Close look

Written by admin. Posted in Electrical Enclosure

Here is the Evision circuit board that measures voltages, currents, and steals some isolated power for the controller. It sends out the data on a fiber optic link (blue fitting/black cable)

The Fat current sensor resistors are out of view below the FR4 sheet.

More stuff keeps fitting in, but it is about full now.

The wired result

Written by admin. Posted in Electrical Enclosure

I am using semiconductor pre-charge devices along with the power resistors seen above, in gold color and with cooling fins. They will get little use so they will not be hot normally. In the case of a fault, we will sense it with thermal sensors that can generate a response.

Here is the finished contactor/distribution box:

I liked the powder coating on the battery pack so we had to make this match. It turned out too nice…

Where contactors will go

Written by admin. Posted in Electrical Enclosure

These large contactors (in the white enclosure) that came with the motor Inverter will be relocated into this odd shaped space.  

We will make an aluminum skinned box to fit. We will use these 2 embedded captive nuts as a mount point on one end and the battery box mount plate on the other.

Fuse, contactor, and distribution box

Written by admin. Posted in Electrical Enclosure

Here is the rough outline of the Fuse box. Battery output cables pass through the wall of the battery box directly into this box.
