Solo and Versa EV
All electric citybus vehicles
Optare - The background
• Significant investment in ‘Low carbon’ bus development • Strategic investor – Ashok Leyland of India • New factory opened in November 2011 Optare – The future
• We see the future as Electric – key drivers • Euro 6 impact • Reduc on in BSOG and increasing fuel costs • Operators want fixed running costs • Lower maintenance costs • Global compe on – we have the edge EV – It’s Electric!
• Externally and internally, the Solo and Versa EV look just like their diesel counterparts. • Excep onal passenger capacity is maintained (in excess of 50 on 11.1m Versa). • Performance matches a diesel vehicle. • Delivers commercial benefits. • Has a minimal environmental impact including zero tailpipe emissions and low noise. What is the EV driveline? • A standard vehicle with a self-contained electric power pack in place of the conven onal diesel/ gearbox/radiator power pack. • No intrusion into passenger compartment. • No roof mounted equipment. • Magtec systems P144 "Zero Emission” electric vehicle drive system. 150kW, 2380Nm. Drivetrain
• 358 Volts • 2 x 26 Valance Lithium Iron Magnesium Phosphate U27 - 12XP 12.8V, 138Ah maintenance free ba eries. Ba ery System Features • Low weight ba eries do not significantly effect overall passenger capacity. • A ba ery management system con nuously monitors state of charge, logs and reports condi on. • A 15.2kW on-board charger can be plugged into a standard industrial 3 phase socket enabling a full charge to be achieved in 6 hours. • 50kW off-board charging op on available for full charge in only 2 hours. Can be le una ended. • Opportunity charging can be undertaken through the day allowing range to be extended to make the Versa EV viable across a much wider spread of public transport opera ons. Ba ery System Features Vehicle Opera ng Cost • Opera onal range – 70 to 95 miles. • Lower maintenance costs - only 3 moving parts in an electric motor - over a 1000 in a combus on engine. • The motor drive system and ba eries are sealed and are maintenance free. • Maintenance cost savings circa £1,800/annum. • Zero vehicle excise duty. • Commercial payback possible within four years*. • Forecast rise in diesel fuel costs.
• Zero emissions and 30,000kg of CO2 saving. * Source routeONE road test, 28 March 2013
Low weight integral structure
Class leading unladen weight The driving experience • All controls are the same as a diesel powered vehicle. • The system’s accelera on control func on delivers a managed and comfortable rate of accelera on. • Vehicle top speed is 56mph (90km/h). This can be limited to a lower speed for greater energy conserva on. • Regenerated energy controlled through the brake system, is stored and used to enhance opera onal range. • Driver vehicle interface for reduced energy consump on.
The passenger experience • Low-floor, easy-access for all passengers, whatever their level of mobility. • Stylish modern design both inside and out for instant passenger appeal. • Low vibra on levels induced into the vehicle aid passenger comfort as well as prolonging component life. • Low interior noise levels. • Smooth accelera on and braking. • Safe in the knowledge that they are helping to protect the environment. Serviceability, Diagnos cs and Telema cs
• Ba ery packs can be dismounted separately. • On-board diagnos cs for rapid fault tracing. • Telema c system for instant feedback on. • Vehicle tracking facility. Benefits of the EV driveline • Lower opera ng costs – Lower fuel cost – Lower maintenance costs – No road tax – Higher residual value poten al • Being, and being seen to be GREEN – Protec on of the local environment – Compe ve edge in winning business – Improved travelling experience • Many components from the well proven Versa and Solo. The Optare Solo and Versa EV • Optare is pioneering modern day full-size ba ery- powered buses in the UK. • Optare is the only UK manufacturer of such vehicles. • Three years of development began in 2009 with extensive trials of Solo EV 27-seater midibus model leading to the development of Versa EV and fast charge systems. • Ideal for buses due to set route and back to base opera on. • Currently seventeen vehicles in revenue service in the UK with a further twenty two due to enter service later this year.
