Electric Vehicle Motor Power Calculation

Speed is the top speed of the calculation.

Electric vehicle motor power calculation.

Motor efficiency is the efficiency of the motor. Only one problem that much electrical power put into the motor could easily destroy it rather quickly. The main reason is that li ion batteries have higher. Down the right side of the page you ll find your car s make and model from the drop down box then your electric motor type in the second drop down box your batteries in the next and so forth.

In the case of an electric car its power output depends on the size of its motor its volume and the wattage of the incoming current. 1 ft lb f 1 356 nm. T ftlb torque lb f ft. So its power output is derived from its maximum energy transformation capacity.

P hp horsepower delivered by the electric motor hp. Motor torque calculations for electric vehicle saurabh chauhan abstract. T ftlb p hp 5252 n 1b. So the battery s storage capacity and the.

It is estimated that 25 of the total cars across the world will run on electricity by 2025. There is no petrol to provide power. Torque in imperial units can be calculated as. All of the power must come from the batteries and electric motor s.

Electrical motor power velocity and torque equations. However this peak power is only required during fast acceleration and not during coasting. Individual battery cells are grouped together into a single mechanical and electrical unit called a battery module the modules are electrically connected to form a battery pack. T inlb torque in lb f.

P f t v η 1. This calculator provides an estimate of what size electric motor is necessary to propel a vehicle on flat ground or up an incline at a certain speed. There are several types of batteries chemistry used in hybrid and electric vehicle propulsion systems but we are going to consider only lithium ion cells. Ev calculations how to calculate power how to calculate rpm electric vehicle power electric vehicle rpm the given link is for coefficient of drag for di.

P engine power w f t total forces acting on the car rolling resistance force gradient resistance force and aerodynamic drag resistance n. The common in the field estimate of kw power a 9 motor can handle for short periods is 100 kw. T inlb p hp 63025 n 1. An important component that is an integral part of all electric vehicles is the motor.

V velocity of the car m s. The calculator was designed for dc motor systems so if you re planning an ac conversion it won t be helpful. N revolution per minute rpm alternatively. So using the above formulas 144 volt system should be limited to about 700 amps and the 288 volt system to 350 amps.
