As a common gardening tool, Mower has been widely used in modern society. The power source of mower-the design and selection of lithium battery system are crucial to its performance and use experience. This paper will discuss the complete scheme of lithium battery system of lawn mower, including lithium battery selection, battery management system, charging technology and other aspects, providing reference for research and application in related fields.

1. Lithium battery selection:
   in the selection of lithium battery of lawn mower, factors such as battery capacity, voltage, cycle life and safety need to be considered. Common lithium battery types include lithium iron phosphate battery (LiFePO4), lithium manganese oxide battery (LiMn2O4), lithium cobalt oxide batteries (LiCoO2), etc. Different types of lithium batteries have their own characteristics, such as high safety and long cycle life of LiFePO4 batteries, which are suitable for long-term use scenarios such as lawn mower; LiCoO2 batteries have high energy density, it is suitable for scenarios with high capacity requirements. Therefore, when selecting lithium batteries, it is necessary to comprehensively consider various factors according to the actual needs of mower and select the most suitable battery type.

2. Battery Management system Design:
   the lithium battery management system of lawn mower is crucial to the service life and performance of the battery. A good battery management system can realize real-time monitoring of battery status, balanced charging and discharging, overcharge and overdischarge protection and other functions to ensure the safe and stable operation of the battery. In addition, the battery management system should also have remote monitoring, fault diagnosis and other functions, as well as data interaction with the mower control system to realize the overall management and control of the battery status.

3. Application of charging technology:
   the application of charging technology of mower is also an important link. The selection of charging technology should consider charging speed, charging efficiency and chargingFactors such as the adaptability of electrical equipment. Common charging technologies include ordinary socket charging, fast charging technology, solar charging, etc. When designing the lithium battery system of mower, the layout of charging equipment and the design of charging interface should be considered to ensure the safety and efficiency of the charging process and improve the working efficiency and reliability of mower.

The complete scheme of lithium battery system of lawn mower needs to comprehensively consider many aspects such as lithium battery selection, battery management system design and charging technology application. By reasonably selecting the type of lithium battery, designing excellent battery management system and applying convenient and efficient charging technology, the performance optimization, endurance improvement and operation stability improvement of mower can be realized. The comprehensive consideration and optimal design of these aspects will provide more reliable and efficient lithium battery system solutions for the use and maintenance of mower, and bring more convenience and benefits to the application scenarios of gardening tools.
