Recommendations for New Safety Requirements and Research

Robert Thomson

The main objective of EVERSAFE is to facilitate integration of electrical vehicles (EVs) into European vehicle traffic. Customer acceptance increases when EV safety is guaranteed for normal operation or an accident. The EVERSAFE project had three main areas of research to ensure a robust market for EVs:

  1. The perceptions of electric vehicles from a user point of view
  2. Investigations of vehicle safety encompassing both active and passive vehicle safety implications that are part of the vehicle’s design
  3. Developing guidelines and recommendations for post-crash handling of electric vehicles that are not addressed in the practice for conventional (internal combustion) drivelines

The research plan was developed to identify the most high risk scenarios, investigate their potential consequences, and identify any corrective actions in terms of further research, industry standards, or government regulations.

The project used focus groups of consumers to identify perceived issues as well as expert judgement to identify specific research cases.

The main findings of the active safety investigations suggested that the potential failures for regenerative braking and wheel hub motors could be compensated by the drivers.

Passive safety investigations used component tests of battery cells, full scale crash tests, and numerical simulations to study the risks during a crash.

The safe handling of electric vehicles after a crash requires updates to the conventional rescue operations.

The results of the EVERSAFE project indicate that the general level of EV safety is quite high and that no critical safety issues have been identified.

Electric scooters are making their way into the accident statistics

The number of accidents involving electric scooters has increased from a few in 2017 to almost 500 in 2019 (January - October). This was also when electric scooters really made their entrance into Sweden's largest cities.


How can the bus trip be improved for people with ADHD?

People with autism, ADHD and other neuropsychiatric disorders may experience difficulties in using public transport, which limits their opportunities for an active life in terms of school, work and hobbies.


Evolution Road – new electric road tested both inside and out

In the beginning of May, the next-generation electric road was inaugurated in the city of Lund in southern Sweden. Ground based conductive charging technology will be tested on a kilometre long stretch of electric road in the bus lane in Getingevägen. This...


Additional policy instruments are needed to achieve Swedish environmental quality objectives for maritime transport

Achieving the national and international environmental objectives for maritime airborne emissions requires a combination of new and more powerful policy instruments. The policies already in place are not enough. This is one of the conclusions of a research...


Opportunities for a new market in electrified regional flight

Large, electrified aircraft is far off in the future. On the other hand, there may be potential for a new market with smaller regional flights. These are the conclusions of a literature survey made by researchers at VTI.


Need for standards as electric road systems are developed

The need for standardisation is increasing as electric road systems are reaching higher levels of maturity. A large part of the standards for intelligent transport systems (ITS) assessed in a new VTI and SIS study was considered potentially useful for...
