Corvus Energy’s marine lithium polymer battery pack used in Europe’s first hybrid tugboat

Green Car Congress

Lithium polymer battery packs from Corvus Energy were recently installed in Europe’s first hybrid tugboat, the RotorTug RT Adriaan of KOTUG, an international maritime service provider headquartered in The Netherlands. This diesel-to-hybrid retrofit represents Europe’s first low emissions hybrid tugboat. Earlier post.)

UK Collaboration Develops Plug-in Hybrid Retrofit for Conventional Vehicles

Green Car Congress

A collaboration led by the UK’s Cranfield University has developed a retrofit plug-in hybrid conversion system for a conventional internal combustion engine vehicle. This transformed the van into a hybrid vehicle capable of achieving an all-electric range of more than 20 km (12 miles) on one charge. Earlier post.). The approximately 4.8

Practical aspects of off-grid EV charging

Charged EVs

An off-grid energy system basically consists of just four key components: 1) a battery to store energy; 2) one or more renewable energy sources (e.g. If that isn’t an option (perhaps because the off-grid location isn’t yet up and running) then you can estimate the power demand with rules of thumb (e.g. from the battery.

Ionova Technologies says ZIP-Cap ultracapacitors can offer 5x increase in energy density and 25x reduction in build cost (updated with graphic)

Green Car Congress

This can be a big problem for users of an ultracapacitor since DC-DC converters necessary to most ultracap applications require cell voltage be maintained above 1/2 full cell voltage. While emerging new converters. facilities used for electrolytic capacitors as well as lead/acid and alkaline. batteries to be leveraged.
