            Battery Safety

            The battery passed a number of destructive experiments: high temperature, short circuit, squeezing, soaking, overcharge, and puncture.

            • Single body squeezing

            • Module squeezing

            • Single body puncture

            • Module puncture

            Warranty

            5-year warranty and can be extended to 8 years. Single vehicle after passed the 30,000KM comprehensive road test and battery high temperature cycle test, the battery capacity reduces less than 10%. After 5,000 times of charge-discharge, the battery capacity is not less than 75%, that is to say, the life space can last for 8 years, helps to solve your worries about battery capacity.

            Intelligent remote control, improvement of vehicle driving safety

            Real time information monitoring, including vehicle running state, battery voltage and temperature, and accurate location of vehicles, helps to ensure optimum battery status, safety of vehicle system operation, and to assist the city bus system to accomplish traffic dispatching. With functions of custom rules alarm and expert-level diagnosis
