A comparison with various electric motor/e-Axles and BEV powertrain.

And the part two from the previous post - showing comparison with various electric motor/e-Axles and BEV powertrain, including my best estimate on what the new E-Ducato is using. Please - i draw the reader's attention to the slides where i show the Physical adhesion Traction limits, for a single axle, where provision of more axle torque that there is available grip - should make sense/non-sense of many misconception of needing bigger torque and bigger power values.  

Project Justification - Why not just swap in the E-Axle motor from an EV car hybrid or Battery EV? - Torque comparison with diesel powertrain.

Explaining what the concept is and is not.  Since the beginning of this project i have been troubled by the issue of how the concept is similar to but crucially different from doing an EV conversion. When i say 'troubled' i mean by way of finding suitable technical knowledge for my project, because my project requirements are not the same as doing an EV conversion. The most important distinction being the need for a high reduction gear combined with the disconnect. Firstly, is to mention doing a hybrid i.e. retaining the ICE while adding an electric motor and transmission where there was before none (only freewheeling hubs) - this is already a really big challenge for a DIY home project. To be honest, it is too much difficulty, expense and perhaps impossible to have such design safe or legal for road use. Hence, my approach all along is to have a design which is only for off-highway use. It is on-demand and only for low speeds, and should not be dependent upon high voltage EV h
