The energy stored in a battery is calculated by multiplying the voltage of the battery by the capacity of the battery in ampere-hours. For example, a battery with a capacity of 1000 mAh and a voltage of 3.7 volts would have an energy storage capacity of 3.7 watt-hours (Wh). It is important to note that battery capacity is not the same as the
Thermal capacitance is connected to the energy storage capacity and assumes no energy losses. It is defined as the heat flow necessary to change the temperature rate of a medium by one unit in one second: (5.124) C t h = q ( t) d θ ( t) d t = d Q ( t) d t d θ ( t) d t = d Q d θ. The SI unit for thermal capacitance is N-m-K −1 (or J-K −1 ).

A megawatt-hour (MWh) is the unit used to describe the amount of energy a battery can store. Take, for instance, a 240 MWh lithium-ion battery with a maximum capacity of 60 MW. Now imagine the battery is a lake storing water that can be released to create electricity. A 60 MW system with 4 hours of storage could work in a number of ways:
The battery capacity is expressed in units of milliampere-hours (mAh) or ampere-hours (Ah), and it represents the amount of energy that can be drawn from the battery over a specific period of time. For example, a battery with a capacity of 3,000 mAh can provide 3,000 milliamperes of current for one hour or 1,500 milliamperes for two
