Abstract
A controller, for a battery-operated vehicle or the like, comprises a plurality of mosfet/diode/capacitor circuits. A printed circuit board (PCB) has the mosfet/diode/capacitor circuits arranged in four sets, one set along each side of the board, and with the inner areas of the board on both sides and the outer area on at least one side being substantially solid tracking areas forming the connections to the circuits. The connectors (A, B+, B-) to circuits are located substantially along a diagonal of the board, with the connectors (A and B+) to the two sides of the diodes located at opposite corners of the inner areas of the board. The inner tracking areas are divided by isolating lines into separate fingers for the respective circuits. The mosfet and diode of each circuit are mounted on one side of the board and the capacitor on the other, with a heat sink bar located between the mosfet and diode with the mosfet and diode clamped to it by a nut and bolt passing through lugs on the mosfet and diode each a matching hole in the bar.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
