Analysis: What Does This Simulation Prove?

What this proves: LiFePO4 and lithium batteries benefit from occasional full charges to balance cell voltages - typically every 2 weeks. This 16-day simulation shows peak shaving during normal operation, with the battery balancing feature charging to 100% SOC during off-peak night hours (00:00-06:00) when conditions are met. The system only triggers balancing when SOC reaches the threshold (>95%) naturally through overnight charging. This maintains battery health while still achieving significant peak reduction. Watch how the battery cycles daily for peak shaving, with the occasional full charge for cell balancing.

Monthly Cost Impact: Based on typical Swedish effekttariff rates (~50 SEK/kW/month), this 0.4 kW reduction saves approximately 19 SEK/month on the power tariff portion of your grid fee.

Battery Contribution: The battery discharged during 96 peak hours with an average discharge rate of 1.3 kW to shave consumption peaks.
