Liiglaadimise

Liiglaadimise, often translated as "overcharging" or "overloading," refers to the act of subjecting a battery to a voltage or current that exceeds its designed safe operating limits. This can occur during the charging process, where a charger supplies more power than the battery can safely absorb. Conversely, it can also happen during discharge if the battery is subjected to a load that draws current beyond its capacity.

The consequences of liiglaadimise can vary depending on the battery chemistry and the severity of the overcharge. For many rechargeable battery types, such as lithium-ion, overcharging can lead to a buildup of heat, accelerating degradation of internal components. In extreme cases, this heat can cause thermal runaway, a dangerous condition where the battery's temperature increases uncontrollably, potentially leading to swelling, venting of flammable gases, or even fire.

Liiglaadimise can also permanently reduce a battery's capacity and lifespan. Repeated or severe overcharging can damage the electrode materials and electrolyte, diminishing the battery's ability to store and deliver energy efficiently. To prevent liiglaadimise, modern charging systems incorporate sophisticated battery management systems (BMS) that monitor voltage, current, and temperature, and automatically terminate the charging process when safe limits are reached. Users should always use chargers specifically designed for their battery type and capacity to ensure safe and optimal operation.
