A medium voltage DC hybrid circuit breaker is proposed for grid protection and other related applications. Direct current braking is more challenging and complex than traditional alternating current systems that contain a zero crossing.
Electric traction systems in medium- and heavy-duty vehicles often operate inefficiently because drivetrain designs are constrained by peak performance requirements rather than typical operating conditions.
Thin film batteries currently rely on thin film electrolytes with ionic conductivities up top 3 x 10-6 S/cm. Improving the rate capability of thin film batteries requires thin film electrolytes with higher ionic conductivities.

This invention consists of bulk ionic glass films that are 01.1-50 micrometers in thickness that have intrinsic local ductility, ionic conductivity and can be processed with bulk glass processing.
This INF discloses a method to use pilot injection of methanol to maintain or improve COV of IMEP while reducing DME energy needed. The use of a methanol pilot injection allows for a reduction of DME used for ignition. It also reduces COV of IMEP.
The disclosed technology relates to a modular electric vehicle (EV) charging architecture that enables multiple vehicles to be charged dynamically and simultaneously using a shared pool of power conversion resources.
With increase in renewable energy integration into the power grid, the need for power electronic (PE) interfaces that can maximize grid support is increasing. Such interfaces are crucial to improve the grid resiliency and reliability metrics.
The smart charge management for battery life and TCO approach effectively minimizes battery degradation by considering a wide range of factors, such as ambient temperature, state of health, and battery chemistry.
This disclosure introduces an innovative tool that capitalizes on historical data concerning the carbon intensity of the grid, distinct to each electric zone.
