How to find the power output of an electric car motor When talking about an electrical system such as that found in an electric vehicle the mechanical power given in watts W kilowatts kW or horsepower PS is calculated by multiplying speed RPM by torque the rotational equivalent of linear force measured in pound-feet lb-ft or Newton meters Nm.

How To Convert A Car Battery Into A Power Outlet Power Inverters Charger Car Usb

If the battery is 40AH a simple calculation will show that it will last for approximately 5 hours 42 minutes.

. The Nissan Leafs battery for. Amperage can be thought of as the volume of electricity thats generated but voltage can be thought of as the pressure of the electricity. The CCA of an auto battery is the amount of current a given battery can deliver for 30 seconds at 0 F 18 C without dropping below 72 volts for a 12 volt battery.

Every car needs a different power output battery size and more. Even though most car batteries are only 6 or 12 volts a 12-volt battery can produce as much as 600 amps. If you ran that motor for 30 minutes you would use 100 kWh of energy 200 multiplied by 05 of an hour.

A C is the Amp-hour capacity divided by 1 hour. The amount of current a battery likes to have drawn from it is measured in C. Your car battery is made up of 6 21v cells connected in series combined making a nominal 126v.

Most car batteries are 12V not really exact and also depending on remaining charge and current draw but there are many systems out there so theres not really a general answer. The average weight for a 12V lead-acid battery is 41 pounds. Therefore every car battery will have a different weight.

Dont be confused by terms like cca this is not the ah of the batteries. However what voltage your battery should be at any given time is dependent on. A dry-cell flashlight battery consists of an electric cell but larger batteries are made up of a group of cells that are connected to act as a source of direct electric at a given voltage.

Again the real results may vary since the voltage will drop off as current begins to flow. Car batteries operate on direct current flowing at 12 volts. However most of the info should be printed on the label and you can also generally go to the battery manufacturers web site and look at the actual specs.

A normal car battery might be 500 CCA. Shop High Quality Car Parts and Accessories Online or In-Store. Enter Your Vehicle Information to Find Parts That Fit.

A battery is a device that converts chemical energy into electrical energy. The higher the C the more current you can draw from the battery without exhausting it prematurely. Instead an EV buyer will likely want to install a 240-volt home charger which will enable much faster fills.

Lets say you have an electric motor rated at 200 kilowatts kW at peak power output. If the battery is 100AH a simple calculation will show that it will last for approximately 14 hours 7 minutes. So the C of a 2Ah battery is 2A.

Power Voltage x Current 12V x 500A 6000 W or 6kW. Restore Your Amps Roll On. To find the power of a car battery we multiply the CCA number by 72 volts.

If the battery is 250AH a simple calculation will show that it will last for approximately 35 hours 42 minutes. The way the power capability is measured is in C s. Batteries may weigh more or less depending on their size BCI group and age.

A cell consists of two dissimilar substances a positive electrode. Car batteries usually have CCA in the 300-600A range so over 1000A possible with a solid enough cable and terminations. Use a calculator to work out how long your battery will power your electrical device by checking the amperes on the label on the electric motor or device that the battery powers.

A decent hunk of copper wire - say the cable in good jumper leads terminated PROPERLY to rugged clamp on connectors and short cable length will give several times the battery CCA rating for a very short period. For example if the device consumes 5Ah and the reading on the meter is 20Ah divide 5 into 20 to get 4 meaning your battery will power your device for 4 hours. Your household appliances on the other hand operate at 110-120 volts of alternating currentmeaning that the current flows in alternating pulses at 60 MHz not a steady direct flow.

While the engine is running most of the power is provided by the alternator which includes a voltage regulator to keep the output between 135 and 145 V. Serving You Since 1979. Modern SLI batteries are lead-acid type using six series-connected cells to provide a nominal 12-volt system in most passenger vehicles and light trucks or twelve cells for a 24-volt system in heavy trucks or earth-moving.

Using Ohms Law again we can use the current rating and feed that into the following formula. Since wattage is V x A most car starter batteries are between 25 and 75ah and the voltage is 128v so a starter battery is between 320 and 960 watts. Ad What Are You Working on Today.

This is the max a battery can output for a short period.
