Terminal tractors will be able to charge automatically, at the fastest speed possible.
Tritium, together with Stäubli Electrical Connectors, will install 33 DC fast-charging stations (175 kW each) for SSA Marine’s new fleet of electric-drive terminal tractors at the Port of Long Beach.
The key thing in the project is an automated vehicle charging system, utilizing the special Stäubli’s Quick Charging Connector (QCC) so the tractors will start charging immediately after parking next to the charger.
“The project represents the largest automated vehicle charging program at any port in the United States. Tritium’s Veefil-PK 175kW DC High Power Chargers (HPCs) will be equipped with Stäubli’s Quick Charging Connector (QCC) to enable the fast and automatic charging of all the port’s fleet of electric-drive terminal tractors, which are supplied by TransPower.”
Chargers will be installed by the end of this year, while vehicles supplied by TransPower will be delivered between late 2019 and October 2020.
“The Tritium chargers will automatically and simultaneously charge 33 terminal tractors at once, with Stäubli’s QCC enabling the automatic connection to a receptacle on each vehicle, creating a zero-touch operating environment. The QCC is touch-protected on both sides of the connector, making it possible to transmit high levels of power safely and quickly, ensuring the rapid recharge of energy storage devices. The QCC connection device offers a reliable and fully automated solution, enabling the connection of electrical vehicles for battery charging without human intervention.”
According to the press release, the project was possible thanks to a $50 million grant the Port of Long Beach obtained from the California Air Resources Board’s Zero and Near Zero-Emission Freight Facility (ZANZEFF) program.
