low-temperature condition is achieved, normal charging of the lithium battery is ensured, and the problem that the lithium battery is difficult to charge under the low-temperature condition is solved to facilitate use of people. The charging system has the advantages of being good in using effect and applicable to be popularized.

Description

technical field [0001] The invention relates to the technical field of novel batteries, in particular to a lithium battery low-temperature charging system and a charging method thereof. Background technique [0002] At present, shared bicycles have become an important means of transportation in urban life. With the widespread application of shared bicycle smart locks, lithium batteries are more widely used in shared bicycles. The lithium battery in the smart lock is mostly charged by solar panels or hub power generation, and the charging voltage is around 6-7V. However, in the cold regions of the north, or in unusually cold seasons, due to the low temperature, the lithium battery cannot be charged normally, and the smart lock faces the risk of being unable to activate. Therefore, there is an urgent need in the market for a system that can quickly heat the lithium battery of a bicycle smart lock under low temperature conditions to ensure the normal charging of the battery. ...
