        "summary": "Leaving an electric vehicle battery in a discharged state can risk over-discharge and high-voltage cell imbalance, potentially causing damage and costly repairs. Experts emphasise maintaining the State of Charge above around 20 percent for normal use to preserve battery health and longevity.",
        "content": "<p>A battery is a core component of an electric vehicle, determining\nperformance and range. Therefore, keeping the battery within a safe\ncharging level is essential. One condition to avoid is leaving an\nelectric vehicle battery in a discharged or near-empty state for an\nextended period. Budi Darmawan Jantania, Vice Country Director of the\nChery Business Unit at PT Chery Sales Indonesia, said this can pose\nrisks to the high-voltage battery system. \u2018If the electric vehicle\nbattery is left too long in a discharged state, there is a risk of\nover-discharge. This condition can trigger imbalance among cells within\nthe high-voltage battery,\u2019 he told Kompas.com on Wednesday 4 March 2026.\nIn the worst-case scenario, damage to the high-voltage battery system\ncould occur, potentially requiring intensive repairs or even replacement\nof the battery unit. \u2018Therefore, keeping the State of Charge (SOC)\nwithin a safe range is crucial to maintain the health and lifespan of\nthe electric vehicle\u2019s battery,\u2019 he said. Arif Nugroho, Service Manager\nat Hyundai Kalijaga Cirebon, concurred. He explained that if an electric\nvehicle battery is left flat for too long, it can lead to deep\ndischarge. \u2018If deep discharge occurs, the Battery Management System\n(BMS) may lock the system as a protective measure,\u2019 he noted. In more\nextreme cases, deep discharge can cause permanent degradation of the\nlithium-ion cells inside the battery. If this happens, the vehicle\ntypically requires a special recovery procedure conducted at an\nauthorised workshop. \u2018Therefore, it is very important to keep SOC above\n20 percent for normal use,\u2019 he added. By keeping the battery level\nwithin a safe range, the performance and lifespan of an electric\nvehicle\u2019s battery can be maintained more optimally.<\/p>",
