Chapter 6: Pulse-Charging Battery Systems
It is possible to draw substantial amounts of energy from the local environment and use that energy to
charge batteries. Not only that, but when this method of charging is used, the batteries gradually get
conditioned to this form of non-conventional energy and their capacity for doing work increases. In addition,
about 50% of vehicle batteries abandoned as being incapable of holding their charge any longer, will
respond to this type of charging and revive fully. This means that a battery bank can be created for almost
no cost.
However, while this economic angle is very attractive, the practical aspect of using batteries for any
significant home application is just not practical. Firstly, lead-acid batteries tend to get acid all over the place
when repeatedly charged, and this is not suited to most home locations. Secondly, it is mended that
batteries are not discharged more rapidly than a twenty hour period. This means that a battery rated at a
capacity of 80 Amp-hours (AHr) should not be required to supply a current of more than 4 amps. This is a
devastating restriction which pushes battery operation into the non-practical category, except for very minor
loads like lights, TVs, DVD recorders and similar equipment with minimal power requirements.
The main costs of running a home are those of heating/cooling the premises and operating equipment like a
washing machine. These items have a minimum load capacity of just over 2 kW. It makes no difference to
the power requirement if you use a 12-volt, 24-volt or 48-volt battery bank. No matter which arrangement is
chosen, the number of batteries needed to provide any given power requirement is the same. The higher
voltage banks can have smaller diameter wiring as the current is lower, but the power requirement remains
the same.
So, to provide a 2 kW load with po
