Re: [WIP]Toyota RAV4 EV (2012-2014): Add CCS DCFC


As with QCC's JDemo, the car will have to be in Ready mode, as the BMS controls the contactors and the BMS will only close them when its happy. QCC's contractor was unable to persuade the BMS to close the contactors without being in Ready, though I'm planning on looking at this independently; as ...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

We're building our own version of a "rotor coolant delete manifold". This one can be used either as a straight up coolant delete (like the Rev U drive unit), or oil cooling can be added on for the folks that want it. We expect to have production ready units in stock starting in January.

Need help with LDU inverter firmware download/upload

Hi there folks,
I'm hoping to get a bit of assistance with an issue. I'm posting this on behalf of an acquaintance of mine named Shadi (who is from Jordan and doesn't speak English isn't very well). Shadi is working on a Mercedes B250e, which for those of you that don't know uses the same LDU as a ...

Re: Ford Ranger Inverter board Support Thread


About my previous post - "The first step (and most arduous) in the TIM replacement appears to be the removal of the connector so I'll get started on it."

I've circumvented this task and bought a new connector. If anyone's interested, cost is $168 + shipping.

Kia Soul EV

Looking for info on utilizing a Kia Soul EV battery pack for my 2000 Ford Ranger EV. I recently found a fantasic deal on one, and it seems like it would be a great fit for the project.
Ideally, I'd like to try and re-use the Kia BMS, which would allow for CHAdeMO charging and such, but I haven't ...

Re: Ford Ranger Inverter board Support Thread



But with the BCM removed could I run a 96s (390-400v) pack without running into issues? Or some the components not set up to take that kind of voltage?

Hi, and welcome!!
According to Siemens specs (Ballard) it can handle up to 385V.
The IGBT's are 600V and the capasitors are 450V
The voltage ...

Re: Ford Ranger Inverter board Support Thread

Very useful thread. I've been thinking about getting one of these boards for my ranger project (a 2000 with less than 7000 original miles). I haven't yet decided what direction I want to go pack wise, but I've been looking at an i3 pack that i can get for a pretty good deal. I'm wondering what the ...
