Electronic module for managing cells in heavy duty batteries, e.g traction batteries for electric vehicles

摘要

The electronic system for managing batteries formed of series connected bipolar cells has electronic circuit cards (C1, ..., C5) each associated with an individual electrochemical cell (Z1, ..., Z5). Each cell has two terminals (BP, BN) of opposite polarity. Each circuit card has a substrate (1) with holes at each end to fit over the terminals. The region round the holes is metallised to provide electrical connection to the terminals. The card carries electronic control components (4) with a printed circuit for interconnection. A data connector (6) connects via a communication cable to a central control circuit.
