ABB announces flash charging electric bus pilot in Geneva

ABB has developed a new flash charging system for city buses, and is working with the city of Geneva’s public transport company and electric power utility SIG on a pilot project. The TOSA (Trolleybus Optimisation Système Alimentation) will be deployed for the first time on a 135-passenger electric bus. The system enables onboard batteries to… Read more »

Ultracapacitors creep into automotive

Maxwell looks to leverage its early ultracapacitor experience into a ubiquitous, low-cost, high-volume complement to batteries. Power sources like internal combustion engines and advanced battery packs work great as continuous suppliers of energy. But during the highest peak loads, both sacrifice efficiency attempting to meet the power delivery demands. And pushing these devices to their… Read more »

It’s in the details: Digatron Firing Circuits’ new stop-start testing rig

Digatron Firing Circuits’ new stop-start testing rig examines the limitations of lead-acid batteries and the inadequacy of traditional static tests. As the battery in a stop-start system ages, the fuel efficiency advantages are curtailed. It’s a real problem found in some first-generation systems, and has led many to question the methodology used in urban-efficiency tests…. Read more »
