Abstract: A charging pad for an electric vehicle includes a coolant assembly, a magnetics assembly, and an electronics assembly. The coolant assembly has a top wall and a bottom wall which form a coolant channel for circulating coolant through the coolant assembly. The magnetics assembly is configured to wirelessly receive power from a charging source induction coil arrangement facing the magnetics assembly. The magnetics assembly is adjacent the bottom wall of for heat generated by the magnetics assembly to thermally conduct from the bottom wall into coolant in the coolant channel. The electronics assembly is configured to convert the power wirelessly received by the magnetics assembly into electrical power for charging the electric vehicle. The electronics assembly is arranged adjacent the top wall for heat generated by the electronics assembly to thermally conduct from the top wall into coolant in the coolant channel.

Abstract: An induction coil is described for wireless charging of a vehicle battery. The induction coil includes a first electrically conductive strip, a second electrically conductive strip, and a first electrically insulative strip between the first and second electrically conductive strips. The first electrically insulative strip electrically isolates the first electrically conductive strip from the second electrically conductive strip. The first electrically conductive strip, the first electrically insulative strip, and the second electrically conductive strip are integrated into stack, where the stack is configured as multiple windings. The first and second electrically conductive strips are adapted to conduct an alternating current. Alternating current flow through the first and second electrically conductive strips and the plurality of windings generates a magnetic field for wireless inductive charging of the vehicle battery.

Abstract: A bus bar for use in conducting an alternating current may comprise multiple substantially parallel ribs and an electrically conductive attachment feature. Each rib may include a first and second end. Each rib may be provided for conducting a substantially equal portion of the current. The ribs may be spaced apart to provide gaps therebetween for airflow through the gaps. The electrically conductive attachment feature may connect the first ends of the plurality of ribs, and may be provided for attaching the plurality of ribs to an electrical component. An electrically insulating spacer may be located between at least two of the ribs, contacting and providing physical support to those ribs.

Abstract: An electric current sensor for detecting a leakage current from an electric vehicle charger. The current sensor includes a magnetic core having a gap formed therein, a first conductor wound around the magnetic core to form a first coil, a second conductor wound around the magnetic core to form a second coil, and a tunnel-magnetoresistance (TMR) sensor element arranged in the gap of the magnetic core. A difference between electric current flow in the first and second conductors produces a magnetic field in the gap of the magnetic core proportional to a leakage current, and the magnetic field produces a voltage in the TMR sensor element indicative of a value of the leakage current.
