Controlled Power Technologies shows 48V electric supercharger

The 16th Annual Supercharging conference was held last week at the Technical University of Dresden in Germany where many interesting new developments in the critically important field of forced induction were shown. Most motor vehicles only use maximum power for a small fraction of their time on the road, and with downsizing of engines now standard practice for the auto industry, supercharging is an ideal way of providing that power boost from a small engine. We've written previously about Controlled Power Technologies' (CPT) 12 volt electric supercharger, but it now has a 48 volt version which uses 7 kW of electrical power and delivers (an extra) six to ten times that power at the crankshaft for overtaking and steep hills.  Read More

CPT's auto exhaust gas energy recovery system

A lot of energy has traditionally been flushed down the exhaust pipe of the internal combustion engine and it's interesting to see that a number of companies, most notably BMW and Toyota until now, have been working on harvesting that power thanks to the imperatives of the energy crisis. Now Controlled Power Technologies (CPT), best known for its VTES electric supercharger, is working on exhaust gas energy recovery too. CPT estimates it will take five years to bring its research to market.  Read More

Electrically supercharged gasoline engine achieves diesel levels of CO2

We have previously written about the potential of UK-based Controlled Power Technologies' (CPT) electrically driven supercharger and that potential came closer to realization this week when CPT and the world’s largest independent developer of vehicle powertrains, AVL List GmbH (AVL), unvelied a jointly developed gasoline engine that retains all the strengths, develops more power and at the same time reduces CO2 levels to that of an equivalent diesel powertrain.  Read More

Electric supercharger promises instant power boost

Now here’s an idea that begs the question as to why someone hasn't thought of it before. Controlled Power Technologies (CPT) has come up with a clever technical solution for the problem of ‘downsizing’ engines without compromising driveability and performance – the electrical supercharger. The company’s low-cost, production-ready, Variable Torque Enhancement System (VTES) employs an electrically-driven supercharger to significantly improve low speed torque response for naturally-aspirated or turbocharged gasoline and diesel engines. Unlike traditional mechanically-driven superchargers and exhaust-driven turbochargers, it doesn't suck power all the time because it is only engaged when needed, and delivers an immediate boost within 350 milliseconds. Most significantly, CPT claims the VTES can be implemented on current vehicles, using existing 12 volt electrical architecture, and when used in series with a turbocharger, the 2kW of electrical power translates into 20kW at the crankshaft.  Read More
