ABB showcases EV innovation at Davos

Buses can recharge batteries in just 20 seconds as passengers board and disembark

The city of Davos, Switzerland, has teamed in a long-term partnership with ABB to provide e-infrastructure for public and private transportation, some of which will be on display at this year’s annual World Economic Forum (WEF). The forum takes place 23-26 January 2018.


In Davos, the TOSA bus, developed by the Swiss power and automation group, will operate on the busy Line 1, running from the tourist centre to the hospital. This is the first time ABB’s TOSA technology is being used in an Alpine region.


The idea is to run the system under extreme winter weather conditions; ABB and its project partners expect to gain valuable insights from the pilot project. The bus is already in use in Geneva and will soon be implemented in the French city of Nantes.


In addition, electric cars transporting attendees around Davos will be able to recharge their batteries at eight newly installed ABB fast-charging stations.


“The shift to electric vehicles (EVs) is no longer a question of if, but rather of when and how quickly,” said Ulrich Spiesshofer, CEO, ABB. “EVs are becoming increasingly attractive to motorists. As well as being ecologically responsible, they’re becoming less expensive to buy and maintain.”


At Davos, world leaders and WEF guests will be able to see eight recently installed ABB Terra 53 charging stations in action. ABB claims the Terra 53 is the best-selling 50 kW DC charging station in Europe and North America, supporting the CCS, CHAdeMO and simultaneous 22 kW AC charging standards.


The TOSA technology in use at Davos has been powering buses on Geneva’s bus line 23 airport route. They use overhead contacts that connect at selected stops along their routes to replenish their batteries in as little as 20 seconds, recharging as passengers board and exit. The environmentally friendly system in Geneva could ultimately cut carbon dioxide emissions by 1,000 tons annually, said ABB.


TOSA received the prestigious Watt d’Or 2018 in the energy efficient mobility category from the Swiss Federal Office of Energy. The TOSA technology was jointly developed in Switzerland by ABB in partnership with Transport Publics Genevois (tpg), the Office de Promotion of Industries et des Technologies (OPI), the Services Industriels de Genève (SIG), and bus manufacturer Carrosserie HESS.
