Further demonstration of the VRLA-type Ultrabattery under medium-HEV duty and development of the flooded-type Ultrabattery for micro-HEV applications
Journal of Power Sources, 2010Co-Authors: Jun Furukawa, T. Takada, D. Monma, L.t. LamAbstract:Abstract The Ultrabattery has been invented by the CSIRO Energy Technology in Australia and has been developed and produced by the Furukawa Battery Co., Ltd., Japan. This battery is a hybrid energy storage device which combines a super capacitor and a lead-acid battery in single unit cells, taking the best from both technologies without the need of extra, expensive electronic controls. The capacitor enhances the power and lifespan of the lead-acid battery as it acts as a buffer during high-rate discharging and charging, thus enabling it to provide and absorb charge rapidly during vehicle acceleration and braking. The laboratory results of the prototype valve-regulated UltraBatteries show that the capacity, power, available energy, cold cranking and self-discharge of these batteries have met, or exceeded, all the respective performance targets set for both minimum and maximum power-assist HEVs. The cycling performance of the UltraBatteries under micro-, mild- and full-HEV duties is at least four times longer than that of the state-of-the-art lead-acid batteries. Importantly, the cycling performance of UltraBatteries is proven to be comparable or even better than that of the Ni-MH cells. On the other hand, the field trial of UltraBatteries in the Honda Insight HEV shows that the vehicle has surpassed 170,000 km and the batteries are still in a healthy condition. Furthermore, the UltraBatteries demonstrate very good acceptance of the charge from regenerative braking even at high state-of-charge, e.g., 70% during driving. Therefore, no equalization charge is required for the UltraBatteries during field trial. The HEV powered by UltraBatteries gives slightly higher fuel consumption (cf., 4.16 with 4.05 L/100 km) and CO 2 emissions (cf., 98.8 with 96 g km −1 ) compared with that by Ni-MH cells. There are no differences in driving experience between the Honda Insight powered by UltraBatteries and by Ni-MH cells. Given such comparable performance, the Ultrabattery pack costs considerably less – only 20–40% of that of the Ni-MH pack by one estimate. In parallel with the field trial, a similar 144-V valve-regulated Ultrabattery pack was also evaluated under simulated medium-HEV duty in our laboratories. In this study, the laboratory performance of the 144-V valve-regulated Ultrabattery pack under simulated medium-HEV duty and that of the recently developed flooded-type Ultrabattery under micro-HEV duty will be discussed. The flooded-type Ultrabattery is expected to be favorable to the micro-HEVs because of reduced cost compared with the equivalent valve-regulated counterpart.

the Ultrabattery a new battery design for a new beginning in hybrid electric vehicle energy storage
Journal of Power Sources, 2009Co-Authors: A. Cooper, L.t. Lam, J. Furakawa, M. KellawayAbstract:Abstract The Ultrabattery, developed by CSIRO Energy Technology in Australia, is a hybrid energy storage device which combines an asymmetric super-capacitor and a lead–acid battery in single unit cells. This takes the best from both technologies without the need for extra, expensive electronic controls. The capacitor enhances the power and lifespan of the lead–acid battery as it acts as a buffer during high-rate discharging and charging, thus enabling it to provide and absorb charge rapidly during vehicle acceleration and braking. The initial performance of the prototype UltraBatteries was evaluated according to the US FreedomCAR targets and was shown to meet or exceed these in terms of power, available energy, cold cranking and self-discharge set for both minimum and maximum power-assist hybrid electric vehicles (HEVs). Other laboratory cycling tests showed a fourfold improvement over previous state-of-the-art lead–acid batteries under the RHOLAB test profile and better life than commercial nickel/metal hydride (NiMH) cells used in a Honda Insight when tested under the EUCAR HEV profile. As a result of this work, a set of twelve 12 V modules was built by The Furukawa Battery Co., Ltd. in Japan and were fitted into a Honda Insight instead of the NiMH battery by Provector Ltd. The battery pack was fitted with full monitoring and control capabilities and the car was tested at Millbrook Proving Ground under a General Motors road test simulation cycle for an initial target of 50 000 miles which was extended to 100 000 miles. This was completed on 15th January 2008 without any battery problems. Furthermore, the whole test was completed without the need for any conditioning or equalisation of the battery pack.

SECONDARY BATTERIES – LEAD– ACID SYSTEMS | Supercap Hybrid (Ultrabattery™)
Encyclopedia of Electrochemical Power Sources, 2009Co-Authors: L.t. Lam, J. FurukawaAbstract: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. The performance and cost (capital and running) of the devices for the electrochemical conversion and storage of energy are of great concern. The Ultrabattery™, developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia, is a hybrid energy storage device that combines a supercapacitor and a lead–acid battery in a single unit; it takes the best from both technologies without the need for extra expensive electronic controls. The supercapacitor enhances the power and lifespan of the lead–acid battery as it acts as a buffer during high-rate discharge and charge. Thus, the Ultrabattery in a hybrid electric vehicle enables the rapid delivery and acceptance of charge during vehicle acceleration and regenerative braking, respectively. When applied to the storage of wind energy, the Ultrabattery can also absorb the noise generated by the variation in wind speed and thereby deliver a smooth power output from the turbine.

Advanced Lead–Acid Batteries and the Development of Grid-Scale Energy Storage Systems
Proceedings of the IEEE, 2014Co-Authors: Brian B. Mckeon, Jun Furukawa, Scott FenstermacherAbstract:This paper discusses new developments in lead–acid battery chemistry and the importance of the system approach for implementation of battery energy storage for renewable energy and grid applications. The described solution includes thermal management of an Ultrabattery bank, an inverter/charger, and smart grid management, which can monitor the state of charge (SoC) and the state of health (SoH) of the battery during system operation. With such features, it can allow the battery to operate within an optimum SoC window and thus can further maximize the longevity of the Ultrabattery. Importantly, the smart battery management can trend the SoH of the battery and allow cell replacement at a convenient time without affecting the system operation. Furthermore, the advanced system package allows remote monitoring and control of operation, thus reducing the running cost of the system. It is clear that the widespread use of renewable-energy systems, in turn, would lead to a reduction in global consumption of the limited supplies of the fossil fuels and in the associated production of greenhouse-gas emissions.

Development of The Ultrabattery for Micro- and Medium-HEV Applications
2008Co-Authors: Jun Furukawa, Toru Mangahara, L.t. LamAbstract:Nowadays, there is a growing concern about global warming and the limited supply of fossil fuel. As a result, there is a strong push for automobiles with reduced CO2 emissions and improved fuel economy. In Europe, for example, various governments demand automakers to decrease CO2 emissions from current value of about 160 g for every 1 km driven to 140 g by 2008 and this is expected to decrease further to 120 g/km by 2012. Likewise, the Japanese government requires automakers to improve fuel economy from the present value of 13.6 km/L to 17.2 km/L by 2015. With such requirements, clearly, the micro (12V) / medium (144V) / full (>200V) -hybrid electric vehicles (HEV) will become the main stream in the near future.

vrla Ultrabattery for high rate partial state of charge operation
Journal of Power Sources, 2007Co-Authors: L.t. Lam, Jun Furukawa, T. Takada, D. Monma, Rosalie Louey, Nigel Peter Haigh, O V Lim, D G Vella, C G Phyland, T KanoAbstract:Abstract The objective of this study is to produce and test the hybrid valve-regulated Ultrabattery designed specifically for hybrid-electric vehicle duty, i.e., high-rate partial-state-of-charge operation. The Ultrabattery developed by CSIRO Energy Technology is a hybrid energy-storage device, which combines an asymmetric supercapacitor, and a lead-acid battery in one unit cells, taking the best from both technologies without the need for extra, expensive electronic controls. The capacitor will enhance the power and lifespan of the lead-acid battery as it acts as a buffer during high-rate discharging and charging. Consequently, this hybrid technology is able to provide and absorb charge rapidly during vehicle acceleration and braking. The work programme of this study is divided into two main parts, namely, field trial of prototype Ultrabatteries in a Honda Insight HEV and laboratory tests of prototype batteries. In this paper, the performance of prototype Ultrabatteries under different laboratory tests is reported. The evaluation of Ultrabatteries in terms of initial performance and cycling performance has been conducted at both CSIRO and Furukawa laboratories. The initial performance of prototype Ultrabatteries, such as capacity, power, cold cranking and self-discharge has been evaluated based upon the US FreedomCAR Battery Test Manual (DOE/ID-11069, October 2003). Results show that the Ultrabatteries meet, or exceed, respective targets of power, available energy, cold cranking and self-discharge set for both minimum and maximum power-assist HEVs. The cycling performance of prototype Ultrabatteries has been evaluated using: (i) simplified discharge and charge profile to simulate the driving conditions of micro-HEV; (ii) 42-V profile to simulate the driving conditions of mild-HEV and (iii) EUCAR and RHOLAB profiles to simulate the driving conditions of medium-HEV. For comparison purposes, nickel–metal-hydride (Ni–MH) cells, which are presently used in the Honda Insight HEV, have also been subjected to some of the above profiles (i.e., simplified discharge and charge profile and EUCAR profile). Although the Ultrabattery and a Ni–MH cell under EUCAR test profile are still on cycling, the outcomes to date show that the performance of these batteries and cells has been at least four times longer than that of the state-of-the art lead-acid cells or batteries. Excitingly, the performance of Ultrabatteries is proven to be comparable with that of the Ni–MH cells.

Technological Trends in Lead-Acid Batteries for Automotive Applications
2007Co-Authors: Kenji Nakano, Syuhei Takeshima, Jun FurukawaAbstract:In recent years performance requirements with respect to lead-acid batteries for automotive applications are beginning to undergo major changes as the vehicles themselves change. In addition to the traditional “SLI functions” (starting, lighting and ignition), there is also a need to provide advances in technologies for environmental improvement, batteries for accessory applications (power steering, stabilizers, etc.), new functions such as alternator control for charging controls aimed at suppressing gaseous emissions and improving fuel economy, stopping of idling, and regenerative braking. Furukawa Battery is engaged not only in basic technology and product development for lead-acid batteries to meet these requirements but also in developing the “Ultrabattery”--a new type of lead-acid battery that will meet the sophisticated requirements of next-generation vehicles.

Different paste techniques of negative plate of Ultrabattery under HRPSoC
Chinese Journal of Power Sources, 2013Co-Authors: Fang Ming-xueAbstract:The Ultrabattery is a new hybrid energy storage device which combines an asymmetric supercapacitor and a lead-acid battery in one unit cell that has great advantages in terms of good performance,long cycle-life and high specific energy and specific power.It acts as a buffer during high-rate charging and discharging,therefore it enables to provide and absorb charge rapidly during vehicle acceleration and braking.Consequently,it can reduce the cost and increase batteries cycling lifetime.The influence of different negative active materials paste techniques on the 12 V/10 Ah Ultrabattery was discussed in this article.The results show that battery with wet mixing paste technique manifests better performance with more longer cycling life.The cycling life experiments demonstrate that the life cycles can reach 6 972.The SEM patterns indicate that the size of negative active particles with wet mixing paste technique is smaller and homogeneous distribution.The XRD analysis results show that the wet mixing paste technique is useful to crystallize the negative active material.From the fitting of EIS patterns,it is known that the wet mixing paste technique can improve the capacitive of negative material,and decrease the resistance of ion transfer between the Millipore and particles to improve the electrochemical activity.

Study on the hybrid negative plates for Pb-C ultrabatter
Chinese Labat Man, 2011Co-Authors: Fang Ming-xueAbstract:The ultrabatteries are now a field to which many researchers have paid their attention.The key to produce Ultrabattery is the technology of negative plate.Based on the study of the influence of different carbons on the hybrid negative plates,we prepared ultrabatteries with high discharge capcity.The results of electrochemistry cyclic voltammetric measurement show that,when the activated carbon content is 1.0 %,the reversibility of hybrid negative electrode is best,and when the activated carbon content is 8.0 %,the electrode is characterized by good capacitance performance.When the spherical graphite was added to hybrid negative plates which can effectively inhibit the agglomeration of lead in the negative plates,the ultrabatteries have the best discharge performance at low temperature,less water loss and less change of internal resistance.
