How to choose lithium batteries for AGV small cars?

With the widespread use of AGV cars in the transportation industry, AGV cars also have certain requirements for the selection of power sources. Generally, AGV cars use lithium batteries. So how to choose a suitable AGV small car lithium battery, we need to consider these aspects.

1. Functional requirements
It is necessary to ensure that the AGV car operates without any faults and continuously, with lithium batteries being the most important part. The AGV small car lithium battery should have a safe and reliable BMS management system, which can cooperate with the AGV small car to complete the work. At the same time, it should also have the lithium battery capacity, voltage, current, and high/low battery alarm function.

2. Charging efficiency
AGV cars generally operate continuously 24 hours a day, and the charging method is also automatic. The charging time is usually when the AGV car is not working or parked for a short period of time, and the charging frequency will be multiple times a day, with each charging time being very short. This requires high charging capacity of the battery, ensuring that the charging capacity of the battery meets the discharge capacity.

3. Safety performance

Lithium batteries have low safety performance due to unstable internal chemical reactions, and AGV cars use high current charging methods, which requires ensuring safety during charging. At present, the most common choice for AGV small car lithium batteries is ternary lithium batteries, which have high energy density, large energy storage, but relatively low safety performance. If the safety performance of lithium batteries is the highest, it should be lithium iron phosphate batteries.
