Battery degradation is defined in three ways: when the battery has reached 85% of design life. when capacity is below 90% of rated. when capacity has decreased more than 10% since the last test. When any of these are observed, it is recommended to then test at one-year intervals until capacity reaches 80% of rated.
The system displayed the potential for reducing peaks as well as reducing the energy consumption by 4%, even though the thermal storage capacity was only partly utilized in this test. The average return temperatures to the district heating system were also reduced by 2 °C while the system was in operation [9].
