Wireless charging is an important solution to prolong the lifetime of wireless sensors with limited energy. However, charging efficiency can be greatly
The SAE J1772 charge port (right) on a vehicle can be used to accept charge with Level 1 or 2 charging equipment. The DC fast charge port (left) uses a
Using more energy efficient vehicles like hybrid and plug-in electric vehicles is an important part PHEVs and EVs have the benefit of flexible charging.
Friction and other dissipative processes convert orderly motion to disorderly motion, thwarting our efforts to achieve perfect (100%) energy efficiency in
