The tray includes a bottom plate and a plurality of side beams and forms a receiving space for accommodating a battery unit. The receiving space is open at one side. The cover plate is configured to close the open side of the receiving space. The plurality of side beams include two first side beams opposite to each other. The middle beam is in the receiving space and two ends of the middle beam along a length direction are respectively spaced by a predetermined distance from or in contact with the two first side beams.

A drive unit includes an internal combustion engine (21) disposed in an engine compartment (10), a first electric motor (31) and a second electric motor (33), and an inverter (27) disposed above an electromotive unit (23). The drive unit has: a first harness (41) that connects the inverter and the first electric motor; a second harness (42) that connects the inverter and the second electric motor; a step portion (51) formed so as to be recessed on one side or the other side, in the left-right direction, of the upper end of the inverter; and an AC terminal block (55) disposed in the step portion. The first harness and the second harness respectively extend downward from the DC terminal block while extending outward, and are respectively connected to upper parts of the first electric motor and the second electric motor.

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetically induced force that introduces a force threshold that, in effect, provides a threshold to part movement and confers a degree of hysteresis, preventing movement until a sufficiently large energizing force is applied. The effect may be further altered by use of an additional magnetically induced force interaction with at least one further member to urge or slow movement once started and/or to prevent movement once a new position is reached.

An electric vehicle charging station is provided. The electric vehicle charging station is configured to safely disconnect power during an impact. The electric vehicle charging station includes a mechanical break-away coupling connecting a base section and a charger section, the mechanical break-away coupling including a failure point to allow the charger section to break away from the base section. The electric vehicle charging station also includes an electrical break-away coupling connecting at least one wire extending from the base section to the charger section, the electrical break-away coupling configured to disconnect the at least one wire from the charger section when the charger section breaks away from the base section. A pedestal for an electric vehicle charging station is also provided.

Discharge systems for electric vehicles and electric vehicles having discharge systems. In one implementation, a discharge system for an electric vehicle includes a step-down power converter configured to step down an input voltage to an output voltage; discharge circuitry coupled to the output of the step-down power converter, wherein the discharge circuitry is reversibly driveable to load the step-down power converter; an input component configured to receive input that originated from a human user or a sensor of the electric vehicle, wherein the input indicates that the electric vehicle is to shutdown; and discharge drive circuitry configured to drive the discharge circuitry to load the step-down power converter in response to the indication that the electric vehicle is to shutdown.
