Stav nabit\u00ed (State of Charge-SOC) je jeden z t\u011bch klamav\u011b jednoduch\u00fdch term\u00edn\u016f, kter\u00e9 v\u0161ichni v oblasti bateri\u00ed pou\u017e\u00edvaj\u00ed, jako by to byl zdrav\u00fd rozum.

Podstatou SOC je zb\u00fdvaj\u00edc\u00ed kapacita<\/em> baterie ve srovn\u00e1n\u00ed s jej\u00ed plnou kapacitou.

Co znamen\u00e1 stav nabit\u00ed (SOC) u bateri\u00ed?<\/h3>

SOC je nejjednodu\u0161eji \u0159e\u010deno pom\u011br aktu\u00e1ln\u00edho nabit\u00ed baterie k jej\u00ed maxim\u00e1ln\u00ed nab\u00edjec\u00ed kapacit\u011b. P\u0159edstavte si baterii jako n\u00e1dr\u017e s benz\u00ednem. SOC v\u00e1m \u0159\u00edk\u00e1, jak je n\u00e1dr\u017e pln\u00e1 pr\u00e1v\u011b te\u010f<\/em>. Pokud m\u00e1 va\u0161e baterie v elektromobilu maxim\u00e1ln\u00ed kapacitu 100 kWh a vy m\u00e1te aktu\u00e1ln\u011b ulo\u017eeno 50 kWh, je v\u00e1\u0161 SOC 50%.<\/p>

Ale nen\u00ed to tak jednoduch\u00e9. Baterie nejsou dokonal\u00e9 n\u00e1dr\u017ee. Degraduj\u00ed, m\u011bn\u00ed se jejich chemick\u00e9 slo\u017een\u00ed a podm\u00ednky prost\u0159ed\u00ed m\u011bn\u00ed, co znamen\u00e1 \"pln\u00e1\".<\/p>

Vzpome\u0148te si na ikonu baterie smartphonu. Kdy\u017e je na n\u00ed naps\u00e1no 80%, neznamen\u00e1 to u\u017e p\u0159esn\u011b 80% p\u016fvodn\u00ed v\u00fdrobn\u00ed kapacity, zejm\u00e9na pokud je va\u0161e baterie n\u011bkolik let star\u00e1. To je z\u00e1sadn\u00ed rozd\u00edl - SO\u010c m\u011b\u0159\u00ed. aktu\u00e1ln\u00ed<\/em> stav vzhledem k aktu\u00e1ln\u00ed<\/em> kapacita, kter\u00e1 se m\u011bn\u00ed v z\u00e1vislosti na st\u00e1\u0159\u00ed a stavu baterie.<\/p>
