Sub Parts
Diode
The diode must be firmly and correctly mounted to the heatsink. The diode has a 1/4" stud which passes through the heatsink but does not touch the heatsink. A shoulder or insulating nylon tube must be placed over the stud where the diode passes through the heatsink. This is important so the diode does not electrically make contact with the heatsink. Additionally, 2 electrically insulating, but thermally conductive pads (or mica) must be used on both sides of the heatsink to prevent the diode from making contact on either side of the heatsink. See photos below for how to mount the diode:

Snubbers
Solder together one lead of the .47uF, 500V capacitor and one lead of the 22 ohm 1 watt resistor. Put heat shrink tubing around the other 2 leads and crimp on ring terminals and solder the crimps to the leads for a better connection. The snubbers are then placed across the two contactors.
Low Voltage Interconnects

Warning & Tips
Batteries can be dangerous and can cause serious injury or death and should only be worked on by persons qualified to do so. Both energy hazards from arcs (shorts) and electrical shock can cause serious injury or be fatal with a battery pack of this size. Battery packs are always live and cannot be shut off! The following are safety tips to help prevent arcs and shocks, but they are only tips and should not be taken as a go-ahead to perform work on battery packs. Extreme caution must be taken as it is very easy to accidentally set something on the battery without thinking or drop something and cause a shock or arc. Hire a qualified electrician to help for this part if there is any doubt.
- Remove all jewelry, especially gold, before working with batteries.
- Do not allow metal to come into contact with the batteries that could cause an arc (best practice is to not allow any metal near the battery at all.
- Use only fully insulated tools around batteries, especially in tight spaces (available in the electrical department in most hardware stores.)
- When wiring batteries, be sure the other end of the wire will not accidentally come into contact with any other part of the battery or metal frames. Taping or otherwise protecting the ends of wires is recommended.
- Wear rated rubber electricians gloves and outer protective gloves. Electricians gloves are not fail-proof and every effort should be made to only touch insulated tools even when wearing gloves.
- If electrician gloves aren't used, only one hand should be used so that a shock will not pass current through the heart.
- Always wear gloves when working on batteries (preferably rubber.)
- Install the jumpers in 48 volt sections and then connect those smaller sections together at the very end. This way voltages higher than 48 volts are only handled when installing 4 jumpers instead of 16.
- Even though the batteries are sealed, it is still possible for them to leak and splatter acid, especially if they are just charged, heated or an arc occurs. If a leak occurs, use baking soda to neutralize the acid and properly dispose. Eye protection is a good idea.
- Orient batteries in the tray to avoid terminal contact with any bolts or any metal pieces.

HV (High Voltage) DC (Direct Current) Warning: Traction Battery Packs, Motors, Chargers, and other HV sources could cause serious injury or death if proper precautions are not taken while working on or around such High Voltage Direct Current sources. Use this information at your own risk: There is no warranty expressed nor implied and we are not liable for any of your past, present, nor future actions. Even should you perform these modifications to the letter you could still damage any number of components in your vehicle causing it to no longer function. Even if it appears to function properly your actions may cause it to self destruct with collateral damage to surrounding properties other than your vehicle. By utilizing these ideas and instructions in an attempting to enhance national security, reduce gas consumption, vehicle "emissions", your carbon footprint, or smog, you do so at your own risk & peril. Warranty: In performing some of these modifications you may void your warranty with the vehicles manufacturer. See also our My wiki:General disclaimer |
