摘要： A circuit for discharging an energy store of a drive system includes a power electronics unit in an on-board electrical system and a single-phase DC/DC converter connected upstream of the drive system. The converter includes a first capacitor, a coil connected downstream of the first capacitor, a first switch, a second switch connected downstream of the coil, and a second capacitor connected downstream of the second switch. The first switch is for a first current circuit including the first capacitor and the coil, and the second switch is for a second current circuit including the first capacitor, the second capacitor, and the coil. During a discharge process, the first switch and the second switch are designed to be switched in an alternating manner and differently relative to each other such that either the first current circuit or the second current circuit is closed to actively discharge the energy store.

摘要： A starter battery system for an air cooled engine rated at less than 50 horsepower. The system includes four lithium iron phosphate cells and a charging circuit configured to be powered by rotation of an air cooled engine. A voltage developed by the charging circuit is applied to the four lithium iron phosphate cells without battery management circuitry provided between the charging circuitry and the four lithium iron phosphate cells.
An engine which includes at least one piston, a rotatable crankshaft coupled to the at least one piston, a starter motor configured to selectively initiate rotation of the crankshaft, a lithium-ion battery in electrical communication with the starter motor, the lithium-ion battery having at least one cell, and a charging system configured to be powered by motion of at least one component of the engine. The charging system is configured to continuously apply a voltage potential to the at least one cell while the engine is in a running condition.

摘要： A battery management system includes a monitoring device and a control device. The control device transmits request data requesting transmission of battery information, and the monitoring device transmits response data including the battery information to the control device. The control device makes next request data include communication establishment information and transmits the next request data. The monitoring device includes a transmission buffer capable of individually accumulating the battery information for multiple times. The monitoring device deletes the battery information corresponding to communication establishment from the transmission buffer, and holds the battery information corresponding to communication failure in the transmission buffer based on the communication establishment information.

摘要： A method of operating a battery system for providing electric energy to a vehicle. Sensor signals representing physical quantities of individual cells and/or individual modules of at least one battery of the battery system are generated. The sensor signals are transferred to a first and a second system controller. Both the first and second system controller evaluates the sensor signals and controls the battery system, depending on corresponding evaluation results. The first system controller is operated in combination with a first monitoring device and the second system controller is operated in combination with a second monitoring device. The first monitoring device monitors an operation of the second system controller and the second monitoring device monitors an operation of the first system controller. Depending on monitoring results of the first monitoring device and of the second monitoring device, the battery system is controlled.
