The maximum wattage output of a 12V battery can range from 100 watts to 3000 watts, contingent on its capacity. A 12V battery rated at 100 amp-hours (Ah) can
On average, a typical 12V battery with a capacity of 100 amp-hours (Ah) can deliver 1 amp for 100 hours or 10 amps for 10 hours. This translates to 1,200 watt-hours (Wh) of total energy available for use, as power (in watts) equals volts times amps. Devices with lower power consumption can run longer on a 12V battery.
One key motor performance parameter to consider in a battery-powered application is efficiency. Maximizing motor efficiency helps minimize the required power capacity and hence the size and cost of the battery solution. For this reason, brushless DC (BLDC) motors are preferred over brushed DC motors but are typically higher in price.
So scientifically it is denoted as only Ah. For example, the Mahindra e20 has 10kWh energy stored in the battery. It can deliver approx. 208 Ampere current for one hour, at a rated voltage of 48V. How battery capacity affects range? A car's range depends on its battery's capacity and efficiency of use.
Generally, for a higher-power motor, a higher voltage is preferable. The selection of battery parameters is based on the range required for the vehicle and the capacity to provide peak discharge current and the duration for the peak current. Battery capacity (Ah or KWh) = (Mileage Requirement / Avg speed) x Avg current or power consumption.
Battery capacity is based on the desired operational run time of the equipment between recharging cycles and is simply the amount of charge a battery can hold. The standard measure for battery capacity is milliampere-hours (mAh) or amp-hours (Ah), which indicates how long the battery will last based on the current it outputs.
Battery capacity is effectuated by multiple factors like temperature and discharge rate. Battery performance drop considerably with temperature. Typical battery capacity range from 15 to 100Kwh.
