Lithium battery are widely used in theapplications field, especially in the electric bicyclesfield. Subsequently, many countries have stepped up effortsto support the research.For a variety of battery explosion of electronic products happened, people pay great attention to the safety of lithium battery charging.In view of the demand for charging products, firstly, this article has carried out the related research. This paper introduces the background, purpose and significance of the researchthen analyzes the current research status of the lithium-ion battery charger. This paper introduces the important components of the charger. The functiondiscussed is need to achieve. It provides the basis choices of charging scheme and charging method.Secondly, the paper describes the various modules of the hardware design. The design of charging circuit, alarm circuit, voltage detection circuit, temperature detection circuit and MCU circuit are discussed respectively. At the same time it introduces a detailed picture about the communication. The paper introduces the software design of the whole charger design. Including the programming of the MCU and the Qt software program design.Fi
