Battery discharge time depending upon load
Battery capacity is a measure (typically in Amp-hr) of the charge stored by a battery. You may think that calculating how long a battery will last at a given rate of discharge is as simple as amp-hours: e.g. for a given capacity C and a discharge current I, the time will be, However, battery capacity decreases as the rate of discharge increases.

How does a DC/DC converter work on a lithium ion battery?
Now, high-voltage DC power from the lithium ion battery needs to be converted into low-voltage DC power with which the lead battery is charged, and the DC/DC converter makes this conversion. Low-voltage DC power resulting from the conversion allows various components in the EV to operate with proper voltage supplies.
Why does a battery have a depth of discharge?
This occurs since, particularly for lead acid batteries, extracting the full battery capacity from the battery dramatically reduced battery lifetime. The depth of discharge (DOD) is the fraction of battery capacity that can be used from the battery and will be specified by the manufacturer.
How long can a battery be discharged?
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
What is the difference between a DC/DC converter and a battery?
In the measurements, the battery is discharged at constant current, resistance or power, while the DC/DC converter generates fixed output voltages, unless it is out of regulation. Figure 3, Figure 4 and Figure 5 show the measured battery life achieved with the three devices used to generate voltages from 3 V to 4 V.
How does a power conversion system work?
The PCS charges the batteries in the event of excessive power generation. The PCS provides the power with the stored energy if the grid need extra energy. AC/DC bidirectional converters, control elements, switching components, and cooling compose a power conversion system. There are many layers of remote control for the system.
What is a controlled power discharge circuit?
Controlled-power discharge circuit. The inset shows the basic feedback principle. One reason for using a voltage regulator is to maintain a constant voltage across the load at a level substantially less than a fresh, fully charged battery's terminal voltage, in order to minimize power dissipation in the load.
