CHARGING SEALED BATTERIES

Journal of Educational Television, 1979
ABSTRACT Portable video recorders, cine cameras, audio recorders and a range of other products, rely upon the use of sealed rechargeable batteries as power sources. An experimental method for recharging sealed batteries that have been allowed to discharge too far, is described.

Battery Aging, Battery Charging and the Kinetic Battery Model: A First Exploration

2017
Rechargeable batteries are omnipresent and will be used more and more, for instance for wearables devices, electric vehicles or domestic energy storage. However, batteries can deliver power only for a limited time span. They slowly degrade with every charge-discharge cycle. This degradation needs to be taken into account when considering the battery in

Battery charging apparatus for series battery

Journal of Power Sources, 1998
A plurality of battery charging modules C, equal in number to a plurality of batteries B connected in series, are connected in series form a column of battery charging modules 6. Output terminals 7, 8 of this column 6 serve as the connecting terminals for a beginning terminal 2 and an ending terminal 3 of the series-connected column of batteries 1.

Photovoltaically Self-Charging Battery

Journal of The Electrochemical Society, 2002
For many low-power applications, solar cells are used as an environmentally friendly power supply. In order to provide electrical power also in the absence of solar radiation, we invented a device which unifies both a solar cell and a rechargeable battery in one unit. The main components are a photoactive layer on a charge-storage layer. Thus, this new

Feedback Control Battery Charging

INTELEC '82 - International Telecommunications Energy Conference, 1982
This paper describes a system capable of charging a lead-acid battery by cell control of the charging current without damage to any cell of the battery. This is accomplished by monitoring the temperature, voltage, specific gravity, and electrolyte level.

Battery Charge Condition Monitoring

SAE Technical Paper Series, 1974
<div class="htmlview paragraph">Basic techniques are presented for determining the charge condition of electric vehicle propulsion batteries of both the lead-acid and nickel-cadmium types. The techniques presented include those employing measurement of battery parameters, such as electrolyte properties, voltage, and internal resistance, and those

Batteries: Charging ahead rationally

Nature Energy, 2016
Redox mediators facilitate the oxidation of the highly insulating discharge product in metal–oxygen batteries during recharge and offer opportunities to achieve high reversible capacities. Now a design principle for selecting redox mediators that can recharge the batteries more efficiently is suggested.
