Hmmmmm......

Is this regarding our conversation a few weeks ago...

I think I can get the shell, maybe the motor, and perhaps the batteries... but the build isn't up to the part that I can't figure out yet... the controller.

Do I go all golf cart and run sans charge-controller, or do I still need it?

[ghosthunter]

(left to right) pot-box is like throttle, motor controller gives the right current to the motor based on throttle input, and the contactor is just a big relay (power switch to the high voltage circuit)




the small relay gives power to a special terminal on the controller that turns it on

Well, partly... but I didn't go out of my way to find an ev-beetle conversion just to prove my point that an old beetle would be a good start for an EV project. I just stumbled on it while I was checking on another topic of interest.

Well, you can run the car with the throttle like a light switch, either full on or off. It would be interesting trying to park it in your driveway.

So yes, you'll need a motor-controller to moderate the amount of power from the battery to the motor to have some sort of speed control over it.

As for recharging, its mentioned that a proper battery charger will give the battery pack longer life since it won't experience over-charging.

BTW, golf cart motors are too weak. You'll want something stronger.

And I'll definitely want a better charging strategy than golf-cart style "open-everything-up-and-plug-in"... or I'll be suffering the same issues as the electric bus operators at SM MOA suffered before they converted to gas.

Hmmm... controller packages from the US cost quite a bit... but just maybe I can get it cheaper if I have someone hand-carry the stuff down here...

Hi, I am also interested in doing EV conversions and I agree the prices are too expensive. If we do it as a group then we can lower the cost through bulk purchase and economies of scale. I am thinking of starting an EV club.

o ayan, EV club daw

electric car advocates put your money where your advocacy is -- MONEY DOWN

buy electric motors and batteries to build your EVs

anybody?

come on open your wallets... don't be shy

just came across this video from youtube, an electric drag racer. actually makes sense 'cause an electric motor is supposed to give out huge torque which you will need in a drag race.

so whatever happened to the PH electric car scene?

i'm really really tempted to get a cheap used suzuki alto, rip out the engine and put in electric bits

Hangat walang battery na mabilis ma charge at matagal magamit e hindi mag boboom ang e car.. sana may ma invent na at super affordable.

it's not gonna be super affordable coz batteries are expensive. not yet at least

charging time for lithium-ion is very decent, especially the bottom half i.e. zero to around half-full can be charged very rapidly without detrimental effects

cycle life and calendar life for li-ion is very good already. 8 years no problem. after that you could probably use it for home electricity storage

I think dapat mas mabilis pa. Parang standard petrol lang na kinakarga for a few minutes and can run for alot of hours.. it that happen im sure e car will boom.

yep that'll get invented eventually. but for now this is what we've got. for daily commutes a "slow" 2 or 3 hour charge at night is really good enough

charging time isn't the limiting factor right now, it's COST. batteries are expensive. that's why Elon Musk is building the gigafactory

If you want to perform a conversion, you can talk to the guys at MD Juan who do the E-Jeep. I think they offer conversion packages. Or they did, at least the last time I asked. They've rolled out another series of E-Jeeps over the past year, so they may still have the parts for it.

There are several other local groups building E-trikes and E-Jeeps. Some specialize in controllers, others motors, others batteries... the scene is small, but actually growing.

One of the more interesting ones is this:

Their "Agila" electric bike has a pretty powerful motor. 18hp equivalent, if I recall, and it's powered by lithium-ion batteris. Heavy-arse bike, but it's the fastest electric-bike I've ever ridden... easily equivalent in power to a 250cc or higher bike, with instant torque.
