1. Curve analysis
10AH lithium manganate battery 0.2C charging curve
Analysis:
1, the first stage of charging (0-30 min), the charging current is large, the charging is fast, and the battery internal resistance is small. Average charging speed v=0.025V/min
2. In the second stage of charging (30-250 min), the battery enters a stable state of charging and the internal resistance increases. Average charging rate v=6.82*10-4V/min
3, the third stage of charging (250-370 min), the charging amplitude is slightly faster than the second stage, and the internal resistance increases. V = 0.0025 v/min
4, during the charging process, the battery capacity is reduced.
5, battery capacitance C=△Q/△U=10*3600/1.2=30000F
2.10AH lithium iron phosphate battery 0.2C charging curve
Analysis:
1. In the first stage of charging (0-30 min), the battery internal resistance tends to increase, and the average charging rate v=0.01166V/min
2, the second stage of charging (30-260 min), the overall in a stable state of charging, internal resistance increases, v=4.3478*10-4V/min
3, the third stage of charging (260-310 min), the charging voltage rise is large, the internal resistance increases, v=0.01V/min
4, during the charging process, the battery capacity is reduced.
5, battery capacitance C=△Q/△U=10*3600/1=36000F
3. Comparative analysis of two batteries:
1, 10AH lithium iron phosphate battery than 10AH lithium manganese acid battery capacity is smaller.
2. In the first and second stages of charging, lithium manganese acid batteries are faster than lithium iron phosphate batteries, and the third stage is the opposite.
The internal resistance of both batteries tends to increase during the charging process, and the battery capacity decreases.
