In addition, the VTA is installing a 250-500 kWh battery energy storage system, enabling the VTA Maintenance and Operations Center to function as a microgrid to power electric vehicles. With the formation of the VTA bus company's pure electric bus fleet, charging outlets along the way (on-route) will also be provided. The charging stations along the line will operate as separate microgrids powered by the energy storage system.


Momentum Dynamics' wireless charging system will be refurbished and then deployed to 10 BYD electric buses. The system's transmission efficiency from the facility to the battery is up to 94%, providing high-power charging on the road. For the transformation of the pure electric bus of VTA's fleet, the transmission energy efficiency played an important role.


This kind of in-situ charging equipment installed on the roadside enables the passenger car to complete short-term charging operation during the daily stop of the platform. It can realize multiple charging every day. It only takes five minutes to charge, and the passenger car can get enough power to complete the whole cycle. Driving.
