The charger has a fan built into it.
There is quite a large amount of space in the "hidden compartment" and it's not sealed off right now, so air isn't an issue.
Once everything is sealed up and finished off, I will check it after doing a charge, and see if it's warm in there. I don't think it will be. If it is, I can always add a small fan like you said.
The
Open Source Controller (the Cougar) arrived in the mail today.
I replaced my Curtis controller with the new Open Source controller. It's a little bigger, so I had to jam it down into the car a bit more to be able to close the hood.
The controller works great, although there is a small "shutter" when trying to pull away at really low speeds. That will be solved in version 2 of the controller.
The acceleration and speed with the 144V controller is better, but I am still trying to take things slow and test things before going really wild with them. Expect a full-blown test of the controller in a few days. (I still need to install the parachute brake!)
Also, having a 144V battery pack, and only a 72V charger is a bit of a bother. I have a connector to make a quick disconnect for an A pack and B pack, but I have to do some re-wiring to make it all work.
