The Aphid project The name Aphid comes from the small bug that live among the leaves in plants. The Swedish name is “bladlus”, can be translated as leaf louse, sounds like the perfect name for when...

This post is just a draft, there will be more schematics and diagrams coming… The main contactors will make it possible to make the HV-system powerlkess during all drive states. This is an importa...

This post is just a draft, there will be more schematics and diagrams coming… The battery will be built of modules from a donor EV, which type will be determined by the availability. Hopefully we ...

The intention with this post is to collect some info on the Nissan Leaf waterpump for the cooling water. From what I’ve found it’s the same pump also used by Tesla EV’s. The purpose of the electr...

The direction controller is a small PCB used as a driver interface to select drive direction. It does not contain any logic, just enough to make 3 buttons and 3 LEDs available to the driver: For...

This post will try to collect the main requirements on the DIY VCM. Even though it likely never will be formally tested, it is a good thing to get a grasp of what is needed before finalizing the de...

The safety systems are designed to protect against two main cases: Unexpected torque from the motor leading to unwanted acceleration or braking. Access to the high voltage rails. The same me...

The firmware of the VCM monitor microcontroller is intentionally very simple for two reasons: Less code -> less bugs Les functionality -> not as much updates needed. The application wi...
