Description
Lithium batteries are constantly evolving. Their applications are diverse and varied, ranging from small portable electronic devices to large energy storage. These batteries offer the best specific energy (capacity/weight ratio) on the market, have a longer lifespan, and can have high depths of discharge. They operate in extreme environments. This makes them ideal for International Monitoring System (IMS) sites which have difficult access, or have off-grid or unreliable power supplies. However, some of the less positive aspects of this technology are often overlooked. In addition to the environmental impact (mining and pre-treatment processes, and limited recycling of batteries thereafter), their energy-intensive manufacturing process is one of the reasons for their sometimes exorbitant prices. Their transport also requires special precautions (strict regulations). Using lithium batteries outside the manufacturer's specifications will shorten their service life and, in the worst cases, may lead to fire or explosion. To optimize such an investment and benefit from its advantages, the IMS needs to carry out preliminary engineering studies for each site before installation, install and configure high-performance battery management systems and train station operators for the monitoring and maintenance.
