The Brookville Liberty Modern Streetcar is equipped with 750 V DC onboard battery packs made up of rechargeable lithium-ion batteries, referred to as an onboard energy storage system (OESS), that enable it to operate off-wire. [3] [8] It is the first electric streetcar built in the United States capable of operating off-wire. [6]
The first battery buses were mostly small, mini- or midi- buses. The improvement of battery technology from around 2010 led to the emergence of the mass-produced battery bus, including heavier units such as 12.2-meter (40 ft) standard buses and articulated buses. China was the first country to introduce modern battery electric buses in large scale.
The Chollima-321 (Korean: 천리마-321) is a North Korean trolleybus with battery power built by the Pyongyang Trolley Bus Factory. [1] The name 'Chollima' refers to a myth about a winged horse that has since been adopted as the name of North Korea's Stakhanovite movement. [2]
The buses have a battery capacity of 170 kWh and a range of 80 kilometres. They are charged during the day by Heliox 450 kW fast chargers, taking between 15 and 25 minutes. Overnight, 30 kW slow charges take 4–5 hours. [119] They are powered by 100% renewable energy, from wind power and solar panels at the depots. [120]
The first battery electric Xcelsior buses were a powertrain option within the regular Xcelsior line; development was announced in 2011, a prototype was shown in 2012, and regular production began in 2014. [10] The original battery electric Xcelsior bus, offered as an XE40, used a permanent magnet traction motor built by Siemens. [11]
Boston Neoplan DMA-460LF dual-mode trolleybus, operating in diesel mode (with its trolley poles lowered). A dual-mode bus is a bus that can run independently on power from two different sources, typically electricity from overhead lines like a trolleybus or from batteries like a hybrid bus, alternated with conventional fossil fuel (generally diesel fuel).
