Simulation results demonstrated that with this strategy it is possible to achieve double the fuel economy of a comparable conventional vehicle while satisfying all performance constraints. In addition, the final vehicle design provides an all-electric range capability in excess of 20 miles.","PeriodicalId":360008,"journal":{"name":"Sixteenth Annual Battery Conference on Applications and Advances.

Because of their small size, most of these applications have strict limitations on the available space and power dissipation and tend to use lithium-ion (Li-ion) batteries. This paper describes a charger design topology that moves the bulk of the power dissipation of battery charging out of the portable device but leaves the charger circuit embedded in the application. The performance of a circuit with high-accuracy voltage regulation, battery conditioning, temperature monitoring, and charge-status indication is analyzed for the effects of power dissipation, circuit area, and charging time.","PeriodicalId":360008,"journal":{"name":"Sixteenth Annual Battery Conference on Applications and Advances.

These effects can have profound influence on the measured values and can lead to erroneous conclusions in determining the state of health of the batteries.

Lithium ion batteries have started replacing conventional aerospace batteries, such as nickel-cadmium, nickel-hydrogen and silver-zinc, in NASA's planetary exploration missions, especially in applications where the cycle and active (wet) lives are moderate but the demands for reductions In mass and volume are significant. In addition, these applications require good low temperature performance for the planetary landers and rovers. In this context, NASA had teamed with DoD to form a consortium to develop smart, high-capacity, long-life, aerospace lithium ion batteries for both NASA and DoD needs, with the participation of domestic battery manufacturers. Prototypes of lithium ion cells, in capacities ranging from 4-40 Ah and in either prismatic or cylindrical configuration were made wider this program and are being tested at JPL. In this paper, the authors provide a description of the typical performance characteristics of these prototype lithium ion cells. Also included in the presentation is a brief mention on a couple of safety events experienced at JPL in the course of such extensive evaluation of several (over 200) cells under a variety of test conditions.","PeriodicalId":360008,"journal":{"name":"Sixteenth Annual Battery Conference on Applications and Advances.

Development in advanced battery simulation capability using computational fluid dynamics (CFD) techniques proved that this approach could have significant impacts on almost every aspect of battery design, characterisation, operation and development. Good predictions from the simulation however strongly rely on careful validation of the numerical model and the parameters used. This paper discusses how experimental validation work was conducted to support the simulation effort in valve-regulated lead-acid (VRLA) batteries. Of particular interest is the overcharging regime, where the experimental work is the most difficult and challenging, and the validation is the most needed for careful evaluation of the modeling capability and limitation.","PeriodicalId":360008,"journal":{"name":"Sixteenth Annual Battery Conference on Applications and Advances.
