Some questions about Electric Vehicle

[Magnethos]

If I want to convert this car into a Electric Vehicle...
How much energy do I need?

Some days ago I searched for info about the energy conversions.
I read that the HP (horse power) of my car is 100.
So, in watt is 100 * 736 = 73600 Watt
(I think that the HP is 100, I'm not sure)

So... How much amount of energy could need a minicar like the one that I show in the picture?

How can I calculate the amount of energy that I need to run the car?
I think that I need to calculate the weight, max speed and other factors to know how much energy needs the car

In this video you can see better the microcar:

How much energy you will use when 100hp car - its depends about your driving style and where you will drive,
As I remember 100 hp = 74.57 KW but does not matter right now,
1J=1W/s. 1Wh=3600 J and so on ...
Before to start with 73.600W electric car ... khm...khm ... how old you are? 
Lets suppose you will use 72V system - then your motor and controller both need to be able for current like 1.022A  - it is when your right leg is fully straighten on the throttle pedal 
Lets supose you will choice 144V - then amperage you will need is ca 511A,
When 400V - then 184A  ... this is more realistic ... but are you able for these kind of figures in real life?
Even 144V of DC can kill you instantly - I really hope you will not tuch,
When Batteries are common lead-acid  75 A/h - then you can drive this electric car ca 15 min when heavy racing ;-)
And you will need "only" 33 series common car accus 

Best regards,

Im back from garage - one 75 A/h lead acid battery weights 28 kg,
33 x 28 = 924 kg total  ... my God 
But ok - I have several Lithium accus too ... just a minut ... will back soon
so ... 5000 mA ( 5 A/h)  37.0V  Lithium polymer 10s pack weights 1.2 kg cost was ca EUR 550,
I have tens of similar packs 5s, 6s, 10s and 12s - lot of money need to be spent if you like to do at least something 
OK, this 10s pack is able to:   108A continiuous , 147A sustained and 245A bursts
To have 185V we need those units  5 series, to have at least 100 A/h we need 20 parallel ...
Total 100  amd ...  again 1200 kg,
Now we have 100A/h , 185V and amperage could be more than  2000A continiuous!
But now we calculated  for 185V - means at least 400A for get 100 hp ...
Even if we find adequate controller - we can drive not long time with this car - a quarter of hour maximum ...
Lithium polymers you never can use up to end - comes fire!

hereby I give up the crown,

Hello

For this lightweighted car 10 KW might be enough for the town.

Other Cars like aixam came with 4 HP

Of course, self-evident, but Magnethos asked about 100 hp
