A system for restricting power to a load to prevent engaging circuit protection device for an aircraft. The system includes an energy source of an aircraft. The system further includes a plurality of sensors configured to sense at least an electrical parameter of a load of the plurality of loads. The system further includes an aircraft controller configured to receive electrical parameter of a load of the plurality of loads from the plurality of sensors, compare the electrical parameter to at least a current allocation threshold, detect that the electrical parameter has reached the current allocation threshold, calculate a power reduction to the load, and reduce power from the at least an energy source to each load of the plurality of loads by the power reduction. The system further includes at least an electrical circuit of an aircraft, wherein the electrical circuit comprises a circuit protection device.

A vehicle traction device having at least one energy storage component; at least one traction component; at least one acceleration sensor including a pressure sensor, a motion sensor, a gyroscopic sensor, an accelerometer, and/or a piezoelectric sensor; and at least one deceleration sensor including a pressure sensor, a motion sensor, a gyroscopic sensor, an accelerometer, and/or a piezoelectric sensor. The at least one acceleration/deceleration sensor is responsive to an operator input, and when the operator input is applied to the at least one acceleration/deceleration sensor, the energy traction device is signaled to transfer energy from the at least one energy storage component to the forward propulsion of the vehicle, or vice versa, using the at least one traction component. The vehicle traction device may be incorporated into, for example, a wheel, a motor, and/or a transmission.

A method of two-step variable valve lift (VVL) operation learning control for a vehicle may include: applying, by a lift controller, a VVL control to an electric two-step VVL system; determining, by the lift controller, whether the vehicle is running in an electric vehicle (EV) mode; and when the vehicle is running in the EV mode, performing, by the lift controller, a learning time securing control of allowing a VVL operation learning to be performed by engine operating for an operation avoidance area and an operation avoidance time which are applied to a secondary lift of an exhaust valve.

A fault tolerant voltage measurement method for battery management systems is proposed for reliable and prompt cell fault and sensor fault detection. The key of the method is that it correlates one voltage sensor reading with multiple cell voltages and vice versa. When a cell fault occurs, fault readings will be revealed by multiple voltage sensor readings. Similarly, when a sensor fault occurs, multiple cell voltages will be influenced. Compared with the traditional one-to-one correspondence voltage measurement, the proposed method increases the credibility of sensor/cell fault decisions. Furthermore, it does not increase the hardware cost, and is easy to be adopted in real applications.
