Mɛyɛ dɛn ahu sɛ me batere no asɛe asen nea wɔakyerɛ?

So metumi de batere ahorow afrafra wɔ nhyehyɛe koro mu?
Mfiridwuma mu no ebetumi aba nanso ɛyɛ ɔhaw wɔ adwumayɛ mu. Nnwumakuw ahorow de nkwammoaa mu nnuru, ɔhyew su, ne ahoɔden a wɔde yɛ nneɛma ahorow di dwuma. Batere ahoɔden a wɔkora so nhyehyɛe a "ɛyɛ pɛ" mpo taa nya ɔsɛe ntɛmntɛm bere a wɔadi afra esiane nkwammoaa a ɛnkari pɛ nti. Sɛ augmenting, bata mfitiase manufacturer anaa nhyehyɛe parallel ahofadi nhyehyɛe ahorow.
Sɛ me augment a, dɛn na ɛba me warranty no so?
Kenkan nkyerɛwee a ɛyɛ fɛ no. Sɛ wosakra nhyehyɛe no a nea ɔyɛe no mfa ne ho nhyɛ mu a, warranty dodow no ara yɛ kwa. Nnwumakuw binom de augmentation kits a warranty ntrɛwmu ma. Afoforo nso hwehwɛ sɛ wɔsan nya adansedi krataa bere a wɔayɛ nsakrae awie no. Ma nea ɛkyerɛ wɔ warranty ho mu da hɔ ansa na woatɔ nnwinnade foforo.
So ɛsɛ sɛ meyɛ upgrade kɔ battery chemistry a aba foforo so?
Ɛnyɛ nea ɛba ara kwa. LFP yɛ nteaseɛ ma dwumadie dodoɔ no ara ɛnam ahobanbɔ ne kyinhyia asetena mu mfasoɔ nti. Nanso sɛ wowɔ NMC batere a ɛyɛ adwuma a ɛwɔ 75% tumi na wuhia ahoɔden a ɛkɔ soro wɔ baabi a ɛyɛ kakraa bi a, ebia nnuru a ɛwɔ hɔ dedaw no a wobɛhyia no bɛyɛ nea mfaso wɔ so sen nsakrae a wobɛsakra wɔ mfinimfini-asetra mu.

Nneɛma a wɔde besi ananmu ntɛm ara gye adapɛn 12-20 esiane mfiri no bere a wɔde di dwuma nti.
So ɛfata sɛ wobɛma nhyehyɛe bi a adi mfe 5 pɛ no ayɛ foforo?
Egyina sɛnea wɔde di dwuma no mu den so. Battery a wɔde cycle pɛnkoro da biara ma peak shaving betumi abɔ 70% tumi wɔ mfe 5 mu (bɛyɛ 1,800 full cycle equivalents).
