Mac & Mac Electric & Electric Vehicles of Washington's goal is to provide high quality electric & hybrid vehicles at affordable prices which maintain a high level of safety and comfort. Our state licensed electricians and engineers have spent years developing the most efficient systems using the products available yesterday and today with tomorrow in mind. We want to get you on the road in a smog free, carbon free vehicle, which you can rely on as a daily driver for getting to & from work, as well as running your normal errands. Visit our On-Line Store!

We strive to provide the best quality parts at the most inexpensive prices by constantly shopping around with our well established vendors as well as performing our own research and development on our own custom AC control systems that we develop here in house. Electric Vehicles of WA can supply you with brand name motors & controllers such as D&D Motors, G.E., Baldor Motors, Zibo Boshan Super Motor Company (Being), Alltrax Controllers, Advanced DC Motors, Curtis Instruments, Zilla Controllers or any combination of these and our own in house designs.

We work closely with the Vehicle Research Institute at Western Washington University to develop the industry standard of vehicle designs in efficiency.

Our Hybrid power systems utilize only the best DC & AC generator technology developed by Ample Technology in Seattle.

Our suggestion in building any EV/Hybrid electric vehicle would to be to build the lightest and most efficient vehicle possible while maintaining the strictest safety standards with a dash of comfort. Some things to consider are:

Type of battery & battery location - The cabin space in a vehicle should not be the primary place for mounting equipment. However electronics parts & battery life will be greatly extended if parts are kept out of extreme conditions. If batteries are mounted under the front hood, much care should be taken in order to seal the machinery compartment. Sealing the machinery compartment with a rubber seal around the hood opening and blocking off the original air cooling entry grill, as well as the underside of the machinery compartment will allow you to keep the batteries at a controlled temperature as well as keep things clean. If the batteries are to be mounted inside of the cabin they should be enclosed in ventilated battery boxes which will keep the batteries at a controlled temperature and also contain the batteries in the event of an automobile accident. The batteries are the heart of your vehicle.

The Hybrid - A small generator set is suggested. However, we would suggest, Do not think of the gen set as a means of a constant power source. As the more weight you add to your vehicle the less efficient it becomes. We would suggest a gen set which can be run in conjunction with the battery pack in order to extend drive time while you still have battery power left in your pack. However also a gen set sized in which, if your batteries were completely depleted, you would not be able to run at full speed on the gen set, instead, perhaps at about 45 mph. More of a last resort, Get me home, my batteries are dead scenario.

Best type of vehicle (size) - The best candidate for an electric vehicle conversion is a small, lightweight vehicle capable of handling the speeds you intend to reach. It can be a car, a truck, or even a motorcycle. Any vehicle can be converted to full electric but larger vehicles require more batteries, which increases weight and decrease range.

Transmission - Manual transmissions are the simplest to convert to full electric. Some require no modification or additional items to work correctly. Older automatic transmissions may require a vacuum pump or some creative wiring. Modern automatic transmissions have computers in them and require signals from the engines computer to operate. This can make them difficult to modify.

Power steering & brakes - Manual steering and brakes do not require any attention when converting to full electric. Power brakes require a vacuum pump and power steering requires a hydraulic pump. Both of these draw power from the battery back and decrease the potential range.

Heating & Air Conditioning - The original heating system can be replaced with an electric or propane heater. An electric system draws power from the battery pack and decreases your range. A propane unit requires storage for a propane bottle and venting. Both are reasonable choices and it boils down the preference of the customer. A plug in ac heater can be set up on a timer to pre-heat your vehicle in the morning before your commute.

Radio / Stereo - Since the vehicle keeps all of its original auxiliary system a stereo is very practical. A simple stereo with 2 6” speakers requires very little energy to operate. It is an ideal system for a full electric vehicle. Large speakers, sub woofers, and amplifiers require a great deal of power and would need their own battery pack to operate. For this reason, large stereo systems are not suggested for commuter electric vehicles.

Suspension - Most vehicles will increase in weight when converting to full electric. The motor, electronics and batteries usually weigh a little more then the original engine, acessories, and fuel tank. Some vehicles will require suspension modifications to retain stock ride height. This can be accomplished by upgrading springs, adding air shocks or a variety of other methods. The solution is usually unique to the vehicle and application.

Range - Unfortunately, the usable range of an electric vehicle depends greatly upon many factors. Items such as battery age, drive train, weight, and driving habits & driving conditions are only a few of the things that effect how far an electric vehicle can travel on a single charge. A small vehicle like an old VW Beetle or a 1960’s coupe with a 72 V AGM VRLA battery system can obtain a range of approximately 40 miles. This may not be true for all vehicles of this type and can be a bit different even between two similar vehicles.

Batteries -
Lead Acid
            Flooded (wet) cell lead acid batteries are the most common type of battery used in electric vehicles. They are cheap to produce, fairly durable, and have a decent life span. Unfortunately, because they contain liquid acid, they can make an electric vehicle uncomfortable to drive and require proper venting during use. For this reason more and more electric vehicles today use Gel Cell or Absorbed Glass Mat (AGM) Valve Regulated Lead Acid (VRLA) batteries. Both are more expensive then liquid cell lead acid batteries but they weigh about the same and are sealed. Gel Cell batteries require special chargers because they can become damaged if charged incorrectly. AGM batteries use a very simple charger and are much more durable then Gel Cell batteries.

Other Battery Types
There are many other types of batteries that are capable of powering an electric vehicle. The majority of them are more expensive then all types of lead acid batteries. Some are minimally more expensive and offer some benefits over lead acid batteries but sacrifice durability or life expectancy. A few of these batteries are possible candidates for electric vehicles but can increase the cost of the vehicle by 20-50%.

Voltage
The voltage of the system ultimately determines the available energy for the motor to use. A higher voltage system gives the motor the ability to use more energy in a given amount of time. This translates to quicker acceleration times and higher top speeds. It does not directly affect the range of the vehicle.

Number of Batteries
The number of batteries in a vehicle can determine several things depending on how they are connected.  Most of the time space dictates the maximum number of batteries allowed and voltage requirements must be met before range extension can occur. For this reason electric vehicles have historically been range limited. Recent advancements in battery technology and component design give electric vehicles a great deal of potential.
