Hypothetically, all vibration energy can be transformed into electrical energy; but there are certain types of vibrations that are preferred when the intent is to power a sensor or monitoring system. These vibrations need to have a steady vibration and a controlling frequency.
JAKE LINGEMAN for AutoWeek: Aim for those bumps; save the planet. Audi is working on a new suspension system called eROT (electromechanical rotary damper) that turns the kinetic energy of damper travel into usable, fuel-saving power.
“Every pothole, every bump, every curve induces kinetic energy in the car. Today’s dampers absorb this energy, which is lost in the form of heat,” said Dr. Stefan Knirsch, board member for technical development at Audi AG. “With the new electromechanical damper system in the 48-volt electrical system, we put this energy to use. It also presents us and our customers with entirely new possibilities for adjusting the suspension.”
The electromechanical dampers are arranged horizontally and feed electricity from the motion -- 100 to 150 watts on an average road during testing in Germany -- to a lithium-ion battery. A DC converter connects the 48-volt electrical subsystem to the 12-volt primary. Cont'd...
Tigo will announce the new product launch of the patented UHD-Core TS4-A (Advanced Retrofit/Add-on) Platform at SPI 2019. The new TS4-A-M (Monitoring) & TS4-A-S (Safety) units have improved lightweight hardware and lower labor costs to address a range of functions and budgets. The TS4-A-M allows module-level monitoring via Tigo's SMART Website & App. The TS4-A-S is UL-certified as a rapid shutdown solution for residential and C&I PV system. Both units join the Tigo's multivendor solution that works with almost any inverter and smart module in the global PV market.
