The first two e-Busz buses were officially transferred to the Rotterdamse Elektrische Tram (RET), Rotterdam’s public transportation authority, in a ceremony last week under the Erasmus Bridge in downtown Rotterdam.

The 384V e-Traction e-Busz is the latest evolution of e-Traction’s Whisper 2 model. Recharged by both regenerative braking while driving and plug-in power during off-duty hours, the patented Valence Technology U-Charge batteries are designed to operate in fleet operations for 16 to 18 hours per day, the company said.

RJ Adleman, vice president of sales and marketing at Valence Technology, said: “Having experienced the e-Traction bus firsthand in Rotterdam, it is evident these smooth, silent and environmentally friendly commercial buses will help reduce carbon emissions and provide Rotterdam residents with green and enjoyable transportation for years to come.”

Upon successful completion of in-service testing by RET, the city of Rotterdam is expected to purchase additional e-Busz buses to integrate into its fleet of 238 diesel transit buses.
