The present disclosure relates to the field of vehicle technology and provides an energy recovery control method, a system, and a vehicle. The method is applied in a vehicle, and the vehicle comprises a drive motor and a battery electrically connected to the drive motor; a first energy recovery torque curve with respect to the drive motor is pre-configured in the vehicle, and the first energy recovery torque curve is used to indicate a correspondence relationship between vehicle speed and energy recovery torque of the drive motor. The present disclosure performs reduction on a first energy recovery torque curve by means of utilizing a reduction ratio, allowing energy recovery in accordance with a relatively low torque strength when a usable charge power of the battery is unable to satisfy a preset power requirement corresponding to the first energy recovery torque curve.

The invention relates to a feedback current control device and aerial equipment. The feedback current control device includes: a feedback current capture module, located on a current capture circuit and configured to capture a feedback current; a first switch module, configured to turn on or off the current capture circuit; and a control module, including: a first receiving unit, configured to receive a first voltage at one end of the driver and a second voltage at one end of a battery on a feed circuit and a temperature of the battery; and a first control unit, configured to control the first switch module to turn on the current capture circuit for capturing the feedback current when the difference between the first voltage and the second voltage is greater than a preset voltage and the temperature of the battery is less than or equal to a preset temperature.

An energy and supply system includes a switching device, a battery detection device, a speed detection device, a processing device, a main storage battery and a backup storage battery. Using the speed detection device, the processing device determines whether the driving speed of the vehicle exceeds a preset speed threshold, or it determines whether the rotation speed of the engine exceeds a preset rotation speed. The processing device uses the battery detection device to determine whether the main battery capacity is greater than the preset capacity. If the processing device determines that the driving speed of the vehicle exceeds a preset speed threshold, or it determines that the rotation speed of the engine exceeds a preset rotation speed, and it determines that the main battery capacity is greater than the preset capacity, the processing device controls the switching device.

Systems and methods for charging electric vehicles and for quantitative and qualitative load balancing of electrical demand are provided.

A battery charging device includes a conversion part that converts an alternating current output from an alternating-current generator into a direct current by a switching element and supplies the direct current to a battery; a number-of-revolutions acquisition part that acquires a number of revolutions of the alternating-current generator based on a signal responsive to the operation of the alternating-current generator; and an output control part that determines an energization phase angle that defines a timing of energization of the switching element of the conversion part for supplying a charging current from the alternating-current generator to the battery, and controls energization of the switching element based on the energization phase angle.

A vehicle includes a vehicle battery; a vehicle sensor configured to detect a current, a voltage and a temperature of the vehicle battery; and an alternator configured to output a target voltage to the vehicle battery. A controller is configured to calculate state of charge (SOC) estimation based on the current, voltage and temperature of the vehicle battery, calculate an initial SOC based on a direct current internal resistance (DCIR) map and apply the initial SOC to the SOC estimation, when an open circuit voltage (OCV) is maintained in a predetermined range after engine-off, and adjust an available SOC range based on a difference between an actual battery charge current amount, to which the initial SOC is applied, and the calculated SOC estimation.

The disclosure is directed to methods and systems for provisioning mobile electric vehicles with various operational settings data transmitted over the air. A vehicle or its components may operate according to operational settings corresponding to operational settings data included in the vehicle components. A server that is remote to the vehicle may comprise operational settings data and may transmit operational settings data to the vehicle. The server may transmit operational settings data automatically, such as on a periodic basis, in response to a request, such as from a user or from a vehicle component or anytime new or updated operational settings data are available for the vehicle or its components.

A power supply system includes: a voltage converter that converts a voltage between first and second power circuits; a power controller that controls charging and discharging of first and second batteries; a cooling output controller that controls cooling output for the second battery; a temperature remaining-capacity acquirer that acquires a temperature remaining-capacity T2_mar; and a cooling remaining-capacity acquirer that acquires a cooling remaining-capacity PC2_mar depending on a difference between maximum cooling output and the cooling output of the second cooler. The power controller is configured to stop the voltage converter in a case where at least one of the temperature remaining-capacity T2_mar and the cooling remaining-capacity PC2_mar is less than an associated one of a threshold value for the temperature remaining-capacity and a threshold value for the cooling remaining-capacity and a potential difference between the first and second batteries is equal to or more than a potential difference threshold value.
