Wɔ battery management systems (BMS) mu no, asiane ahorow 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 anyinam ahoɔden a ɛhaw adwene yi yɛ adwuma te sɛ awudifo a wɔyɛ komm, na ɛtew batere nkwa nna so na ɛde ahotoso a ɛwɔ ahoɔden nhyehyɛe a ɛho hia a wɔde sie wɔ data centers, substations, ne telecom sites no to asiane mu.
Ɛsɛ sɛ battery a eye sen biara charging ne discharging nhyehyɛe yɛ smooth DC ahoɔden. Nanso, esiane frequency a ɛkɔ soro a ɛsakra wɔ charger ne UPS nhyehyɛe ahorow mu nti, AC afã horow a wɔmpɛ no pue:
Ripple Current – AC fã bi a wɔde ahyɛ DC current no so, ɛsakrasakra ne adesoa ne charge/discharge cycles.
Ripple Voltage – AC nsakraeɛ a wɔde ahyɛ DC voltage no so, a wɔsusu no wɔ peak-to-peak anaa RMS values mu.
Saa asorɔkye yi taa ba wɔ 50Hz – 1kHz kwan so na ɛwom sɛ wontumi nhu de, nanso ɛwɔ hɔ wɔ charge cycle biara mu.
Wɔ battery monitoring system biara fam no, ripple a wobu ani gu so no yɛ asiane. Bere kɔ so no, ripple sɛe ade a wontumi nsakra:
Accelerated Plate Corrosion – Ripple current de nneɛma a ɛyɛ adwuma no hwie gu, na ɛtew ɔsom nkwa nna so.
Ɔhyew a Ɛboro So – Ripple ma ahoɔden a ɛko tia ne ɔhyew a ɛba no yɛ kɛse; 10°C biara a ɛkɔ soro no ma nnuru a ɛyɛ adwuma no yɛ mmɔho abien, na ɛma electrolyte no yɛ hyew ntɛmntɛm.
Tumi a Wɔhwere – Bere tenten ripple exposure ma tumi a etu mpɔn so tew 30–50%, sɛe battery akwahosan sohwɛ ne nhyehyɛe ahotoso.
Nea Enti a Standard Battery BMS Systems Nnɔɔso?
Battery BMS ano aduru dodow no ara susuw static parameters te sɛ voltage ne current nkutoo, na wobu wɔn ani gu ripple effects so. Eyi te sɛ nipadua mu hyew a wobɛhwɛ nanso wobu w’ani gu mogya mmoroso a ɛsakra so — akwahosan ho nsɛnkyerɛnne a ɛho hia no yera.
Ɛno nti na ɛsɛ sɛ batere a wɔde hwɛ nneɛma so nhyehyɛe a ɛkɔ akyiri ka ripple monitoring a wɔatu ho ama ho na ama wɔahwɛ ahu sɛ wobetumi de wɔn ho ato so ankasa.
Sɛ wiase nyinaa de battery management systems ma no, DFUN de PBMS9000 Series a wɔayɛ ama data center akɛseɛ, substations, ne infrastructure a ɛho hia titire ma. Ɛkɔ akyiri sen atetesɛm mu nhwehwɛmu a ɛkɔ anim a ɛma wohu asorɔkye:

Wɔ nnwuma a ɛkorɔn a wɔne Google data centers ne wiase nyinaa data center nnwumakuw anum a ɛwɔ soro afoforo ayɛ mu no, PBMS9000 series no ada ne bo adi.
Wɔ amanaman ntam data center bi mu no, PBMS9000 huu ripple abnormalities asram 6 ansa na ɛreba, na amma UPS no antwa kɛse.
