Tiny energy converters power sensors and switches, enabling them to function without batteries or wires and therefore work maintenance-free. Replacing batteries means expenditure, both from a hardware and maintenance perspective. EnOcean’s self-powered technology means no batteries need to be replaced, ever. This is particularly true in systems consisting of several tens, hundreds or thousands of wireless nodes as you find in the field of smart home and building automation.
Just think of a hotel, which has equipped each of its 400 rooms with four battery-powered sensors. Every two to three years, each one of these 1,600 batteries needs to be replaced – it is irrelevant if the devices are hard to access or hotel guests might be disturbed. Worse still is when batteries in a light switch or a remote control fail during guest usage. In commercial or industrial operation, a battery cost calculation must therefore be included to generate accurate lifetime costs covering maintenance efforts and proper hazardous materials disposal. Only Total Cost of Ownership (TCO) calculations reveal the true cost of battery-operated systems.
