Always check the circuit plug-in points of the electric bicycle. Prevent the contact point from sparking and heating due to infirm contact. Avoid the occurrence of short circuit and series electric accidents caused by the aging and wear of the line. In the course of normal use of electric vehicles, professional maintenance organizations or personnel should be selected for failures. Do not disassemble the electrical protection device without authorization. Ensure that the electrical wiring and protection devices are intact and effective.

When the battery of an electric bicycle is charged, flammable gas escapes. Therefore, the charging must not be in a narrow, sealed environment. It should be done outdoors as far as possible, or the battery should be removed and charged separately. When charging, choose the appropriate line. The wiring should be fixedly installed, and short-circuit and leakage protection devices should be installed.

The charging of electric vehicles must be far away from flammable materials, and the charging time must not be too long. If the charging time is too long, overheating of the charger may cause fire hazards. When charging, it should be charged in accordance with the instructions in the manual, and the charging time should not exceed 10 hours in principle. When charging, place the charger in a place where it is easier to dissipate heat. If the battery of an electric bicycle is of poor quality or is used for a long time, the temperature of the charger is likely to be very high, causing a fire. So charging during the night sleep time should not be taken lightly.
