SOC-Steuerungsmethode für Energiespeicherbatterien

Was ist der Unterschied zwischen SOC 1, SOC 2 und SOC 3 und daraus resultierend, welcher SOC-Report ist für wen sinnvoll? SOC steht für engl. „System and Organization Controls" und stellt in den Varianten SOC 1,

What is SOC in a battery control system?

In a battery control system, the state of charge is like the fuel gauge in a normal car. The SOC job is to tell the driver how the battery is doing and keep problems like overcharging and over-discharging from happening [12, 13]. In fact, figuring out how to estimate the SOC is a problem that has been studied.

Why is the SOC of a battery important?

As stated at the beginning, the SOC of the battery is also a crucial part of BMS. When the SOC of a battery is precisely and safely estimated, it can be used as a measurement factor for automotive energy management and the best design of the control system.

How do you calculate SOC of a battery?

Coulomb Counting Method The coulomb counting method is the easiest way to figure out the SOC of a battery. This method is employed to calculate the SOC (t). The SOC (t − 1) values that were estimated before are used to figure out the SOC (t).

What is SOC in electric cars?

The SOC of a battery is the ratio of how much power is still left in the battery to how much power is available in certain scenarios (discharge and charge ratio, temperature) . In electric cars, an important parameter is the State of Charge (SOC), which shows the current storage capacity as a percentage of the total potential.

How to evaluate SOC of a battery using computational intelligence?

Lee et al. looked into a way to evaluate the SOC of each battery in a series of batteries using computational intelligence. A FNN, B-splint membership functions, and a reduced-form genetic algorithm are all used together in computational intelligence . The SOC estimation techniques are listed in Table 2 along with their merits and demerits.

What does SoC mean in chemistry?

SOC may be written as [0, 50 and 100%] or [0, 0.5 and 1]. A cell with a SOC of 100% or 1 is completely charged. A cell with a SOC of 50% or 0.5 is half charged or half discharged. A cell with a SOC of 0% or 0 is empty . Figure 4 depicts the SOC (in %) value during charging and discharging. In Fig. 4 OCV is the open-circuit voltage of the cell.
