Electric Vehicle Powertrain Systems Engineering for Performance and the Challenges When Comparing to ICE Powertrain Performance

admin    Drive Subsystems ESS (battery subsystems) Feature Powertrain
Why do electric powertrains not perform like ICE (internal combustion engine) powered ones in track situations?  (however for drag racing, high performance electric vehicles do just fine).  What’s this “throttling” all about?   Fielding questions like this, there seems to be continual “puzzlement” in comparing power obtainable from Electric (BEV –...

Multi-speed gearboxes can offer many benefits for EV powertrains depending on application

admin    Drive Subsystems Energy Efficiency Feature Powertrain
Electric motors have full torque at 0 rpm and a much wider operating RPM range than ICEs (internal combustion engines).  Despite this feature, the efficiency of electric motors still varies at different speeds – they operate at a peak efficiency of around 90-95% but this can fall to 60-70%, particularly...

When Looking for Electric Powertrain Parts, Purchase From those Who Actually Use What they Sell

admin    Feature Powertrain
We believe that those companies and individuals interested in doing their own electric vehicle conversions and engineering for new powertrains, should consider lowering your project risk, purchase parts and subsystems from  a source that uses what it sells, like QuantumWorks and its partners – we actually use the parts and sub-systems in our...

Toyota admits ‘Elon Musk is right’ about fuel cell, but moves forward with hydrogen anyway

admin    Feature Powertrain REXs (range extenders)
Toyota now admits that Tesla CEO Elon Musk, who called hydrogen fuel cell “incredibly dumb”, “is right,” but the company is still heavily investing in the technology. For years, Toyota has been betting on hydrogen fuel cell over battery-electric vehicles for its zero-emission vehicle strategy. It put the Japanese automaker...
