Customer ServiceOnce the LiFePO4 battery is fully charged, a trickle charging current of 0.01C to 0.05C can be used to maintain the battery''s charge level. For the 100Ah LiFePO4 battery, the trickle charging current would be 1A (0.01C)
Customer ServiceIn the second case, the battery initial temperature is higher, so the control module can put more current into the battery pack. The temperature of the battery further rises due to the heat. This enables the control module to put more charging current into the battery pack. As a result, the battery pack net state of charge rises from 20% to
Customer ServiceIn charging mode, a charging circuit charges the battery pack; current flows into its HV+ terminal. In discharging mode, the battery pack provides power to an external load. For example, in EVs, the battery pack provides power to the electric motor, which converts the electrical energy to mechanical energy and propels the automobile.

The logic defined in the Controls subsystem determines the value of the current. A resistor models the HV cable and it is used to connect the charging port to the battery pack. The battery pack comprises three series-connected battery modules, with a total of 130 battery cells. The battery cell is modeled using the equivalent circuit method.
In this example the battery pack voltage is 12 volts which is exactly the same as each of the individual 12-volt batteries. 2) The capacity of the battery pack is the sum of the capacities of the individual batteries. Again, make sure that all of the batteries are the same size, that is that they have the same amp-hour capacity.
During the 1c current limit charge phase, the battery reaches 4.2V with only about 65% of charge capacity delivered, due to the voltage drop across the ESR. The charger must then reduce the charging current to prevent exceeding the 4.2V limit, which results in the decreasing current as shown in Figure 5.
About 65% of the total charge is delivered to the battery during the current limit phase of charging. Assuming a 1c charging current, it follows that this portion of the charge cycle will take a maximum time of about 40 minutes. The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V.
The battery pack net state of charge rises from 20% to about 42% during the 15 minutes of the charging process. In the second case, the battery initial temperature is higher, so the control module can put more current into the battery pack. The temperature of the battery further rises due to the heat.
