Abstract:
In recent years, vehicles have become increasingly electrified and individual wheel control has become
possible. This has led to an increase in demand for vehicle and powertrain testing using a hub dynamometeras a vehicle test bench. Although a hub dynamometer measures shaft torque and rotational speed and can“Toward Carbon

has developed a new 3-L GaN inverter, which has shown to improve e-motor efficiency by reducing losses
in the WLTP drive cycle by 25%. This improvement translates into less cooling demand, increased
performance, and an extended driving range. Additionally, the inverter reduces “Lautheit” by 25% andexhibits similar improvements in EMC behavior, which can be used to meet higher electric drive requirements

The cabin noise is one of the serious issues, because of vibration that occurs due to the unit being directly
installed into the suspension. Therefore, reducing the vibration is important for IWM units with considerationof the vehicle’s transmission characteristics. This paper describes countermeasures against vibration sourcesby the motor current control and against the vibration transfer through the trailing arm.

In this study, the effects of cross-coupling (CC) are investigated
for two types of circuit configurations: Independent Multi-Pad Receiver and Series Multi-Pad Receiver. As
a result, it was found that the effect of cross-coupling between the transfer coils is small for the Double-LCC
circuit, and that the effect of cross-coupling between the receiver coils is small for the circuit with SeriesMulti-Pad Receiver. Experiments also showed that the Series Multi-Pad Receiver can obtain 30% more

Abstract:
Wireless power transmission technology is attracting attention from the viewpoint of improving userconvenience during charging. Among wireless power transmission methods, the electric field coupling typehas been considered unsuitable for large power transmission compared to the magnetic field coupling type.
This time, as a result of repeated studies on the electrode and coil structure of the electric field coupling“Toward Carbon

we achieved

For many years, people talked about wireless power transfer (WPT). Since Nikola Tesla’s time in the late
1800s, wireless power transfer (WPT) has been used in applicationssuch as telemetry, satellite
communications, and radio frequency identification (RFID) tags. Most of these applications transfer low
amounts of power, in the range of microwatts to milliwatts, for data transfer. For higher- power applications,“Toward Carbon

This new design cell of the interdigitated flow channel on the GDL with porous ribs has a clear advantage
over the conventional design of interdigitated flow channel on the separator with solid ribs in being able tomaintain higher performance under conditions of both water excess and water shortage. We suggested thatthese advantages are caused by the porous ribs which contribute to proper water management in the cell, as

The model predicts the end-of-life fuel cell performancebased on the initial performance of the fuel cell and how the fuel cell system is operated, allowing thesimultaneous optimization of the hardware and software. By conducting the optimization calculation
assuming various fuel cell performances, the model derives the required fuel cell performance with the
