摘要： An embodiment relates to a method for predicting a voltage dip in a vehicle electrical system before a planned start of a load in a motor vehicle. The embodiment operates to ascertain a value of supply current expected to be required after the start of the load. An electrical voltage source and an energy store connected in parallel to a voltage source via the vehicle electrical system provide the supply current for operating the load. The energy store blocks a charge current into the energy store or blocks a discharge current out of the energy store based on a vehicle electrical system voltage of the vehicle electrical system being greater than a maximum value. Based on an instantaneous value of the vehicle electrical system voltage, the embodiment further ascertains a proportion of the supply current that the voltage source generates as a source current without the energy store until the vehicle electrical system voltage has fallen to the maximum value.

摘要： A multi-source energy storage system, it includes a first energy storage system, a second energy storage system, and a second DC/DC converter and controller and a method for supplying power to an electrical load from multiple energy storage systems. The first energy storage system can be coupled to an electrical load. The second DC/DC converter and controller can be coupled between at least one of the following: a second energy storage system and a first energy storage system or electrical load. The controller settings control the first and second energy storage systems and the second DC/DC converter runs in both precharge mode and normal mode. In the precharge mode, the first energy storage system charges the second energy storage system via the second DC/DC converter. In normal mode, the second energy storage is coupled to the electrical load via the second DC/DC converter.

摘要： A power delivery system for an electric vehicle provides efficient power management for either continuous or intermittent high-performance operation, using a boost stage and an on-board charging circuit. A main battery, configured as a high-capacity power source, supplies power to the electric motor under normal load conditions. An auxiliary boost battery assists the main battery in supplying a high-level current at a higher discharge rate thereby causing the motor to operate in a high-performance drive mode. A charging circuit recharges the boost battery from the main battery during operation of the motor. The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries. In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load. In another embodiment, power management can be based on timed intervals.

摘要： A vehicle includes an energy storage, a motor driver, an electric motor, and circuitry. The motor driver is configured to convert direct-current power to alternating-current power and to convert alternating-current power to direct-current power. The electric motor is connected to the energy storage via the motor driver to move the vehicle. The circuitry is configured to drive the electric motor with a first current value to consume excess electric power. The first current value is different from a minimum current value to generate regeneration power arising from a braking force. The circuitry is configured to drive the electric motor with a second current value smaller than the first current value if a temperature of the electric motor is higher than a first threshold temperature or a temperature of the motor driver is higher than a second threshold temperature.
