Abstract: Disclosed is a crash handling system for an aircraft, comprising an altitude surveillance system adapted to receive altitude data from an altitude sensor and issue an altitude warning signal when a predetermined altitude condition is fulfilled, a crash detection unit, comprising an acceleration detector and issues a crash detection signal when a predetermined acceleration condition is fulfilled, a control unit operatively coupled to the altitude surveillance system and the crash detection unit to receive respective altitude warning signals and crash detection signals; and an energy storage system isolation means operatively coupled to the control unit to electrically isolate an energy storage system of the aircraft upon reception of an activation signal, wherein the control unit transitions from a disabled operation state to an enabled operation state when the altitude warning signal is received; and to issue the activation signal upon reception of the crash detection signal when in enabled state.

Abstract: Disclosed is a battery assembly, comprising a battery box, comprising a housing including a base plate and a cover; at least one battery cell stack mounted inside the housing, wherein each battery cell stack comprises a plurality of battery cells stacked on top of the base plate along a stacking direction and electrically connected in series or in parallel; electrical connectors disposed on the outer side of the housing; and an interface unit for coupling with an electronics unit; and an electronics unit, comprising electronic control components; and an interface unit for coupling with the battery box; wherein in use the battery box and the electronics unit are interfaced by their such respective interface units such that operation of the at least one battery cell stack is controlled by the electronic control components of the electronics unit. Furthermore, the invention relates to an electrical propulsion VTOL aircraft comprising such a battery assembly.

Abstract: The present disclosure relates to a battery management system for an electric air vehicle such as an eVTOL aircraft for observing a battery system state and a battery health state of an energy storage system of the air vehicle. Based on an observation result, a state prediction, in particular, a prediction of the remaining accessible energy, is carried out during a flight. In particular, the observation and prediction is performed by two independent and dissimilar lanes of the battery management system. A first lane predicts the battery state according to a pre-defined flight profile representing a worst case scenario. A second lane predicts the battery state according to a planned flight profile so as to determine a range of the flight. Hence, it can be confirmed during the flight that the intended destination can be safely reached with the remaining accessible energy.

Abstract: A solid state relay structure for use with different alternating current motors having a range of full load current and service factor ratings. The relay includes a rectangular housing and bores extending through the housing through which conductors to the motor are passed. The rear end of the housing is spaced from the panel on which the relay is mounted so the conductors may be looped through the bores when portions of the looped conductors are passed in the space between the rear end of the relay and the panel. The solid state components of the relay are encapsulated in the interior of the housing and are connected to switches, terminals, and a light emitting diode located at the front of the housing so the relay may be easily programmed for use with motors having different ratings. The terminals and operating and test instructions, located at the front end of the relay, provide a convenient arrangement for wiring the relay in its control circuit and information to program the relay.
