Free QuoteGenerally, the battery storage unit's initial state of charge (SOC) is inconsistent, . It is easy for some energy storage units to exit operation prematurely due to energy depletion, leading to the reduction of available capacity and the removal of power supply reliability of the power system, , .
The state of charge influences a battery's ability to provide energy or ancillary services to the grid at any given time. Round-trip eficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.
Also, overcharging can cause unstable conditions. To increase battery cycle life, battery manufacturers recommend operating in the reliable SOC range and charging frequently as battery capacity decreases, rather than charging from a fully discharged SOC or maintaining a high SOC.
GivEnergy home batteries will charge and discharge intelligently by default, taking advantage of cheaper energy rates. However, you can also take a more hands-on approach by setting schedules and timers around your energy usage and lifestyle. You can do this through the energy monitoring software: portal and app.
