An electric car (not a hybrid) has been designed to operate from a 12.0 V battery bank with a total energy storage of 2.00x 107 J. a) If the electric motor consumes 8.00 kW, what is the current that is Do you supply the engine? B) If the electric motor consumes 8.00 kW as the car moves at a constant speed of 20.0 m / s, how far will the car travel before it runs out of power?

(i ) A EV battery has a capacity of 15 kWh. Assuming effective capacity used in the beginning is 85% and at end of life is 70% of capacity, what is the range that the vehicle (using 80 Wh /km) can support when the battery is new. What range will it support at the end of life? (ii) now assume, auxiliary power used is 500 W continuously and the average speed of the vehicle is 40 kmph. What would be the range in the beginning of life and end of life of the battery?

0:00 Hello.
00:02 So let's look at the parameters given in the question.
00:07 So we have, let's see.
00:15 We have potential difference.
00:17 V to be 12 volts.
00:24 We have energy 2.
00:31 2 times 10 to be 7 jules.
00:34 We got power to be, what is that? 8 kilowatts.
00:43 Now we want to find the current.
00:46 Let's talk about i.
00:49 Current, i'm going to be equal to the power divided by the voltage.
00:56 So each kilo is thousand divided by 12.
01:02 You can get a current.
01:07 So 8 ,000 divided by 12.
01:12 We have 6666 .67 emper.
01:19 Let's look at 2...
