WebFeb 1, 2024 · The SOH is calculated by comparing the current C/3 discharge capacity to the initial C/3 discharge capacity of a fresh cell. The cycle ageing tests of the LFP cells lasted in total 190–1020 days including the time required for reference performance tests. Some of the LFP cells have long testing times due to idle time between the tests. WebJul 22, 2024 · And SOH CAH TOA problems can appear near the beginning, in the middle, or near the end of an exam. In other words they can be easy, medium in difficulty, or tough. But if you know the trig rules well and have had a little practice, even tougher end-of-the-test versions can be manageable.
