Notice that at 100% capacity, 12V lithium batteries can have 2 different voltages; depending if the battery is still charging (14.4V) or if it is resting or not-charging (13.6V). What is interesting to see is that a 12V lithium battery has an actual 12V voltage at only 9% capacity. Here is the. .
As you can see from this 24V lithium battery state of charge chart, the relative relationship between voltage and battery capacity is the same. .
You can see that 48V lithium battery voltage ranges quite a lot; from 57.6V at 100% charge to 40.9V charge. The 48V voltage is measured at 9% charge, the same as with 12V and 24V lithium batteries. Here is the. .
3.2V lithium batteries are those regular batteries you put in older TV remote controls. Here are the voltage discharges: As you can see, 3.2V LiFePO4 battery can output anywhere from 3.65V (at 100% charging) to 2.5V. The optimal charging voltage for a 24V lithium battery is generally around 29 volts. This voltage ensures effective charging without risking damage from overvoltage. [pdf]

The example models a battery pack connected to an auxiliary power load from a chiller, a cooler, or other EV accessories. The Controls subsystem defines how much current the charger can feed into the battery pack based on the measurements of the cell state of charge, temperatures, and. .
The battery cell is modeled using the equivalent circuit method. The equivalent circuit parameters used for each cell can be found in the. .
To use this module to create a unique battery module, first specify the number of series and parallel-connected cells. Then specify the cell type. .
In this example, a battery pack is created by connecting three battery modules in series. A resistance models the cable connection between individual modules. A DC current source models the charger current and it is connected to the battery pack using a cable modeled as a resistance. A power load across the battery terminals models the. .
To enable fast charging, a cold battery pack is heated up to allow the passage of larger currents. The DC current profile subsystem estimates the DC current as a function of the minimum cell temperature in the battery pack. The coolant inlet temperature is constant at 288.15 K and defined by setting FlwT to a constant input value of 15. [pdf]
