Systems and methods are disclosed herein for automatically planning the workday of a battery unit powered electric work vehicle. The vehicle includes a chassis supported by traveling devices, itself further supporting a work implement. A battery unit discharges energy for at least assisting with actuation of the traveling devices and/or work implement. A controller receives input data from a user regarding specified missions to be performed by the work vehicle in a given period of time, and predicts rates of energy consumption for at least one operating mode corresponding to each remaining mission to be performed. The controller further generates, to a user interface, output data corresponding to a required charge state of the battery unit based on the predicted rates of energy consumption, relative to a detected current charge state of the battery unit. The controller may monitor activity and/or consumption rates throughout the day and proactively generate outputs for, e.g., usage optimization.

Methods and systems are provided for enabling vehicle speed control without overfilling a system battery. In one example, braking energy is applied (or recuperated) by applying a negative torque from BISG until a system battery has been sufficiently charged. Thereafter, the electrical power generated by the BISG is used to operate an electric boost assist motor, and the energy is recuperated in the form of stored compressed air.

A hybrid power drive system, including a power battery device, a range extender system, and a motor drive system. The power battery device is configured to supply power to the motor drive system. The range extender system includes an engine and a generator. The generator is able to generate power under the driving of the engine to supply the power to the motor drive system and/or charge the power battery device. The hybrid power drive system further includes a vehicle control unit configured to control the engine and/or generator of the range extender system to generate a driving force. The range extender system is mechanically connected to a main coupling mechanism to transmit the generated driving force to a main drive axle of a vehicle by means of the main coupling mechanism to drive wheels on both sides of the axle to rotate. Also provided is a vehicle having the hybrid power drive system. According to the hybrid power drive system and the vehicle having same, the vehicle control unit is utilized to control the engine and/or generator of the range extender system to generate the driving force for different application operating conditions, and thus the economy of the vehicle can be effectively improved.

A vehicle that operates in an autonomous driving mode and includes: an occupant sensing unit that is configured to sense an occupant inside the vehicle; and at least one processor configured to: determine, through the occupant sensing unit, whether the vehicle is occupied; and in a state in which the vehicle operates in the autonomous driving mode, control one or more in-vehicle devices based on a determination of whether the vehicle is occupied.

In an aggregation system comprising a control apparatus which is provided for each consumer and a server apparatus, the server apparatus calculates, for each of the consumers and as an allocation amount of the consumer, an upper limit value for the power which the consumer inputs from the system or a lower limit value for the power which the consumer is to output to the system, according to a requested power provision amount, and sends the respective control instructions designating the calculated allocation amount of each consumer to the control apparatus of the consumer, and the control apparatuses each control the charging and discharging of the corresponding power apparatus so that the power input from the system is equal to or smaller than the allocation amount designated in the control instruction or so that power equal to or larger than the allocation amount is output to the system.

An energy storage and regeneration system that converts irregular, non-constant, and variable input power to regular, constant, and controlled output power using hydraulics whereby the irregular input power is used to pump hydraulic fluid into an accumulator array where it is stored pressurized. Energy is released in a controlled fashion using a hydraulic motor operated by the pressurized hydraulic fluid from the accumulator array, in accordance with the specified power demand. One or more power units may be deployed depending on the amount of energy required at the output. Each power unit includes a hydraulic motor and associated floating accumulator whose internal pressure is controlled to maintain a substantially constant pressure differential across its associated motor. The system can be integrated into various energy system sources including renewable energy such as wind, PV or thermal solar, wave, tidal, etc. as well as various types of vehicles such as cars, trucks, motorcycles, trains, boats, etc.

The flywheel comprises a hub and an annular part, the shaft is disposed through the annular part, the annular part is fixed to the shaft via the hub, and the annular part has at least one cavity. The electric motor assembly is accommodated in the cavity and comprises a first motor rotor and a motor stator. In the cavity, the first motor rotor is fixed on the shaft, and the motor stator is fixed to the casing and located between the first motor rotor and the annular part.
