In recent years, automobile development has become complicated due to electrification and advanced technology, so it is an efficient verification is required. This paper focuses on the HILS verification of xEV development and introduces the establishment of a real-time verification method applying causal models, along with the efficiency of verification in the MBD process, illustrated with specific examples.

Technology for optimizing pump startup in electric vehicle cooling systems

In recent HEVs and EVs, multiple components are integrated to achieve weight reduction and cost savings. However, there is a risk of unintended rotation of the electric pump during cooling circuit switching, which can lead to startup failures. This study examines whether incorporating position-fixing logic into an externally rotated electric pump can enable rapid and proper startup.

As an effort to reduce the cost and weight of electric vehicles, we have been studying the eAxle, which integrates a power converter for charging into the motor and inverter. In this paper, we present the results of our study and actual device verification of an eAxle with an integrated charging function to improve performance during motor drive and DC quick charging.

Using a capacitive coupling method, which has a simple structure and prevents metal foreign objects from inducing heating, we demonstrated that it is possible to provide a stable power supply of several hundred watts per AGV from a single RF power source to multiple AGVs traveling within a 10-meter power supply section.
