EV Parts

Here's what  I've got so far

Battery Terminals

these clamp on the 15 batteries i will have and using the #2/0 ga wire, allow for a secure link between each battery

#2/0 Ga Wire

Weighs like 30 lbs total. It is 40 ft, and is used for all the high current wiring. The high current stuff is everything that needs the 120v of batteries to run such as the motor and controller. I'll use much thinner wire for the low current stuff like the gauges since they only use the 12v car battery.

120v Quick Charger

This charges the 120v battery pack from an outlet the red and black cables attach to the + and - of the 120v battery pack and the plug in will go to regular outlet. It weighs like 50 lbs.

Throttle Box

This is essentially a lever the attaches to the accelerator cable, so when you push on the accelerate pedal the little arm moves back. The faster you want to go the more the arm moves right. The Throttle box wires up to the controller, and the controller tells the motor how fast to spin based on the resistance from the throttle box.

Contactor

This safety feature is essentially an on/off switch, there is no way to turn the car on, or off without it going through this. It is wired to the ignition, batteries and controller, so that when i turn the key, everything turns on, but if something were to malfunction, the controller has the ability to shut everything off with the key still ion the ignition.

Voltmeter

This is essentially the fuel gauge when I'm fully charged it will say 120 volts as i drive, this ill go down to 0 when I'm out of power

Ammeter

This shows how many amps are running through the system. It is proportional to how fast im going since more amps are released for more power. It is simply there so i can make sure the batteries are letting the right amount out. For this to work, it must be wired to the shunt.

High Current Terminals

This connects all the components other than batteries to the #2/0 ga wire and 120v system. This includes the motor, controller, contactor and more.

500A Fuse

This is another safety feature. It breaks and shuts off the car if too many amps pass through it

Shunt

This detects how many amps are coming through in the current and if wired to an ammeter, displays how many amps

12v Battery Charger

Since i no longer have an alternator to charge the car battery, i need to manually charge it. To do this i wire the black and red cables to the 12v battery and the plug in in to a regular outlet. Since i also have the 120v charger, ill probably plug them both into a surge protector and then plug the surge protector into the outlet.

Controller

This is what i built, it is like the brain. It tells the motor how fast to spin and shuts it off if its too fast. There is plenty of info a few posts back on how i built this. It probably weighs around 20 lbs.
