Activation Voltage is the voltage at which a charge controller will intervene to safeguard batteries. At this voltage, a charge controller transmits electrical current by permitting particular sorts of ions to pass through the membrane to safeguard the batteries is known as voltage.

Why Activation Voltage Safeguards the Battery?

The Nernst Equation’s description of battery voltage and battery capacity makes the assumption that the battery is in equilibrium. The measured voltage and battery capacity may deviate greatly from the equilibrium values because a battery under load is not in equilibrium. The further from equilibrium (i.e., the higher the charge or discharge currents), the greater the deviation between the equilibrium battery voltage and capacity may be. Polarization is the term used to describe the difference between the voltage at equilibrium and the voltage with a current flow.

Battery operation is significantly impacted by polarisation effects, both positively and negatively. For instance, polarization effects allow lead acid batteries to operate normally even when water electrolysis occurs slowly and to first order during discharge (but not charging since the voltage is higher). Polarization effects, however, also have negative consequences on performance, such as decreasing efficiency and making the battery capacity vulnerable to charging and discharging conditions. Activation voltage prevents by safeguarding the battery from working.
