The fundamental approach involves understanding the nominal voltage and capacity of the battery. The formula for lead-acid battery kWh is: markdown kWh = Voltage x Capacity (in Ah) It’s crucial to consider the efficiency factor when calculating to enhance accuracy.
For lead acid batteries the rated capacity (i.e. the number of AH stamped on the side of the battery) is typically given for a 20 hour discharge rate. If you are discharging at a slow rate you will get the rated number of amp-hours out of them. However, at high discharge rates the capacity falls steeply.
Lithium-ion batteries, prevalent in electric vehicles and portable electronics, have a different approach to kWh calculation. The formula takes into account the nominal voltage and ampere-hours (Ah): markdown kWh = Voltage x Capacity (in Ah) Understanding these variations ensures precise calculations tailored to specific battery types.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
Lead–acid batteries were used to supply the filament (heater) voltage, with 2 V common in early vacuum tube (valve) radio receivers. Portable batteries for miners' cap headlamps typically have two or three cells. Lead–acid batteries designed for starting automotive engines are not designed for deep discharge.
Ampere hour (Ah) is a unit of measurement used to describe the capacity of a battery. It is calculated by multiplying the current (in amperes) flowing through a circuit by the time (in hours) for which the current flows. The resulting value is the amount of electric charge that has passed through the circuit.
Example: Battery Ah x Battery Voltage ÷ Applied load. So, for a 110Ah battery with a load that draws 20A you have: # 110÷20 =5.5 hours. The charge time depends on the battery chemistry and the charge current.
