Connect one end of the voltage booster to your device’s power outlet and switch it on. The booster should then provide extra power to push start your battery, allowing you to use your device again. Monitor the voltage levels, as too much power, can damage your device.

Avviamento con alimentazione esterna

Infine, se nessuno dei metodi precedenti funziona, si può pensare di far ripartire la batteria al litio scarica utilizzando un alimentatore esterno. Un alimentatore esterno è essenzialmente come collegare il dispositivo direttamente a una presa di corrente senza utilizzare le batterie o i caricabatterie interni; tuttavia, questa operazione potrebbe causare danni se non viene eseguita correttamente, quindi è necessario prestare attenzione quando si tenta questo metodo.

Come avviare una batteria agli ioni di litio scarica?

L'avviamento di una batteria agli ioni di litio può essere complicato a causa della necessità di monitorare attentamente il processo di carica. Tuttavia, con le conoscenze e gli strumenti adeguati, è possibile riattivare una batteria scarica in modo sicuro.

Determinare la tensione della batteria

Il primo passo per avviare una batteria agli ioni di litio è determinare il suo livello di tensione. A temperatura ambiente, il livello di carica ideale dovrebbe essere compreso tra 3,6 e 4,2 volt per cella. Se la tensione è superiore o inferiore a questo intervallo, è probabile che la batteria sia stata danneggiata rispettivamente da un sovraccarico o da un sottocarico e che richieda quindi un intervento professionale prima di essere ricaricata.

Selezionare un caricatore appropriato

Una volta determinata la tensione, è necessario scegliere un caricabatterie appropriato per non danneggiare ulteriormente la batteria durante la ricarica. Per la maggior parte delle batterie standard agli ioni di litio è opportuno utilizzare un caricabatterie a corrente costante/tensione costante (CC/CV).

Aumentare gradualmente la tensione di carica

Il caricabatterie CC/CV aumenta lentamente la corrente fino a raggiungere la velocità di carica massima consentita per lo specifico modello di batteria. Dopo questo punto, mantiene la corrente aumentando gradualmente la tensione fino al raggiungimento della capacità totale.

Monitoraggio del processo di carica

While charging, it’s essential to closely monitor the current and voltage levels, as an improper balance could lead to increased damage on either account. Once full charge is reached, further monitoring should take place to ensure no overcharge occurs, as this can reduce the overall performance of the battery in addition to shortening its lifespan significantly if repeatedly done enough times over time.

Come prevenire i futuri guasti delle batterie agli ioni di litio?

Per garantire la durata e la sicurezza delle batterie agli ioni di litio utilizzate in vari dispositivi, dall'elettronica in miniatura ai grandi veicoli elettrici, è fondamentale adottare misure per prevenire potenziali guasti.
