It is valuable to study the combined system of lead-acid batteries and super-capacitors in the context of photovoltaic and wind power systems [8–10]. Battery is one of the most cost-effective energy storage technologies. However, using battery as energy buffer is problematic .
In this paper we investigate the technical feasibility of repurposing the standard ATX power supply found in many desktop computers into a 12V battery charger. We provide an overview of the ATX power supply before describing how the power supply may be modified into a battery charger alongside experimental results.
Lead–acid batteries have been used for energy storage in utility applications for many years but it has only been in recent years that the demand for battery energy storage has increased.
ICT equipment is usually replaced at regular intervals, usually before the equipment has failed, opening up the opportunity of providing a second-life through repurposing. In this paper we investigate the technical feasibility of repurposing the standard ATX power supply found in many desktop computers into a 12V battery charger.
Each battery is grid connected through a dedicated 630 kW inverter. The lead–acid batteries are both tubular types, one flooded with lead-plated expanded copper mesh negative grids and the other a VRLA battery with gelled electrolyte.
Currently, stationary energy-storage only accounts for a tiny fraction of the total sales of lead–acid batteries. Indeed the total installed capacity for stationary applications of lead–acid in 2010 (35 MW) was dwarfed by the installed capacity of sodium–sulfur batteries (315 MW), see Figure 13.13.
Proven Success Across the Globe in Diverse Sectors
During discharging, the lead oxide on the lead plates is converted into lead. The acid content decreases because sulphuric acid is required for this process. To recharge the battery, an external power source - such as a battery charger, alternator or solar panel - with a voltage of around 2.4 V per cell must be connected.
What is important is what comes out of that power supply, I.e., 9V. To run it off a battery, you would not use the AC adapter. You would connect your DC 9V source to a plug identical to the one coming out of the adapter and plug that into the power jack on the tablet. A small 9V battery is not sufficient. Your best bet would be a lithium battery.
