What are the techniques for selecting batteries for the earth robot?

The battery capacity is of course the first concern, because it is directly related to the working hours of the sweeping robot. Of course, the capacity should be large. However, the bigger the better, because to increase the battery capacity, the volume of the battery will also increase at the same time, increasing the thickness and weight of the sweeper, taking into account the battery life and the overall performance of the machine, the sweeping robot's lithium-ion battery capacity is more than Between 2000~3500mAH. In addition to paying attention to battery capacity, you must also choose the type of battery. Different types of batteries have different charge and discharge times, stability, lifespan, and safety. And most of the sweepers are in a charging state when they are not working. The safety and stability of the battery must be considered. If overcharging occurs, it is likely to cause accidents such as fire. At present, the commonly used batteries for sweeping robots are: 1. Advantages of polymer lithium-ion batteries: small size, lighter weight, no memory effect, charging as you use it, and low self-discharge rate. Disadvantages: The safety and stability are not as good as Ni-MH batteries, and they are expensive. 2. Advantages of Ni-MH battery: high safety, good stability and low price. Disadvantages: large size, heavier, memory effect, unable to charge quickly, high self-discharge rate 3. Advantages of lithium iron phosphate power battery: light weight, no memory effect, charge as you use it, low self-discharge rate, large capacity , High humidity resistance, high current fast discharge, long life and environmental protection. Disadvantages: The tap density of the lithium iron phosphate cathode material is small, and the volume of the lithium iron phosphate battery of equal capacity is larger than that of the lithium ion battery, so it has no advantages in the miniature battery. At present, the safety of lithium-ion battery technology has developed more maturely. I personally think that it is more reliable to choose a product with a mature technology. In terms of capacity, the larger the choice within the achievable range of industry technology, the better.
