Monitoring devices for the real estate industry fitted with Saft’s Li-SOCl2 primary lithium battery technology
This smart system for consumption reading, monitoring and billing is a key step in our strategy to become the digital partner of choice for the real estate industry. We needed absolute confidence that the batteries would offer excellent performance over a long service life.Dr. Arne Kähler Head of Research and Product Development at Techem
Techem, a leading global energy service provider for the real estate sector, has created an innovative smart reading system for utility meters, smart heat cost allocators and smoke detectors. The system monitors the device status as well as the heating and water consumption in a building thanks to wirelessly connected devices and sends consumption and status information per mobile communication via cloud to the Techem data center which then automatically creates billing and energy reports for the properties. Residents are informed of their exact consumption, thus promoting efficient, economical use of energy and water.
For the applications to be enduring and efficient, Techem needed a mature and reliable technology, capable of delivering the high pulse currents required for frequent wireless data transmission, even at the end of their life. The smart meters also had to offer a life expectancy of between 5 and 10 years.
To provide Techem with complete confidence in the battery’s capability, we carried out detailed modeling based on their device’s specific consumption profile and environmental parameters. The Li-SOCl2 electrochemistry that was specified for the smart reader feature has established a reputation for reliability and long life in smart metering applications for both water and gas, with hundreds of millions of batteries successfully deployed worldwide, hence our recommendation. More than 30 years of field and laboratory data enables us to accurately predict the expected life of our batteries in this type of demanding IoT application.
For Techem, the high level of technical support for the selection of the ideal power solution was decisive in the choice of the final provider.
