Concept for downsized full hybrid
Hello everyone,
I already posted about a university project on hybrid cars that I'm working on a couple of weeks ago. We're now one step further and are trying to develop new hybrid drive concepts. The goal is to develop a downsized version of a full hybrid that makes it possible to drive short distances (3 miles) at low speeds (around 10 mph). The reasoning behind such a system is that it should be possible for drivers to use their cars in zero emission zones (these zones are increasingly discussed and implemented in European cities).
There are a couple of ways how such a downsized HEV could look like. We could either develop a small in-wheel motor, have an electric motor propelling the axel that is not the drive axle, or have an electric motor connected to the transmission (similar as in mild hybrids). This is what I can think of, but there might be other ways of doing it. Since costs should be kept at a minimum, there might be benefits of not connecting the electric motor to the driveline.
I've seen that some of you have been working on electric conversions, and I was wondering what you think of this downsized full-hybrid. Can you think of other ways how our goal (short distance-low speed EV) could be reached?
Would be great to get some insights from you. There's a lot of information about such concepts out there but I haven't come across a lot of people who actually tried and managed to either convert their cars completely or add an EV mode themselves.
