I get to talk a little about the electric supercharger that I'm creating. First off: This is not your typical ebay grade "Electric Turbo" that guarantees large amounts of horse power from a PC fan. This is a true, fully functioning Electric turbo that will be capable of compressing a substantial amount of air.
There are two markets I'm making this electric turbo for. The first and most obvious market is the performance sector. A lot of people would love to have instant boost when they want it, It should remove turbo lag and would be an amazing accessory for performance cars with large turbo's that take time to spool up.
The second market is the gas saving market. If I can get the electric turbo to keep 2-8 PSI throughout the entire power band; It should improve the engines overall flow considering that there will be no restriction on the exhaust side.
The E-charger is made up of 3 parts. The first is the control module which will be connect to the Vehicles ECU or OBD-II port. The control module needs to know the current RPM and the current TPS (Throttle Position Sensor). The reason the control module needs these inputs is because it tells the Controller how much power to push the electric motor at. This will be controlled by software I'm developing where users can manually enter how much power they want the electric motor to output when the TPS and RPM are at X. Below are pictures and a video of the control module:
Here you can see some of my "Fantastic" Electrical engineer innovation. I 3D-Printed a small board and attached two strips of copper wire. I then connected them to the positive and negative terminals of the Arduino which allows me to then connect the LED's to the copper strips and only worry about wires that Arduino controls.
*Phew - The second part of this whole thing is the controller. I'll spend very little time talking about this as I'm waiting for the motor to come in and haven't had a chance to play around with a specific controller. In an earlier, smaller prototype build (Will have a video at the end on this) of the motor and a controller; I was able to send signals to the controller via the Arduino board. When the Arduino board reads X RPM and Y TPS, It will send a signal to the controller to spin the motor based on the signal sent from the Arduino. I do have a controller in mind but I'm holding off just in case it'll change due to the custom motor.
Lastly! The third part is the part that sits under the hood. The electric motor, the compressor wheel, the compressor housing, and the cooling solution. Because I have a company building me an electric motor from scratch; I don't have a picture of the motor but I do have a 3D printed model of the proper dimensions of the motor. Below is a picture of the Compressor wheel, housing, and 3D motor model:
There will be a plate that I would need custom made to attach the motor to the back of the compressor wheel. I have a 3D model created for it BUT! I don't have it printed yet. The electric motor will connect to the back plate then the compressor wheel then the compressor housing. The electric motor will then have a cooling jacket which will be attached to a separate cooling system (work in progress). Below is a previous version of the Arduino set up to controller to smaller motor on an previous gear driven idea that I scrapped:
Hope you all enjoyed the write up! I'll make sure to keep updating the blog!
