Re: Francisco's Electric Pajero

After getting the model of the bottom I can now start to work out how much space I have for the battery pack. Here is a picture of the model with the battery pack. https://photos.app.goo.gl/E6qJgNRy54eqaP6P9 . I decided to use the E63 LG batteries. Battery specs: Nominal Voltage : 3.6V Nominal Capac...

Re: Francisco's Electric Pajero

I have sent some of the parts for the gear box and the transistor pack coolers. It turns out I can get them made in China and shipped for about the same of what the material would cost me to buy. So now I am waiting for the parts. In the meantime I figured I would work on the batteries. The biggest ...

Re: Francisco's Electric Pajero

Your comment about catching up with php got me thinking about the pictures. I wonder if I can put the picture as a HTML picture link. So here is a test. So here is a picture of the inverter cad model. <img src="https://photos.app.goo.gl/GADGHhgUx2t3LvvDA" class="postimage" alt="Image"> See if this w...

Re: Francisco's Electric Pajero

The expected "pulling" capacity will be about 30% higher than the original maximum pulling capacity in 1st gear (peak output of the petrol engine is around 4000rpm, around 35kph in 1st gear), except it will be able to keep pulling with that force all the way up to about 150kph. I guess if I limit th...

Re: Francisco's Electric Pajero

I have a few more pictures. Here is the donor transfer case (Toyota Prado 1996-2002 5VZ V6) It happens to have a ratio of 2.566 for low range which happens to be almost right for the ratio I need. Here is the picture of the transfer case (before) https://photos.google.com/share/AF1QipO7r3NThX6VI89qR...

Re: Francisco's Electric Pajero

I haven't got to the batteries yet. But I know the problem. I have two possible solutions: 1) limit the output power to what the batteries can take and will depend on how big a battery I end up having. 2) limit the output power depending on the battery temperature and assume I will not be trying to ...

I have tried to find the attachment tab but I can not find it anywhere. There is an image tab and a picture tab at the top but it just puts this Image or this [image=][/image] and I still can not find anywhere it will ask for a file name.

Francisco's Electric Pajero

Brief history of the project; The car is a 2002 Petrol Pajero. I bought it new. The car is getting old and starting to cause problems. It burns oil, the aircon is making some bad noises ... But apart from that the body is in reasonable condition. I wanted to buy an electric car when I get a new car ...

Re: Which Motor?

I am hoping I can make them for less than 10k for motor and inverter. I am still working on the system so I am still not sure how much it will cost to make but I am hoping it will be around 7k or maybe a little less.

Re: Which Motor?

The motor weighs 50kg and the inverter will probably add another 10kg. So I am expecting a total weight of about 60kg.

Re: Which Motor?

If you run the motor at lower voltage you will get less power. The torque will be the same but the max rpm will be less. I have made a page that can help you to calculate the power of the motor you need depending on what you want the car to do. It is a bit rough and I have not checked everything tho...

Re: Which Motor?

So for the graphs you have the Chinese graph is clear as to what you are getting. What it does not tell you is what voltage you need and you will need this info for choosing the inverter. The HPEVS graph tells you it runs of 96v but the vertical scales are not clear so you really can not tell for su...

Re: Which Motor?

Generally you will have two parameters for a motor: Torque and power/RPM You can calculate the power as follows: p= 2*pi*rpm*t/60 where: p = power in watts pi = 3.14... rpm = motor speed in rpm t = torque in Nm Electric motors tend to be a torque machine meaning that the size of the motor depends on...
