Complete solutions for wireless battery management systems by Analog Devices The wireless network protocol implemented in the wBMS system meets the automotive industry’s requirement for reliability, safety, and security under all operating conditions based on network-wide time synchronization technology.
A wireless configuration simplifies installation of a new module in the battery system. Second life – with the increasing number of vehicles, a market is emerging for ‘second life’ batteries recovered from scrapped EVs and repurposed for applications such as renewable energy storage systems and electric power tools.
This study presents a user-involved wireless battery charging approach for electric vehicles, which enables the battery to reach the user-specified state by regulating the charging current provided by a wireless charger with double-sided inductor–capacitor–capacitor compensation topology.
In this study, based upon a wireless charger with double-sided LCC compensation topology, a user-involved wireless battery charging control strategy is proposed, bringing the benefits that suitable charging current can be regulated automatically to accomplish the user demands.
In the inner loop, a fuzzy proportion–integration (PI) control algorithm is proposed to regulate the wireless charger to provide the charging current designed by the out loop. Finally, numerous real-time results are provided to verify the proposed wireless battery charging strategy.
Servicing – secure wireless capability means that the condition of the battery pack can be conveniently analysed by diagnostics equipment in an authorized garage without touching the pack. If a malfunction is detected, a faulty module can easily be removed and replaced.
