It may be used to calculate the run duration of devices that demand a certain amount of watts or amps. For NiFe, for example, using Solar this could typically be <65% of the Ah rating for 4~6 hours. We have a whole web page tutorial explaining the method and theory of calculating how much battery capacity you need. These are typically multiples of 12 volts. Answer (1 of 2): To calculate the charging time of a smartphone you should have proper information about the output of the charger and about the battery capacity of a phone. The equivalent of 10000 mah is around 3.7 watt-hours or 3.7 amp-hours. . The same battery discharged at 0.5C provides 500mA for two hours. In our case, = 90/1.6. We use a simple formula: Nbr Panel * Watt per Panel / Battery Voltage. The Electric Vehicle Calculator, however, takes into account the 10% loss, and the individual . Based on this, we can now calculate how long will a 200 Ah battery be able to power an 800 W 240 V air conditioner: 200 Ah Battery Life = 200 Ah / 3.33 A = 60 hours. Here is how the Battery charging time calculation can be explained with given input values -> 200 = 3600000/5. You can convert Watt-hours to Amp-hours by dividing by the . For information on how this calculator works see How to calculate the Watt Hours (Wh) of a lithium battery. The amp-hour how much charge is stored in a battery multiplied by the average battery voltage will provide an estimate of how many watt-hours a battery contains. Typical Voltage in Electric Bike batteries is 36v, 48v, 52v, and 72v.

Battery charge time = (Battery capacity Wh/Solar panel Watt) + 30%.

mAh means milli-Ampere per hour. That's because an 800 W air conditioner on 240V requires fewer amps than an air conditioner on 120V. 3) Once you have calculated the solar panel as per the above calculations, it's time to calculate the AH rating for the batteries that might be required for operating the specified load under all conditions. Calculate duration that milliamp hours lasts. For example, a battery rated at 1000mAh provides 1000mA for one hour if discharged at 1C rate. You can choose two modes: - The Easy Mode: This is if you want a fast response without filling in all details of your panel's array. Videos you watch may be added to the TV's watch history and influence TV recommendations. Your output will be displayed. Select a 2nd battery pack cell count if you want to check your wiring of two different packs. So, in this example, it'd take about 9 hours to charge a 48 volt battery with a 960 watt solar panel. 2.

So if a 5 Volt battery has 20 Watt Hour rating, and, it draws 2 Amp current, then the Watt delivered by Battery = 10 Watts ( 5 Volts x 2 Ampere). A 2C battery would need just half an hour to load 100 Ah, while a 0.5C battery requires two hours. The calculated Ah is the minimum amp hours your battery should have to power your device for that time period.

If you don't know the Watts or Watt-Hours, use the formulas below. The equation we would recommend using is: Charging Time = Battery Capacity. Discharging: Example: Battery AH X Battery Volt / Applied load. Avoid the steps that affect charging time and reduce battery life. For example, a 120-watt consumer is switched on in the car's lighter socket. Duration = Auto battery capacity (kWh) x 1000 / EVSE power (kW) x 1000. Efficiency of Battery = Generally it is 0.8, which is the max. If you increase either the voltage or the amps, you'll create more watts and generate more power. This battery life calculator estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used.

1800 watt-hours 9 hours = 200 watts (a 200-watt solar panel) Battery Amp Hours Regarding battery amp-hours, you need to think about how much power you hope your battery bank to store as a backup.

Fast charge is typically a system that can recharge a battery in about one or two hours, while slow charge usually refers to an overnight recharge (or longer). Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used. After converting the solar panel rating into amps per hour, divide the capacity of the battery by the converted rating of the solar panel. The charge time depends on the battery chemistry and the charge current. Got feedback? That page teaches how to take into account battery lifetime, Peukart effect, and end-of-life matters.
