Interessant.

Een gemiddelde semi truck (42t) heeft 110 kW driving resistance. Dus om 8h aan een stuk te kunnen rijden is ten minste 880 kWh aan batterijen nodig. Ik kan mij inbeelden dat Tesla de aerodynamica en rolweerstand verbeteren, maar laten we daar niet van uitgaan.

Een andere Californische truck bouwer, heeft al aangetoond dat Trucks op waterstof (en met 320 kWh batterij) veel economischer zijn dan klassieke Diesel Trucks : https://nikolamotor.com/one

Ben benieuwd wat Elon uit zijn hoed tovert. Trucks kunnen veel meer batterijen aan boord hebben en mogen veel meer kosten, zolang de kost/ km maar lager is dan bij klassieke diesel trucks.

Ik neem aan trucks voor korte afstanden, in het havengebieden van Los Angeles worden al E-trucks gebruikt denk ik:

Examples of Zero Emissions Technology Projects at the Port

The projects below describe the various zero emission technologies that are currently being utilized, tested, and evaluated by the Port, or are currently in the process of being developed.

Heavy-Duty Vehicles (On Road)

Transpower
Electric truck manufacturer TransPower is currently in the process of building and testing seven (7) zero emission Class 8 on-road trucks. Trucking companies have begun using the trucks to pick up containers at marine terminals and deliver them to warehouses in close proximity to the Port. These trucks will demonstrate their "ElecTruck" drive system, which integrates an on-board battery charger into the battery management system eliminating the need for an external stand-alone battery charger. The drive system is expected to provide 100 to 150 miles of range under normal operating conditions. Four of the seven trucks have been completed and deployed for demonstration, while three more are expected to begin testing in last quarter of 2015.


US Hybrid
Electric truck manufacturer U.S. Hybrid will develop and demonstrate two battery-electric trucks at the Port using the International Transtar 8600 Class 8 truck platform. The trucks will be equipped with a 300 kilowatt-hour lithium-ion battery pack to provide an estimated 100 mile all-electric operating range under fully loaded conditions. These trucks are being developed with funding provided by the US Department of Energy (see below).

Balqon
The world’s first plug-in battery-electric Class 8 truck was built in 2008 by Balqon Corporation as a demonstration project co-funded by the Port of Los Angeles and the SCAQMD. The original truck was powered by lead-acid batteries; however, with significant advances in battery technologies, the new version of the truck, Model XE-30, now operates on lithium-ion batteries which have better performance and higher energy density. The increased energy density and operational efficiencies are expected to result in an approximate 100-mile range when fully loaded. In 2012, Balqon completed a preliminary demonstration which included several round-trips from a near dock railyard to Port terminals.

U.S. Department of Energy Grants 2012 and 2014
The United States Department of Energy (DOE) awarded the SCAQMD a $4.1M grant in 2012. The grant was allocated to fund 13 zero emission truck projects from four vendors: Balqon (3), TransPower (4), US Hybrid (2), and Vision Industries (4). The funding requires a 50% contribution from vendors. Though details vary by subcontract, vendors generally have up to 1 year to produce the trucks and two years to test them. Vision Industries is no longer in business, and the remaining projects are on-going.

In 2014, the DOE awarded the SCAQMD another grant for $9.7M. The grant was allocated to fund 7 new zero emission truck projects from four vendors: TransPower (2), US Hybrid (2), BAE systems (2) and International Rectifier (1). Though project details vary by subcontract, the vendors generally have up to 1 year to produce the trucks and a 2 year testing period.
