  "textContent": "A cell balancing control method in a dual battery system and a system thereof are provided. The cell balancing control method in a dual battery system uses a sub high voltage battery for stably extending a driving distance in an electric vehicle and may perform cell balancing of a main high voltage battery by using the sub high voltage battery even if there is no separate slow charger in the dual battery system, thereby extending the life of a battery since a current can evenly spread and solidly have energy density when the main high voltage battery is fully charged by slow charging.",
