First, avoid storing electric vehicles with a depleted battery

The longer the idle time in a discharged state, the more severe the battery damage. Therefore, when an electric vehicle is not used for an extended period, it should be fully charged, all circuits disconnected, and the leakage protector turned off. This can effectively reduce the rate of battery discharge.

Taking a 60V20Ah standard lead-acid battery used for six months as an example, if it is disconnected from the power source and left idle for half a month, even in low-temperature conditions, it can still retain nearly half of its charge upon reconnection. Without power disconnection, aside from the battery's natural self-discharge, components such as alarms in the vehicle remain powered and continue to consume electricity at a certain rate. Some smart vehicle models also have additional components like trackers and Bluetooth modules, resulting in a higher static power consumption rate.

Secondly, when charging an electric vehicle, the charging time should be controlled to around 8 hours to avoid overcharging and undercharging. Once the indicator light shows a full charge, an additional 2-3 hours of float charging is recommended. It is best to charge the battery to full capacity in one session. If riding is necessary during charging, the battery should be fully charged immediately after riding to help extend its lifespan. Additionally, ensure the battery is securely installed to prevent damage from vibrations during riding; regularly remove dust and debris to keep the battery dry and clean; and never open the battery cover without authorization to avoid potential hazards.

In daily electric vehicle usage, the maintenance of the braking system is also crucial. Worn or rusted brake pads can compromise riding safety. The correct approach is to inspect the brake pads every six months to a year to ensure optimal braking performance. Additionally, it is necessary to check the power-off brake levers, especially the left brake lever of the rear brake, as a failure in the power-off function may damage the controller during operation.

When charging an electric vehicle battery, it is advisable to keep the charge level around 30%. Frequent charging can affect the battery's lifespan, while waiting until it is fully depleted before charging may lead to over-discharging. Therefore, maintaining a charge level of approximately 30% is recommended to effectively extend the battery's lifespan.

In addition to battery maintenance, the motor and lighting system also require attention. Water ingress and demagnetization of the motor can affect the performance of the electric vehicle. Motor water ingress is usually caused by external force deforming the hub, while motor demagnetization occurs when the electric vehicle is exposed to direct sunlight.

Once the motor demagnetizes, the power of the electric vehicle will decline inadequately, and severe cases may require motor replacement. The lighting system of the electric vehicle also needs attention. If the headlights or turn signals fail to illuminate, it could indicate a short circuit issue. The wiring should be inspected, and waterproof tape should be applied at the junction points to prevent further short circuits. If the cause remains unclear, it is advisable to seek assistance from a mechanic and ensure proper waterproofing measures are taken.

In summary, electric vehicles require battery maintenance, charging, brake inspection, and routine upkeep after prolonged storage to ensure proper operation.
