2. General characteristics
2.1 Discharge
2.1.1 discharge termination voltage:
To ensure the safety and maximum battery life, battery discharge termination voltage and the size of the battery discharge current, discharge current, battery voltage can be lower end, whereas the discharge current, battery termination voltage is higher. (Table 1) at different power rates recommended discharge termination voltage.
Discharge current discharge termination voltage: (VPC)
Less than 0.1CA 1.75
0.11-0.17CA 1.70
0.18-0.25CA 1.67
0.26-1CA 1.60
Than 1.1CA 1.30
2.1.2 Discharge capacity:
Battery discharge and the discharge capacity of the main current and ambient temperature
Battery capacity and discharge current relationship:
(Figure 1,2,3) for the FP, LFP, CFP model battery discharge rates at different conditions, the capacity of the release, can be seen from the figure, the greater the discharge rate, the smaller the capacity of the battery can discharge.
2.1.3 Battery Capacity and Environmental Temperature:
In the discharge current constant, high temperature, the battery discharge capacity and more, on the contrary, the ambient temperature is low, the battery discharge capacity less (figure IV) relationship for the battery capacity and temperature curves.
2.2 Charging
2.2.1 Charge Method
Charging method, It is important for the battery, incorrect battery charging method will charge or charge less, affect battery performance and life.
Common charge following two methods.
A, constant current limiting charge
B, constant current charging
Constant charge current limit:
Of VRLA batteries, the VRLA battery charging method is the best charging method. Control the charging voltage and ambient temperature and battery the way.
Spare battery: 2.23 ~ 2.30 / single cell, at 25 ℃,
Cycle with battery: 2.40 ~ 2.50 / single cell, at 25 ℃.
Note: Maximum charging current is generally set at the beginning not more than 0.3CA,
Figure 5-6 for the battery charging curve, can be seen from the figure, at 25 ℃ when the battery charge voltage of 2.30V / single cell, the battery is fully charged, the charge current reduced to 0.5 ~ 4mA/AH, remain change.
When the battery is 2.4V / single cell, the battery is fully charged, the charge current reduced to 3 ~ 10MA/AH, remain unchanged.
Constant current charge:
The method used to charge the battery, note the battery is fully charged rechargeable power supply must be immediately cut off, otherwise it will overcharge the battery, and damage to the battery performance and life, using constant current charging, the charging current is generally not more than 0.1CA, when the charge The last time the battery discharges electricity to the amount of 1.07 ~ 1.15 times that of the battery is fully charged.
2.2.2 Temperature effects on the battery charge voltage:
Because of chemical reactions accelerated by increasing temperature, the decrease of temperature slows down.
In order to prevent over charge or under charge the battery when the battery temperature is not 15 ℃ ~ 35 ℃, the need to adjust the battery charging voltage.
Adjustment method is:
At 25 ℃ as the reference, voltage adjustment coefficient: ± 3MV / ℃ single-cell l (battery backup); ± 4MV / ℃ single-cell l (cycle battery),
For example: use of a UPS battery backup 8 12V65AH to do in summer when the battery room temperature is 40 ℃, the charging voltage from 8 × 6 × 2.30 = 110.40 should be reduced to:
8 * 6 * [2.30-3 (40-25) / 1000] = 108.24V
Room temperature in winter when the battery dropped to 10 ℃, the charge voltage should be increased to 110.40V:
8 * 6 * [2.30 +3 (25-10) / 1000] = 112.56V (Figure VII) to charge the battery voltage and temperature relationship curve.
2.2.3 Charging time:
In terms of battery backup when the battery-powered, the battery needs recharging time, generally not less than 24H. In terms of recycling used batteries, if you know the last time the initial discharge capacity and charge current can be calculated by the following formula is 25 ℃ ambient temperature required charging time.
A, when the discharge current is greater than 0.25CA when
Tch = Cdis / I + 3 ~ 5
B, when the discharge current is less than 0.25CA when
Tch = Cdis / I + 6 ~ 10
Note: Tch battery charging time required for full power (H)
Cdis a discharge on the battery power (AH)
Maximum initial charging current I (A)
