About Photovoltaic Energy StorageElectrical imbalances occur during charging and discharging of battery packs. Some cells in a battery will have different voltage levels for the same charging. This mismatch needs to be monitored to improve efficiency and safety of battery pack. Higher than rated temperatures in the batteries lead to undesirable chemical effects.
About Photovoltaic Energy StorageA. State of Charge (SOC) Unbalance State of charge unbalance is caused by cells being charged to different state of charge (SOC) levels. For example if we have 3 x 2200mAh cells (Qmax), and discharge one by 100mAh (Q1), second by 100mAh and third by 200mAh from a fully charged state, the first and second
