Electronic Components

I wasn't aware the switching devices were the problem with civilian hybrid vehicle drive systems. I always got the impression it was the overall unrealistic cost and unnecessarily complicated way they handle the power that was the problem. Maybe the manufactures should take a look at the industrial application drive systems.

I have seen electric drive systems that drove 2000 peak HP motors on mining loaders that were about the size of an office desk. I don't know who made them but they weren't American! 100 electric HP in a vehicle can be compared to over 200 (or more) as advertised IC engine HP when given an honest head to head comparison. So the actual drive and motor control system does not need to be physicaly huge.

What I have seen of civilian Ev's and Hybrid drive system design issues so far is the retards that design them over complicate the systems to a point of failure and unrealistic practicality of both use and long term reliable operation. To much tech is used in a system that just doesn't actually need it. They use the 'It has to built this way to be reliable and safe' argument yet industrial and mining trucks and heavy machinery have been using simple, basic, efficent but very bigt hybrid engine/battery/electric drive motor systems for decades with outstanding results. And on absolutely monstrous power levels and working life expectancies compared to what is needed by a civilian vehicle.

The hybrid vehicle manufactures need to go and talk to the engineers that design the drive systems for mining trucks and mining earth moving machines. They know how to handle monstrous hybrid system power with high efficiency and long working life spans.

On/Off, Faster/Slower, Forward/ backward. That covers every driving situation I have ever been in so why complicate it any more than that?

Just my opinion.

Any improvement in the drive electronics for EV's and HEV's will be welcome, as long as it is economically beneficial. Electric motors and drive controllers very efficient right now. GaN seems to be only an incremental improvement in an already mature technology. This is fine, but what is really needed is a revolutionary improvement in energy storage technology.

The REAL boon to EV's will be a practical* battery technology that can provide the same performance as the gas tank on an IC vehicle.

* reliable, inexpensive, light-weight, non-toxic, etc.
