A battery charger and method is disclosed for detecting when a battery has a low state of health while simultaneously charging or maintaining the battery. A battery charger includes a processor; a non-transitory memory device; a power management device to receive an input power and to output a charging current; a pair of electrical conductors to electrically couple with a battery, and a display electrically coupled to the processor. The display being configured to indicate a bad battery indicator when the battery has a low state of health and whether the battery is good to start.

An electrical connector for an electric motor, includes an insulating main body with a front side configured to be coupled with the motor and a rear side configured to be coupled with a corresponding wiring harness, a plurality of electrical terminals fixed by the main body, and at least one current protection element. The at least one current protection element is positioned in the main body.

A connector includes a first connector housing, a second connector housing, and a first capacitor. The first connector housing includes a first connection terminal connected with a frame ground pattern, and a first capacitor connection part located closer to a plug housing connection part than a top face of the first connector housing. The second connector housing includes a transformer or a common mode choke coil, a second connection terminal connected with a signal ground pattern, and a second capacitor connection part located closer to the second connection terminal than the position where the transformer or the common mode choke coil is placed. The first capacitor connects the first capacitor connection part with the second capacitor connection part.

An in-line suspended power sensor coupling configuration situated within a high frequency transmission line housing that allows forward, reverse, and sampling voltage elements to all be produced simultaneously on one double sided printed circuit board (PCB). The power sensor coupling allows for calibrated coupling responses across a much wider frequency range with a single PCB assembly, as opposed to the need to cover equivalently sized frequency ranges with multiple individually fabricated coupling element assemblies.

An electrical connector carries large amounts of electrical current between two circuit boards with low resistance and low self-inductance by means of an interdigitated anode and cathode, thereby providing low dynamic voltage loss. The connector also may include, near where power will be consumed, an interposer board with on-board capacitance to provide even lower dynamic voltage loss. The connector has application to delivering low-voltage, high-current power from a power supply on a first board to electronics on a second board: the low resistance provides low voltage drop for a load current that is constant, while the low inductance and the capacitors provide low voltage fluctuation for a load current that changes. These issues are of great importance, for example, in designing high-performance computers.
