Battery Box

Battery Box

IMG_1314The battery box is an essential part of our electrification solution. This approach allows for a centralised power production facility, our energy kiosks, and distribute the electricity for consumption using the boxes. This reduces significantly the infrastructure cost associated with a conventional grid.

First Generation 2009

Our first battery box offered 12V DC to run appliances such as light bulbs, radios and mobile telephones. However, during our implementation phase in September 2009 we notices that interfacing some of the appliances proved to be very difficult. We noticed that 12 V DC with our specialized plug proved to not allow the degree of flexibility conventional grid offers. It is important to remember that the target market are people that earn least in the world and their expected load profile can be estimated to be 40Wpeak.

Second Generation 2010

To extend the variety of appliances that can be used with the box, an inverter was integrated. Having a standard 230V AC plug allowed our customers to use AC lighting as well as all other standard low power appliances. The second generation box was decreased in size and weight to increase handiness.

Third Generation 2011

Problems concerning the inverter and the AC lighting in the second generation lead to a third box that combines the advantages of the previous models and minimises the weaknesses. Returning to the DC lighting uses less energy and the inverter is switched on only if needed.
