How to Safely Use Fast Charging for Electric Vehicles

Jakarta - The use of fast charging in electric vehicles is increasingly common, particularly for daily mobility and long-distance travel. However, many electric vehicle users remain concerned that frequent fast charging may reduce battery lifespan. Jaecoo’s Aftersales Service Operations Manager Bayu AgusMustofa said fast charging is safe when done correctly. ‘This depends on daily usage. For high mobility, it’s recommended to limit fast charging to a maximum of 80%,’ he said in North Jakarta on Sunday, 24 May 2026. He explained that limiting fast charging to around 80% helps maintain optimal battery condition, especially for vehicles used intensively every day. The vehicle’s battery temperature also needs to be monitored during charging. ‘Vehicle temperature must be considered, and a monthly calibration to 100% may be necessary,’ Bayu added. Battery calibration helps the system read capacity more accurately, but Bayu advised using slow charging at home for this process. Fast charging enables electric vehicle batteries to be charged much faster than conventional charging. However, the process typically generates higher temperatures, so users are advised to monitor charging habits to preserve battery health over the long term. Currently, most modern electric vehicles are equipped with a BatteryManagement System (BMS) to regulate temperature and electrical current during charging.
