eViking: Let's Wait fast

eViking: Let's Wait fast: Converting an ATV to electric is a very tricky thing. Solving one problem will cause three new ones. I started to work on a smaller version ...

Silent As An Owl

In Shanghai/China they have millions of electric scooters and kick scooters.

You have to be very vigilant, crossing the road because they are silent as an owl.

Electric drive is very popular in China and there are also more and more electric cars every day.

This is how they charge them.

Full Electric

Elektra becomes a full electric super silent camera car with 3Kw "grid power" on board to go for 202+ Km or 20h Arri M18 film light, or 100 Km and 10h M18 light.

Plus an Masse, das knallt klasse!

I killed my iCharger because..

One MOSFET was definitive killed by wrong polarity @40 volts.

But the new transistor could not save my charger__

Thanks Franz for the thick cold board soldering info. THAT was working.)

No more clicks from the Ukraine

This was the only electric car in Donetsk.

I hope my "ev-friends" from the Ukraine are ok.

Battery Bottom Balance Business

Buddy Balance

I am checking and balancing 22 Calb CA60 cells for a friend.

First I am checking each cell voltage and label it. There was one cell with a higher voltage.

While I was charging the whole pack in series, I already had to balance this cell with a 0,1 ohm resistor because the voltage was going up in the sky.

At the end I had a pregnant cell.

A sure sign for a dead cell.(

818

I want one.

How to double the spring pressure in a WarP9
It's long, it's tough. it's boring....but I had to figure out how to do it.
And all the failures show how it does not work.

Tesla Fuse Connection

Tobias  has a battery module from a Tesla Roadster.

The 18650 batteries are connected with a small wire to the main board that works like a fuse. When the current is getting too high because of a bad cell, the wire melts and this battery is out of the pack.

Today I visited EVTV Amsterdam.

He has his shop full with stuff you need to build your electric dream.

Rebalance

We have seen the red balance putty flying away.

 And we have seen the yellow balance putty flying away...

EV Sucks

EVDrive 19/2013 Downhill

Swiss Job

In a six hours night shift I was able to fix the front axle.

 ...and made a good test shot four hours later.)

Serious Problem

The good news is: She made it to Switzerland, driving non stop 188 Km,

 and up to 1200 m height NN (3.937 feet NAP).

But in front of the Hotel I had to drive backwards....and then this happened.(

I am still investigating what really happened. Both steering knuckles bent completely.

First the right and than, because of 600m depth in front of me I had to drive backwards again, and killed the left side.

I tormented her into the garage and hope to fix it before the next job...?!
