摘要： Charging control techniques for a vehicle including an engine that drives an alternator configured to charge a battery of the vehicle comprise modeling a fuel consumption of the alternator for each load level across a range of alternator loads using an engine torque model and a set of operating parameters of the engine, determining an energy output from the alternator for each load level across the range of alternator loads, calculating a cost-to-charge metric based on the modeled alternator fuel consumption and the determined alternator energy output for each duty cycle across a range of duty cycles of the alternator, determining an optimal cost-to-charge from the calculated cost-to-charge metrics, determining a target cost-to-charge metric based on a state of charge of the battery, and operating the alternator accordingly at an optimal duty cycle based on the metrics and current engine operating conditions.

摘要： An electric switch, in particular for an electric tool with an electric motor. The switch has first electrical terminals for electrical connection to a voltage supply and second electrical terminals for electrical connection to the electric motor. The switch has an actuating mechanism which can be adjusted between an initial position and a final position, wherein the electric motor is switched off when the actuating mechanism is located in the initial position and is switched on when the actuating mechanism is not located in the initial position. The switch also has a braking circuit for braking the electric motor, the braking circuit operating when the actuating mechanism is reset to the initial position. The switch also has a reversal circuit for switching over the direction of rotation of the electric motor. The braking circuit is arranged between the second electrical terminals and the reversal circuit.

摘要： A linkage system for loading machines is mounted on two lift-arms (14) supporting a pallet-lifting fork or a bucket (22) at the ends of the lift-arms. The linkage system is so designed that when using a bucket (22) or pallet-lifting fork the linkage system will ensure that the bucket or lifting fork will take a substantially desired angular position as it is raised and lowered, without needing to make adjustments to the tilt-cylinder as the bucket or lifting fork is raised.
