摘要： Communication between an information handling system and battery has improved reliability by repeated communications of information from the battery using different commands from the information handling system. A battery management unit responds to a first command from an information handling system by sending information stored at a first address associated with the command and then saving the first address at second address. A power manager of the information handling system sends a second command having the second address to the battery management unit. The battery management unit responds to the second command by retrieving the first address stored at the second address, retrieving information stored at the first address and sending the information to the power manager. The power manager restricts operations of the battery, such as charges or discharges, unless the information received in response to the first and second commands matches.

摘要： A battery system may be provided with a battery charge current path that is different from the battery discharge current path of the battery system, for example, by providing no controlled charge circuitry (e.g., providing no C-FETs) in the discharge current path of the battery system to avoid the power loss experienced across the C-FETs of a conventional battery system during battery system discharging operations.

摘要： A method and associated system are disclosed for verifying charging failures for smart batteries by measuring input charging voltage and associated systems. In one embodiment, a determination is made whether or not a charging current is indicative of a battery failure by utilizing an analog-to-digital (A/D) port to measure the input charging voltage. As long as the measured input charging voltage is below the cell pack voltage or some set voltage value, whichever is higher, the BMU considers a charging current detection to be a false failure indication. If the measured charging voltage is above the cell pack voltage and the set voltage value, the BMU considers the charging current detection to be a positive failure indication. The BMU can then disable the battery or implement other verification steps before disabling the battery, as desired.

摘要： Plural batteries installed in an information handling system are simultaneously charged in a constant current mode to a predetermined charge and then in a constant voltage mode to a full charge to provide a reduced charge time and improved battery life. A current regulator integrated in a battery casing monitors current applied at the battery to maintain constant voltage charging. Voltage to ground of the other batteries is monitored to adjust current at those batteries where voltages in all of the battery cells are maintained substantially equal during charging.

摘要： A system for dynamic discharging to detected derated battery cells. In such a system, a battery cell capacity, cell voltage, as well as a time to discharge are used in combination to identify good or bad battery cells. More specifically, during a dynamic discharge cycle, an accumulated discharge capacity value is calculated and monitored by a charge level battery gas gauge via analog to digital (A/D) converters and an internal discharge time value is monitored. One of the values is assigned as a fixed value and the other value is used to identify good or bad batter cells.
