About Voltti Kikowaena Hoʻopiha Kalaka Kaʻa Uila

ʻO Voltti kahi kikowaena hoʻopiha kalaka kaʻa uila i hoʻolālāʻia no nā kaiapuni kūlanakauhale. Ua ana ʻia ke kikowaena ma 800 mm ka laulā, 400 mm ka hohonu, a me 1800 mm ke kiʻekiʻe, e hāʻawi ana i kahi ʻano liʻiliʻi. Mālama kahi pahu uila ʻoniʻoni paʻa (solid-state battery) 100 kWh i ka ikehu a kākoʻo i ka hoʻopiha wikiwiki DC 150 kW ʻoiai e hoʻohaʻahaʻa ana i ka koi ma luna o ka ʻoihana uila. Hoʻoponopono ka polokalamu hoʻokele mana i ka hoʻopuka e like me ke kūlana o ka pahu uila a me ke kaumaha o ka ʻoihana uila. Hoʻomaka ʻia ka hoʻopiha ma ka hoʻopili ʻana i kahi kaʻa, a hiki ke nānā ʻia ma o kahi hōʻike pā hoʻopā a i ʻole kahi polokalamu kelepona paʻa lima. Hana ʻia ka ʻaoʻao waho me nā mea hui māmā a me kahi uhi kūpaʻa i ke aniau.
