Cell Balancing

Battery hpaji rawt jat wa ai hte maren, dai ginra gaw matut nna rawt jat wa nga ai:

Solid-state battery ni: Solid-state lithium battery ni hpe hpaga lam de du wa ai shaloi, shanhte a n bung ai wan n-gun atsam ni gaw, n-gun n bung ai ladat nnan ni ra na re. Liquid electrolyte n nga ai gaw hkrat sum ai lam ni hte asak kaba wa ai lam ni hpe galai shai shangun ai.

Wireless balancing: Hpaji sawk sagawn ai lam ni gaw, wan n-gun n lawm ai cell ni a lapran na capacitive (sh) inductive power transfer hpe sawk sagawn ai, pack design hpe asan sha galaw ya lu ai hte wiring a yak hkak ai lam hpe shayawm ya lu ai.
