Wɔ battery management systems (BMS) mu no, asiane a wobu ani gu so kɛse ma lead-acid ne NI-CD battery no mu biako ne ripple current ne ripple voltage. Ɛwom sɛ mpɛn pii no wontumi nhu de, nanso saa anyinam ahoɔden basabasayɛ yi yɛ adwuma te sɛ awudifo a wɔyɛ komm, na ɛma batere no nkwa nna so tew na ɛde ahotoso a ɛwɔ tumi a ɛho hia a wɔde gyina akyi wɔ data mmeae, substations, ne telecom mmeae ahorow no to asiane mu.
Ɛsɛ sɛ battery bi charging ne discharging nhyehyɛe a eye no yɛ DC ahoɔden a ɛyɛ mmerɛw. Nanso, esiane frequency a ɛkɔ soro a ɛsakra wɔ charger ne UPS nhyehyɛe mu nti, AC afã horow a wɔmpɛ no pue:

Wɔ batere sohwɛ nhyehyɛe biara ho no, Ripple a wobebu wɔn ani agu so no yɛ asiane. Bere kɔ so no, Ripple de ɔsɛe a wontumi nsakra no ba:
Accelerated plate corrosion – Ripple current ma nneɛma a ɛyɛ adwuma no hwie gu, na ɛtew ɔsom nkwa so.
