6. Controlling depth of discharge
If the battery reaches 95% on any day, the dynamic discharge limit is lowered by 5%. The result is that the battery reaches a healthy charge of between
In more detail, let's look at the critical components of a battery energy storage system (BESS). The battery is a crucial component within the BESS; it stores the energy ready to be dispatched when needed. A battery contains lithium cells arranged in series and parallel to form modules, which stack into racks.
The charger will ensure that voltage level is maintained - using power from the grid when necessary. The maximum charge current it uses for this is 5 Ampére per unit. (5 A applies to all installations - regardless of system voltages (12 / 24 / 48 V). Excess solar power will also be used for battery charging.
The charging and discharging speed of a BESS is denoted by its C-rate, which relates the current to the battery's capacity. The C-rate is a critical factor influencing how quickly a battery can be charged or discharged without compromising its performance or lifespan.
State of Charge (SOC): Real-Time Energy Monitoring SOC represents the percentage of remaining charge in a battery. Accurate SOC monitoring ensures optimal charge-discharge management, preventing issues like overcharging and deep discharge, which can degrade battery health over time.
