Problems solved by technology
The operation of bicycles is greatly affected by seasonal changes and weather conditions. No matter what the weather is, no matter when and where, the battery of the shared bicycle must provide the energy supply for the positioning of the bicycle and the communication of the headquarters, so the lithium-ion battery of the shared bicycle requires more High, but most of the current lithium batteries still use manual charging, and the lithium batteries of shared bicycles are difficult to maintain. If all shared bicycles are manually charged, it will cause a lot of waste of manpower and material resources, and it is a waste of power resources, making it difficult to maintain the safety of lithium batteries sex and reliability

The invention relates to the technical field of battery charging, in particular to a solar charging circuit of a lithium battery. The solar charging circuit includes a step-down charging module used for reducing the output voltage of a solar panel to a lithium battery charging voltage, a sampling module used for monitoring the output voltage and the output current of the solar charging circuit and the temperature of the lithium battery, a DSP controller used for collecting a sampling signal sent by the sampling module and sending a control signal and further used for controlling on-off of the step-down charging module, and a protection module used for collecting the control signal sent by the DSP controller. A secondary protection circuit for protecting the lithium battery is arranged between the step-down charging module and the lithium battery. A lithium battery solar charging function is achieved. The solar charging circuit has high safety and long service life, needs no manual charging, and is energy-saving and environment-friendly.
Description
technical field [0001] The invention relates to the technical field of battery charging, in particular to a solar charging circuit for a lithium battery. Background technique [0002] Shared bicycles provide bicycle and bicycle sharing services, which is a new normal of the sharing economy. A GPS positioning system and a communication module to communicate with the headquarters must be installed on the shared bicycle. The operation of bicycles is greatly affected by seasonal changes and weather conditions. No matter what the weather is, no matter when and where, the battery of the shared bicycle must provide the energy supply for the positioning of the bicycle and the communication of the headquarters, so the lithium-ion battery of the shared bicycle requires more High, but most of the current lithium batteries still use manual charging, and the lithium batteries of shared bicycles are difficult to maintain. If all shared bicycles are manually charged, it will cause a lot o...
