41 HOW IT WORKS Electric vehicles ESTIMATED TIMEFRAME 2008 > ONGOING HOW IT WORKS KNOWLEDGE CENTRE 1 WHAT ARE ELECTRIC VEHICLES? As the name suggests, electric vehicles have an electric motor, which they rely on partly or entirely for power. They store power in a battery as opposed to a fuel tank and require charging via a cable plugged into an electric power source, which can take hours as opposed to the minutes it takes to refuel at a petrol station. Mitsubishi, Nissan and Holden launched electric vehicles in 2012. Renault, Ford, Toyota, BMW, Tesla and Porsche all have models in the pipeline. 2 WHY USE THEM? Electric vehicles o er a number of bene ts. Greenhouse gas emissions are reduced, particularly if they are run on renewable energy. Without exhaust fumes, local air quality should improve while noise pollution from tra c noise should also be reduced. The batteries can also be recycled. Up front costs of purchasing an electric vehicle can be high, but running costs are lower than your typical combustion engine vehicle. There are also economic bene ts of using locally sourced energy and users bene t from greater energy security. 3 WHAT TYPES OF ELECTRIC VEHICLES ARE THERE? The type of electric vehicle varies depending on their reliance on electricity. Hybrid electric vehicles (HEVs) use liquid fuel as their main source of energy, but supplement this with electrical energy captured from the braking system and stored in batteries. Plug-in hybrid electric vehicles (PHEVs) use liquid fuel and electrical energy from an external source via a plug. Battery electric vehicles (BEVs) are solely powered by electricity. 4 TRIALS The Victorian State Government has completed an electric vehicle trial to better understand the process, time lines and barriers for transitioning to electric vehicle technologies. The trial was launched in October 2010 and ran until mid-2014. More than 80 organisations took part in the trial, which is part of a $5m initiative of the Victorian Government. The trial included household vehicle, eet vehicle and charging infrastructure roll out. A full report of the trial is stil to be released.
