A vehicle includes a vehicle cooling system for cooling a cabin and a battery system, each having a respective target operating range. The cooling system is configured to select among a cabin-only mode, battery-only mode, or a hybrid cooling mode for cooling the cabin and the battery system. In the hybrid mode, the system determines a desired pressure at an inlet of a compressor corresponding to a suction pressure of the compressor, to avoid cooling interruptions. The system generates a control signal based on the desired suction pressure, and applies the control signal to the compressor. Generating the control signal may include generating a feedforward signal the desired suction pressure, generating a feedback signal based on the suction pressure, or a combination thereof. For example, the use of hybrid mode based on suction pressure allows smoother response to targets with reduced delays in response in meeting the cooling demands.

The compartment further includes an upper housing arranged to accommodate said electrical equipment, and a lower housing, in which at least one fluid connection element is placed in order to supply the cooling plate with fluid, the lower and upper housing being isolated from each other in a fluidly sealed manner.

A battery assembly for an electric vehicle includes two spaced-apart longitudinal profiles extending in a length direction L, interconnected to a front and a rear transverse beam. At least three beam shaped battery modules are interconnected along their longitudinal sides via a plate-shaped interconnecting member, and extend in the length direction, to be attached to an inner surface of the front transverse beam via a bracket. Each battery module is provided with cooling channels extending in the length direction L and having an inlet situated between a transverse end face of the module and the inner surface of the front transverse beam. A water inlet duct extends from an external side the front transverse beam in a central area situated between the brackets, for connecting to a coolant inlet of the central battery module.

The present disclosure provides a multi-passage valve including a housing, a valve element, and a sealing element. The valve element is rotatably disposed inside the housing around an axis, and has at least two regions on an outer side thereof. The regions are arranged in a direction of rotation of the valve element, and each extends in an axial direction of the valve element and has a plurality of connecting passages. The sealing element extends by a distance around the valve element, keeps in contact with an outer surface of the valve element, and is provided with a plurality of openings which communicate with the outside. One of the regions is capable of being covered by the sealing element by rotating the valve element to form an operating region, each of the connecting passages in the operating region being capable of connecting at least two of the openings.

This disclosure describes at least embodiments of an aircraft monitoring system for an electric or hybrid airplane. The aircraft monitoring system can be constructed to enable the electric or hybrid aircraft to pass certification requirements relating to a safety risk analysis. The aircraft monitoring system can have different subsystems for monitoring and alerting of failures of a component, such as a battery pack, a motor controller, and/or a motors. The failures that pose a greater safety risk may be monitored and indicated by one or more subsystems without use of programmable components.
