![]() ![]() Nevertheless, the running cost of the VRLA battery is expensive because of the short service life. The VRLA battery has the great advantages in terms of low initial (capital) cost, well established manufacturing base, distribution networks and high recycling efficiency (about 95%) compared to the other competitive technologies at their current stage of development. Since these vehicles are still under development and improvement, lower emission and lower fuel consumption, hybrid electric vehicles (HEVs) have been developed and commercialised for use during this transition phase.Īt present, candidate energy storage systems for HEV applications include valve-regulated lead-acid (VRLA), nickel-metal hydride (NiMH), rechargeable lithium batteries, and supercapacitor. The zero-emissions vehicles encompass electric vehicles and/or fuel-cell vehicles, which use alternative fuel, such as hydrogen, produced without greenhouse gas emissions. To tackle these issues effectively, there is an increasing demand for high performing rechargeable batteries to assist the development of zero-emissions vehicles (ZEVs) and the exploitation of renewable energy. The storage of energy particularly electrical energy has gained greater importance than ever before, mainly due to the strong world-wide concern over global warming and the depletion of the fossil fuels. Hybrid-electric vehicles and energy-storage systems UltraBattery® technology forms the basis for the Ecoult system. Ecoult battery technology aims to deliver a low-cost, high-performance, high-power, stationary energy storage solution suitable for grid-connected and remote applications. CSIRO and Cleantech Ventures have also invested in technology start-up Ecoult Pty Ltd to develop and commercialise battery-based storage solutions. The UltraBattery® technology has been licensed to the Furukawa Battery Co., Ltd, Japan and the East Penn Manufacturing Co., Inc., USA. This, in turn, will reduce the global consumption of fossil fuels and the production of greenhouse gas emissions. In wind turbine applications it can also absorb the noise generated by the variation in wind speed, delivering a smooth power output.įor both advanced automotive applications, and grid-connected wind energy applications, UltraBattery® has shown excellent performance and has the potential to remarkably improve the economic viability, and therefore the ‘uptake rate’ of HEVs and better utilisation of renewable energy. Thus, the UltraBattery® in a hybrid electric vehicle is able to deliver and absorb charge rapidly during vehicle acceleration and regenerative braking, respectively. The supercapacitor enhances the power and lifespan of the lead-acid battery as it acts as a buffer during high-rate discharge and charge. The UltraBattery®, developed by CSIRO Energy Technology in Australia under the leadership of Lan Lam, is a hybrid energy storage device which combines a supercapacitor and a lead-acid battery in a single unit cell, taking the best from both technologies without the need for extra expensive electronic controls. capital and running cost) are of great concern. The electric energy storage/conversion devices are inevitable parts of these applications and hence their performance and cost (e.g. ► High security.There is an increasing demand for the use of hybrid/full-electric vehicles (vehicles powered by batteries and/or fuel cells) and renewable energy (mainly wind and solar energy) to save fuel and reduce emission of carbon dioxide. ► Higher discharge rate, faster charging and dischargingWhen there is a need for backup power supply for a period of 10 hours or less, we could reduce up to 50% of the capacity configuration, comparing to lead acid battery. ► Cycle durability for a single cell is 2000 cycles, which is 3 to 4 times more than the cycle durability of a traditional lead acid battery. ► Broad temperature adaptability. Products perform well at a temperature of -20☌ to 60☌, without air conditioning system. ► Energy conversion rate is 15% higher than that of a traditional lead acid battery, the advantage of energy saving is obvious. Self-discharge rate < 2% per month. ► Energy density is high. The volume and weight of lithium battery is 1/3 to 1/4 of the traditional lead acid battery with the same capacity. ![]() Lithium Iron Phosphate (LiFePO4)Battery, the longest life among battery field.ĭesigned floating service life: over 20years usage: 100%DOD, >2000 cyclesĬSPOWER LiFePO4 battery is newest lithium iron battery adopts advanced technology, Own Longest Cycle Life: Offers up to 20times longer cycle life and five times longer float /calendar life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership.Īdvantages for CSPOWER Lithium Iron Battery
