Lithium battery capacity calculation Calculating the capacity of a lithium battery involves understanding a few basic principles. The capacity is typically calculated using the formula: Capacity (Ah)= Energy (Wh)/Voltage (V) Imagine you have a battery with an energy rating of 36 watt-hours (Wh) and a voltage of 12 volts (V).
Here’s a quick glossary of the key lithium-ion (li-ion) performance metrics and why they matter. 1. Watt-hours Watt-hours measure how much energy (watts) a battery will deliver in an hour, and it’s the standard of measurement for a battery.
Understanding the capacity of a lithium battery is vital for several reasons: Estimating Battery Life: Knowing the capacity helps you predict how long the battery will last on a single charge. This is crucial for planning usage, especially for devices you rely on heavily.
There are several ways to get Lithium-Ion State of Charge (SoC) measurement or Depth of Discharge (DoD) for a lithium battery. Some methods are quite complicated to implement and require complex equipment (impedance spectroscopy or hydrometer gauge for lead acid batteries).
Charge rate or charge speed Charge rate or speed is how long it takes a lithium-ion battery to be recharged after use. This is often measured in time and capacity range (i.e. 20 min to charge from 10-80% capacity) or measured in C-rate, same as discharge (i.e. a 6C capable battery would charge in roughly 10 minutes).
Battery capacity estimation is one of the key functions in the BMS, and battery capacity indicates the maximum storage capability of a battery which is essential for the battery State-of-Charge (SOC) estimation and lifespan management.
