ISE Signs Exclusive 5-Year Agreement With Optare to Supply Ultracapacitor-based Energy Storage Systems for Buses
ISE CleanTech, Inc., a wholly-owned subsidiary of ISE Limited, a developer, manufacturer and distributor of energy storage systems (ESS) and heavy-duty hybrid-electric drive systems, signed a 5-year exclusive supply agreement with Optare UK Ltd, effective 21 June, for its ultracapacitor-based Ultra-E energy storage systems. ISE secured an initial order for 66 Ultra-E ES Systems with 22 systems to be delivered in 2010.
ISE also recently entered into an agreement with Maxwell Technologies, Inc. under which ISE will source ultracapacitor cells for use in its ultracapacitor energy storage systems exclusively from Maxwell through December 2011. (Earlier post.)
Optare, a leading manufacturer of electric and hybrid-electric vehicles, designs, manufactures, and sells single deck and double deck buses and mini coaches and offers post-sales service via operations throughout Continental Europe, North America, and elsewhere. On 10 May, Optare won an award for up to 66 units, or 100% of the hybrid bus order, from Greater Manchester Integrated Transport Authority (GMITA).
As not all hybrid buses are the same, we needed to ensure our low emission vehicles were each powered efficiently and effectively. After an extensive evaluation process, we choose ISE as our exclusive supplier for ultracapacitor-based ES Systems because of its rugged, modular and scalable designs. ISE’s Ultra-E ES System is clearly the best solution for our hybrid vehicles. We are confident that our selection of ISE will enable us to fulfill what represents the single largest order for hybrid buses so far to be placed with help from the Green Bus Fund. Our partnership also enhances Optare’s leadership position in this highly-competitive hybrid vehicle market.

According to Frost & Sullivan as of December 2009, the estimated global hybrid and electric heavy commercial vehicle demand, which represents part of the addressable market for energy storage systems, is expected to reach approximately 240,000 units produced by 2015.
The basic ISE ultracapacitor module is a liquid-cooled, 100 VDC, 0.1 kWh unit built with 48 ultracapacitor cells (Maxwell Boostcap 3000P). Capacitance is 62 F, total energy stored nominal is 105 Wh (peak 125 Wh). Rated power is 40 kW, and DC ESR is 16 mOhms. The units have a cycle life of 1 million (50% DoD).
ISE’s liquid-cooled Ultra-E ES System includes a battery management system that actively monitors each cell.
ISE specializes in series hybrid-electric and all-electric/zero emission technologies, and offers industry-leading ES Systems and Hybrid System components. Over the past 10 years, ISE has sold more than 300 hybrid systems with more than 13 million miles combined of fleet operation.
