Abstract
A modular device having at least one master integrated circuit, and one or more slave integrated circuit modules coupled to the at least one master integrated circuit with each slave integrated circuit module of the one or more slave integrated circuit modules coupled to and associated with only a single cell of the battery. Each slave integrated circuit module of the one or more slave integrated circuit modules further comprises: detection circuitry adapted to detect data comprising one or more of the temperature, voltage or charge status, and malfunctioning of the single cell associated with and monitored by the slave integrated circuit; and an interface operable to send said detected data to the at least one master integrated circuit. The at least one master integrated circuit is adapted to send commands to a slave integrated circuit module in response to the detected data detected by the slave integrated circuit module.
