FAQ

I. After opening the electric door lock, the instrument is not displayed. Why does the vehicle not start?

1. Check whether the fuse is burned out (Solving method: replace it with a fuse of the same specification)

2. Check whether the battery wiring has fallen off (Solving method: fasten the battery cable)

3. Before checking or replacing the fuse, rotate the power switch to the power outage to prevent a sudden short circuit.

If the fuse is burned frequently, please send it to AFTER-SALES service at OFERO designated specialty stores for repair.

II. After turning on the engine, why does the vehicle not start even though the instrument is displayed?

1. Check whether the fuse is burned out (Solving method: change the same specification insurance tube)

2. Check whether the battery level is too low. (Solving method: Charge the battery)

3. Check whether the brake handlebar is back in place. (Solving method: The brake handlebar is back in place. Sometimes the brake handlebar has returned to the position, but the power-off switch connector inside will take a moment to return to the position)

4. Check whether the speed regulating line is loose or the circuit wiring failure (Solving method: Please send it to AFTER-sales service at OFERO designated specialty stores for overhaul)

III. What is the reason the vehicle cannot be charged?

1. Check whether the charger or battery fuse has burned out, what causing the charger not charging (Solving method: replace the fuse or replace the charger)

2. Check whether the battery pack wires are loose or the charging socket got damaged, causing the charger not working (Solving method: reconnect the wiring and replace the charging socket)

3. The internal components of the charger fall off, causing the charger to not charge (Solving method: replace the charger with a new one)

4. The battery is bulging, causing the charger to not charge (Solving method: replace the battery with a new one)

IV. When the outdoor temperature is low, does it affect the driving of the vehicle?

When the temperature is low, the internal chemical activity of the battery will decrease, and the corresponding capacity will also be reduced. Therefore, the lower the temperature, the shorter the mileage. In some cases, it may not even start up.

V. What do you need to pay attention to when you don't use the vehicle for a long time?

The battery is connected to internal electrical parts that will consume electrical energy. If the vehicle is not being used for a long time, the battery capacity will be exhausted until the battery feed does not work properly, seriously affecting the battery life. It is recommended to turn it off when not in use. Air switch; check and charge once a month. In addition, if the vehicle is not used for a long time, the tire pressure will be reduced, making it impossible to drive normally.

VI. What kind of battery is used for electric vehicles, how long does it take to charge, and how long is the battery life?

Batteries are divided into lead-acid batteries and lithium batteries; lead-acid batteries usually take 8-10 hours, and lithium batteries take 7-8 hours to fully charge; the cycle life of lead-acid batteries is usually 200-600, and the cycle life of lithium batteries is generally 500-1100.

VII. Compared with traditional lead-acid batteries, what are the new materials used in graphene batteries? Is it harmful to the environment?

Graphite materials are extracted from minerals and are environmentally friendly.
