Wireless charging bubu ɔkwan a tumi a wɔde fa so no betumi de ne ho ato nhama a wɔde fa so tẽẽ so nkutoo. Ɛyɛ non{1}}akɔ nkitahodi mu na ebetumi akwati nkitahodi nkankyee, sliding wear, explosion ne electric shock a ebia ɛnam contact power transmission so na ɛde ba. Wireless tumi a wɔde fa nneɛma so no atitiriw abiɛsa na ɛwɔ hɔ: electromagnetic induction, electromagnetic resonance ne electromagnetic radiation.

Electromagnetic induction ne ɔkwan a wɔtaa fa so de wireless tumi di dwuma sen biara. Ne mfiridwuma no ayɛ mass-ayɛ, a ɛka a wɔbɔ wɔ nneɛma a wɔyɛ ho no sua sen mfiridwuma afoforo, na ɛtwam ahobammɔ ne gua so nokwaredi. Mprempren, apam akɛse abiɛsa wɔ hɔ a wɔatu wɔn ho ama sɛ wɔbɛyɛ na wɔayɛ no pɛpɛɛpɛ wɔ wireless charge mfiridwuma mu. Saa apam mmiɛnsa yi yɛ Alliance for Wireless Power (A4WP), Power Matters Alliance (PAM) ne Wireless Power Consortium (WPC). Qi gyinapɛn no yɛ "wireless charging" gyinapɛn a WPC de sii hɔ, a ɛde electromagnetic induction charging mfiridwuma titiriw di dwuma. Qi gyinapɛn no titiriw de si ɛlɛtrɔnik nneɛma a wotumi fa so te sɛ mfoninitwa mfiri, video ne nnwom a wɔbɔ, agode, ankorankoro hwɛ ne telefon a wokura kyin so. Mprempren, nhwehwɛmu ne nhyehyɛe a ɛwɔ fam-power wireless charger ahorow no yɛ nea wɔde asi mobile phone wireless charging so titiriw. Wɔn nyinaa de TI’s BQ500211 dedicated chip di dwuma. Ebinom a ɛba fam-power terminals nso de dedicated integrated chips di dwuma. Chips a wɔaka abom a wɔatu ho ama a wɔde di dwuma no betumi akora nkɔso bere so wɔ nkɔso a edi kan no mu, nanso bere tenten no ɛnyɛ nea ɛfata ma ɛka a wɔbɛtew so ne akyiri yi ntrɛwmu ne nkɔso.

Ɛwom sɛ wireless charging mfiridwuma anya nkɔso bi de, nanso mfiridwuma ho haw ahorow bi da so ara wɔ nkɔso nhyehyɛe no mu. Nea edi kan no, sɛnea charge no yɛ adwuma yiye no nyɛ kɛse.
