Driver law malawng gaw, regenerative braking hpe lawan ladan hkap la nna, htunghking braking hta grau nna htuk manu ai hte hkang lu ai mahkrum madup hpe mu lu ma ai. Brake dive n nga ai-htung tara hku brake galaw ai shaloi byin pru wa ai shawng de na nsen- gaw deceleration hpe grau shim lum ai hku hkam sha shangun ai. Ndai atsam marai ni hpe gram lajang ra ai lam hpe shayawm ya ai hte n-gun jat ya ai lam ni hte hpawn, wan jak mawdaw ni a manu shadan dik ai atsam marai langai mi hpe bai gram lajang ai braking byin shangun ai.

Wan jak mawdaw ni hpe jai lang ai lam lawan wa ai hte maren, ndai hpaji masa gaw matut nna rawt jat wa nga ai. Battery chemistry grau kaja ai, grau kaja ai motor ni, grau hpaji rawng ai hku hkang ai algorithm ni gaw, bai gram lajang ai braking atsam hpe grau tsaw hkra shadut ya nga ai. Asan sha n-gun bai lu la ai ladat hku nna hpang wa ai gaw, mawdaw brake hte n-gun hpe hparan ai lam hpe anhte gara hku myit ai hpe madung hku nna galai shai shangun ai, grai kungkyang ai hpaji masa langai byin wa sai.
