Mass-EV Project Plan
Now the final design is realised and research is being completed, the controller needs to be refined and tested.
Due to the new design of controller a full SPICE model
is being developed.
This full prototyping, including PCB testing of the development various stages, is time consuming, but necessary.
This is needed to debug and tune the controller and achieve the target of a low-cost, highly-efficient, powerful, robust controller.
The Class-D push-pull design of the new controller will now incorporate trinary (3-state) logic
This is the first controller to do this.
This means the controller can be very efficient using 3 output BLDC states per phase, but still be safe from shoot through by design.
Today we have a successful test of the class-D push-pull controller circuit.
This is a simple controller design which meets the design specifications required for a production controller.
Next stage is to refine, build and test the full production controller and move to in vehicle testing.
Over the last month a high speed link to be used in the cars is being developed.
This is almost complete and will be designed to work with the 3D display fitted to the cars.
In fitting with the philosophy of the project this is using readily available equipement.
In this case it is using standard PC networking
so this makes it very easy for diagnosis by the average computer user.
Today testing of the new controller on high power motors has started.
This means it is expected an electric vehicle will be on the road within a month.
The Software flywheel and Synchronous Torque algorithms are now integrated into the Hybrid controller.
The next stage is to revise the electronics to improve the efficiency of the Synchronous Torque algorithm.
So the final design of the controller is not far away.
After that a high power test bed in a real vehicle, which will be on the streets of Reading UK soon.
The implementation of the Software flywheel AC synthesis controller is complete.
This means creating a cheap controller is going ahead as planned.
Next stage is to create the full AC synthesis/BLDC hybrid controller
, which will start tomorrow.
