Podpoint makes electric charging terminals for vehicles that are spread around London. They came to us with a brief that looked into expanding their business with a home battery storage solution for people with solar panels. We did a deep dive into batteries and solar panels and our conclusion was that a standard battery storage for houses in the UK does not make sense. This is because there isn’t enough sunshine to produce that kind of energy that competitors like the Tesla Powerwall are using. Instead, we suggested a product-service-system design for a portable battery that was small enough to be charged with UK sunlight and also be transported for different use cases: an extra battery for the user’s electric vehicle or for outdoor battery needs like camping or filming.
