Help in programming

I have a programming problem... I implement a model and in this model i read the SOC value to off the battery's charger when SOC>0,9... When SOC<0,9 the battery's charge. The problem is when this appened, the simulation slows because fluctuate between 0.89 and 0.91... how do I get after being greater than 0.9 only charger again when SOC=0.85 for exemple?

This is typical when you have this bang-bang like control. You can use the Relay block to implement a upper and lower limit.
