<p>High power inductive charging generally refers to power above 1 kilowatt. Such power is required for <a href="page.php?w=electric_vehicle">electric vehicle</a>s, and some implementations reach 300 kilowatts or higher. High-power inductive charging systems use <a href="page.php?w=resonant_inductive_coupling">resonant inductive coupling</a> for higher efficiency. These systems are usually implemented in the <a href="page.php?w=long_wave">long wave</a> range of frequencies in the tens of kilohertz, commonly 85&nbsp;kHz as the regulatory allowable</p><p>
