The one EV car we currently have (have 2 vehicles that run on hydrogen also, 1 Ethanol & 1 Biodiesel) we converted from a vw bug & is free to charge. As The Ranch is completely off the grid all electricity comes from solar panels & wind generators, which we also built ourselves.
However I did charge up at Costco charging station in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00
Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I've converted 3 of my own cars (a datsun truck, ford van, & a vw bug) & a few for neighbors. I've also converted cars to run on hydrogen, ethanol & biodiesel, by far EV is the easiest.
If you’re interested here’s what it would entitle…
- The engine compartment is first cleaned out of any gasoline components.
- Electric components are then installed in exchange.
- A battery bank is built & incorporated.
- Existing starter & driving systems are connected.
- Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.
- The system has normal automotive top speeds & acceleration, typical to the vehicle your modifying. If your top speed was 85 mph & your acceleration was 1 mile per min, then this will be what your left with after the conversion.
The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.
Typical tools, hardware & supplies are used, making access to parts available for all.
Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.
Project lengths range from 1 day to 1 month.
If you’re interested I wrote a guide on it which is available at www agua-luna com
My last EV conversion ran me about $1400. Everything is available online. Here’s a list of what you'd need...
Advanced DC Motor
The motor is an 8" Advanced DC series-wound motor. It weighs 107 pounds & is rated at 68 peak horsepower. These motors are available in several sizes.
The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum & is pre-drilled with bolt hole patterns for both the motor & transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission & motor. Adaptor plates are available for many cars.
DC Motor Controller
The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis & DCP.
The potbox is a 5K ohm throttle between the controller & the accelerator, similar to the way a sewing machine pedal works. The potbox's lever arm is attached to the existing accelerator cable.
An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.
A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood & can be switched both off & on from the drivers seat with an extension or cable.
The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.
A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high & low power configurations.
A relay that keeps the circuit open so nobody will inadvertently drive off with the charge cord plugged into the car.
The DC/DC converter is similar in function to a gas car's alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.
Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online & on-site workshops, seminars & internships to help others help the environment.
