摘要： An automatic battery fluid level monitoring system is provided. The automatic monitoring system includes a fluid consumption algorithm, programmed into a microprocessor based motor controller, connected through a communications link to a microprocessor based battery charger. The battery charger is electrically connected to a flooded type battery as well as a power connection such as being plugged into an outlet, the electrical connection from an alternator, or the like. Once the fluid consumption algorithm indicates that the fluid level is too low, a battery fluid indicator is activated utilizing a visual and/or audio display. After the battery is refilled, a fluid added reset is triggered, which deactivates the battery fluid indicator. Additional embodiments include utilizing a wired or wireless connection to a remote fleet management system, as well as alternative vehicle performance rules wherein the vehicle performance parameters can be purposefully altered to effect the ongoing performance of the vehicle.

摘要： The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During operation, the system uses a reference electrode in the battery to monitor an anode potential of an anode in the battery during charging of the battery in the portable electronic device. If the anode potential falls below an anode potential threshold, the system modifies a charging technique for the battery to extend a cycle life of the battery. For example, the system may reduce a charge current of the battery if the anode potential falls below the anode potential threshold to prevent degradation caused by a negative anode potential during charging of the battery.

摘要： An apparatus for detecting the state of a checkable storage battery in a vehicle having at least two vehicle onboard power supply systems of different operating voltages is provided. The vehicle onboard power supply systems are coupled by a DC/DC converter, which converts a first DC voltage of a first vehicle onboard power supply system into a second DC voltage of the storage battery in the second vehicle onboard power supply system. The vehicle onboard power supply systems have a control device that includes a test signal module configured to supply a test signal via the DC/DC converter to the checkable storage battery, a measured value detection module configured to measure the reaction values of the checkable storage battery, and an evaluation module configured to detect the state of the storage battery from the measured reaction values.
