I look forward to this being my Only project 😎😎😎😎😎😎😎😎😎😎😎😎. Giant RC car 🚙🚙🚙. With 500 Horse Power 😎😎😎😎😎😎😎😎😎John JonesModeratorJuly 13, 2023 at 8:03 amPost count: 12886
Time to wrap my head around this project!!!!!! 😁😁😁😁😁😁😁😁
I’m hoping I can get some guidance from Glenn and Will on this one..,,🙏🙏🙏🙏🙏🙏. They work at Rivian😎😎😎😎John JonesModeratorJuly 13, 2023 at 8:04 amPost count: 12886
I’m starting to worry about these cells I have sitting around???! Should they be on s trickle??John JonesModeratorJuly 14, 2023 at 8:27 amPost count: 12886
Looks like EV west puts the batteries behind the seat and where the gas tank was…. I’ll see if I can fit them all there🤞🤞🤞🤞🤞🤞🤞🤞
I’m gonna order a sheet of 20gauge to fab some boxes out of👍🏻👍🏻👍🏻DaKineParticipantJuly 14, 2023 at 9:57 amPost count: 178John JonesModeratorJuly 14, 2023 at 2:52 pmPost count: 12886
That shit is cool!!! full size tamiya!!!
Time to do some measuring….8-) See where I can cram batteries and make boxes to enclose them… 😎 I wonder if some sort of spacers will be in the crates?? I am sure they probably have some way to space and connect the batteries??John JonesModeratorJuly 17, 2023 at 6:10 amPost count: 12886
I’m getting batteries out today !
start stacking 🔋🔋
order a sheet of 20 gaugeAudrey JonesModeratorJuly 18, 2023 at 12:56 pmPost count: 1486
Today I put batteries where we’re thinking in the car!!!! Thinking a big box for 9 in the back, then a smaller box for 4 in the front and then one more behind it… I wonder where EV west puts that last battery…?? each battery weighs 40# so that’s 360# added to the back and 200# added to the front 👌🏻John JonesModeratorJuly 19, 2023 at 6:14 amPost count: 12886
Hell yeah!! I like it. Simple and easy..
Time to order some sheet metal!!!!👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻 The EV boxes were aluminum.. I’m gonna do steel😎. They were also $1000 each🤫🤫🤫🤫.
gonna open these boxes and see what I have to play withJohn JonesModeratorJuly 19, 2023 at 6:49 amPost count: 12886
I think I need to 100 💯 mock this shit up…. All the wiring, everything 🤔. I bet it will affect my box sizes too…GlennmossModeratorJuly 19, 2023 at 4:33 pmPost count: 319
Looking good! Here’s a general list of things to consider:
VwfoolParticipantJuly 19, 2023 at 7:27 pmPost count: 873
- Battery management system (BMS) – do you have one yet? This measures the voltages of all the cells in the battery pack and keeps them at an even level. You will need to run wires from each battery module back to the BMS.
- Contactors and fuses – you will need a contactor to switch the HV energy off between the battery and the drive unit. These need to be kept in a Water/dust proof box.
- Cooling system – The drive unit will need to have some coolant cycling in it to function. You will need a small radiator and reservoir tank. Batteries can be kept air-cooled but would be better with some type of cooling.
- Motor controls – You will need an electric accelerator pedal, a CAN display screen where you can select drive modes, CAN harnesses. For the small tesla drive unit, we had to buy a new control board because the controls are locked to the VIN of the vehicle it came out of. I don’t know whether the large motors have been successfully “hacked” where you can control it without needing a new control board.
- Charging – you will need a J1772 outlet mounted somewhere and a charge controller. The charge controller will need to be wired to your BMS and your battery.
- Safety –
- Insulation is always important. Get high voltage safe gloves for attaching the battery modules in series.
- Do not work on the battery alone. Have a second person present when wiring up the battery.
Sounds like a huge pain in the ass to me. I am also lazyJohn JonesModeratorJuly 20, 2023 at 8:06 amPost count: 12886
Thanks Glen! I’m gonna need some guidance 🙏🙏🙏🙏
We looked in the boxes yesterday.. I have what looks like a charger x2and a Dc to Dc converter’s x2 Then some display, a few fuses and holders, and a bunch of plugs and a plastic box to put some water tight stuff in and some battery cable and ends
and the cutest little 12v heater… we gotta try these in a bus!! I’m gonna hook it up on the bench and see how well it works…
