Operation and Maintenance of Battery Charging Systems (BCS)

Not considering generation issues here, one of the most crucial points concerning the operation of professional BCS is the need for trained personnel. Another important point is how transport of the batteries from the BCS to the consumer is organized (in the case of central BCS in neighbouring villages, for example). This can either be the responsibility of the resident or a service provided by the station. This question is of particular relevance mainly because of possible human injuries related to spilling of acids during transport. Also the weight of the batteries should be considered (because of a given energy-density, batteries of a useful stored capacity often weigh around 20 kgs). Besides that, it is an interesting question whether batteries should be privately owned or lent/leased by a firm.

There are several advantages of operating a BCS as a lease system. These include possible standardization of batteries (allowing for better handling and therefore cost savings), cost leverage from bulk purchase (allowing for cheaper recharge rates) and maintenance services according to a set schedule.

The greatest technical risk of BCS, namely over discharge of batteries, is most probably effectively solved by an ownership model. In this case the individual would be responsible for his/her own battery maintenance and, therefore, less likely to over discharge the battery. Therefore, the sound introduction of standardized batteries in the market through a lease model seems to be a feasible option. This way, costumers with very low incomes would be enabled to benefit from the system while developing a certain sense of care for their system.
