摘要： Methods and systems are described for enhanced engine friction generation. The enhanced engine friction generation improves the effectiveness of vehicle braking in deceleration fuel cut-off driving conditions by using engine vacuum and backpressure to temporarily increase engine pumping losses, thereby increasing powertrain drag and increasing deceleration torque to the wheels. The engine vacuum and backpressure may be created by changing the duration of the intake and/or exhaust valves. The system includes a processor and a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform operations comprising adjusting an intake valve time duration or an exhaust valve time duration to increase engine friction to enhance mechanical friction on a drivetrain of a vehicle.

摘要： Described is a new partial power converter (PPC) for the DC-DC stage of rapid-charging stations for electric vehicles (EV). The proposed converter manages only a fraction of the total power delivered from the grid to the battery, which increases the general efficiency of the system and the power density while potentially reducing the cost of the charger. The proposed topology is based on a switched capacitor between the AC terminals of a bridge converter H and does not require high-frequency isolation transformers in order to provide a source of controllable voltage between the CC link and the battery. The proposed concept can be implemented by using interposed power cells, which can improve energy quality, reduce the size of the inductor, and allow scalability for chargers of higher nominal power.

摘要： A battery management system includes monitoring devices arranged in a housing accommodating a battery. The monitoring devices monitor the battery and acquire battery monitoring information. The controller performs wireless communication with each of the monitoring devices via a wireless communication connection. The controller transmits a disconnection instruction to each of the monitoring devices. Each of the monitoring devices periodically executes a requesting operation after disconnection of the wireless communication connection. The controller accepts the requesting operation to establish the wireless communication connection. The controller and each of the monitoring devices perform a periodic communication of the battery monitoring information via the established wireless communication connection. Each of the monitoring devices determines start timing of the requesting operation based on reception timing of the disconnection instruction so that at least some of timings of requesting operations of the monitoring devices do not overlap with each other.
