The Internet of Things is a constantly evolving area. New generations of smart devices necessitating higher pulse currents, together with the advent of low powered networks, are changing the game and placing new demands and opportunities on batteries.
A good example of these evolutions is new smarter meters. They are making additional demands on their autonomous power supplies including higher power pulse capability and a wider operating temperature range, while long lifetime and ATEX compliance remain mandatory.
Two main trends in the smart/connected devices market are particularly instrumental in the development of batteries capable of sustaining high pulse currents while still ensuring a long lifetime:
- A massive worldwide adoption of the LPWAN communications protocols that require higher current peak values (pulses) to achieve a longer range of data transmission, even though they have lower power requirements than traditional cellular communication protocols.
- The reduction of the number of data concentrators deployed in the field as this helps in reducing the CAPEX of smart meters or smart devices projects.
Saft is constantly investing in research and development in order to address complex IoT designers’ needs. On top of the two ranges of battery technologies available for high pulse applications, spiral Li-SOCl2 (LS) and Li-MnO2 (LM), Saft is now launching a brand new range of batteries, the LSP range, to best match your use case. Spiral Li-SOCl2 - an ideal solution for applications requiring high pulse, even at low temperatures (LSH)
Saft’s new range of primary solutions –the LSP– combines reliable, low self-discharge Li-SOCl2 cell technology in parallel with a state-of-the art and carefully selected LiC (Lithium-ion Capacitor).
The LiC selected by Saft is showing the lowest self-discharge and ESR (Equivalent Series Resistance) at most temperatures and one of the highest measured capacitance during a pulse, ensuring that the LSP range will meet the lifetime of 10 years or more required by the new generation of connected devices. Saft also thoroughly tested a wide range of EDLCs and LiCs to ensure the best compromise between pulse sustaining capability, operating temperature range, and performance stability over lifetime. Eventually, the difference of the LSP consists in optimizing the combination of an Li-SOCl2 cell with an LiC supported by Saft’s proprietary sizing and lifetime calculation model.
With this new range of LSP batteries, Saft is now, more than ever, able to answer most of the challenges met by IoT designers.
