In 2022, their 20MW system cost €11.4 million. The 2024 expansion? Same capacity for €9.3 million. That’s a 18.4% price drop per megawatt. Even Santa’s workshop up in Lapland is switching to battery-powered elves these days! Here’s where Finland plays its trump card: extreme climate testing.
[pdf] For maximum performance and longevity, LiFePO4 batteries should be maintained within their optimal temperature window of approximately 15-35°C. This range ensures efficient electrochemical activity while minimising stress-related degradation.
[pdf] The recommended method for charging a LiFePO4 battery pack is the CCCV (Constant Current, Constant Voltage) approach: Constant Current: Charge the battery at a rate of 0.3C. Constant Voltage: Once the battery reaches 3.65V per cell, switch to constant voltage charging.
