Systems and methods for charging an electric bus having a charging interface on its roof may include determining that an approaching bus is supposed to be charged at the charging station, lowering the charging head of the charging station to land on the roof of the bus, and moving the bus with the charge head on its roof to engage the charging head with the charging interface.

A device for charging a battery, or a battery of an electric traction automotive vehicle, based on a three-phase or single-phase power supply network, including a filtering stage including a capacitive assembly and configured to be connected to the power supply network. The device includes a mechanism to monitor capacitive assembly and to detect a deviation in value of the capacitance of at least one capacitor of the capacitive assembly on the basis of voltages and currents measured across the input terminals of the filtering stage.

A method for sensorless control of a separately excited synchronous machine having a rotor includes the following steps: feeding a test signal on a parameter of an electrical current driving the rotor; measuring the parameter of the electrical current driving the rotor on an axis of the coordinate system describing the synchronous machine; determining an error signal by correlating the measured parameter of the electrical current driving the rotor with a temporally delayed test signal which is determined from the fed test signal; and adjusting a rotor angle as a reaction to the error signal if the error signal has a value not equal to zero.

An example system can include a base station providing electrical power, a charging interface configured to couple with a charging port of a vehicle and a cradle of the base station, a controller associated with at least one of the base station, the charging interface, or combinations thereof, the controller configured to execute a docking ruleset to determine when a docking failure occurs between the charging interface and the cradle of the base station and execute a remediating action in response to the docking failure.

A vehicle driving device includes an inverter which drives a motor. The inverter includes: a three-phase bridge circuit including a plurality of switching elements; a three-phase short circuit which short-circuits three phases of the motor via the three-phase bridge circuit; and a control circuit. The control circuit includes: a microprocessor which drives the three-phase bridge circuit; a malfunction notification circuit which outputs a malfunction notification signal when the microprocessor is malfunctioning; and a latch circuit which holds the malfunction notification signal outputted from the malfunction notification circuit. The control circuit outputs a three-phase short-circuit drive signal which drives the three-phase short circuit, based on the malfunction notification signal held by the latch circuit.

An object of the present invention is to provide a technique capable of predicting whether a vehicle can reach a desired facility or point by traveling on a retrieved route to the destination. A navigation apparatus includes an information storage that stores map information, a current position detector that detects a current position of the vehicle, an instruction receiver that receives a setting of a destination, and a vehicle information receiver that receives information on a remaining amount of the electricity charged. The navigation apparatus further includes a processing circuitry that retrieves a route to the destination from the map information and calculates a first travelable range in which the vehicle is allowed to travel from the current position through at least a part of the route to cause the first travelable range to be displayed.

A method according to an exemplary aspect of the present disclosure includes, among other things, activating hazard lights of an electrified vehicle in response to a high voltage battery disconnect event.

A method for checking a model temperature of an electrical machine ascertained by a temperature model. At least one manipulated variable relating to the electrical machine is specified by a regulation of the electrical machine as a function of a setpoint variable. A model value of the manipulated variable is ascertained as a function of the manipulated variable and the model temperature from a machine model comprising at least one temperature-dependent parameter. A difference between the actual manipulated variable of the regulation and the model value of the manipulated variable and/or a difference between a variable derived from the actual manipulated variable of the regulation and a corresponding further variable derived from the model value of the manipulated variable is ascertained. The difference is compared to a limiting value and, if the limiting value is exceeded, a deviation of the model temperature from an actual temperature of the electrical machine is detected.

Working equipment including a hydraulically movable arm arrangement for a crane, an electric motor, a hydraulic pump, and a pump controller. An equipment controller is arranged to determine a maximum flow limit from the pump in dependence of a comparison of a current limit received from a battery system and a current consumption monitored by the pump controller, and to compare the determined limit with required flow of hydraulic fluid from the pump needed to move the movable arm arrangement in accordance with operating signals, and if the result does not fulfil a rule of a set of fluid control rules, the controller adapts the operating signals to reduce flow of hydraulic fluid to at least one of a plurality of actuators according to a rule of a set of adaptation rules, such that at least one rule of the set of fluid control rules is fulfilled.
