The electric bicycle is running out of power. How to solve it?

Internal reason: 1: The electric quantity display of electric vehicle is rough.

For example, 1000-2000 electric bicycle mostly adopts the load voltage method, which is not accurate, because the voltage change of the battery is not linear and stable, so in addition to the fully charged situation, sudden braking and too fast speed regulation will also cause the battery to be fully charged and the handle to be twisted off.

Solution: If this is the case, it is normal. Don't worry too much. The owner can avoid sudden braking and acceleration, and also make the service life of the car longer.

Internal cause 2: vulcanization of electric vehicle battery

Sulfurization refers to the white crystalline substance generated on the battery plate, which will affect the chemical reaction of the battery. The more crystals are formed, the shorter the charging time, the more serious the virtual electricity of electric vehicles, and the situation of "turning the handle to turn off the power supply" will be more serious.

Solution: If the battery life of electric vehicle is reduced by about 30%, the owner can solve it by adding distilled water to the exhaust hole. The principle is that less is better than more, and this method is basically free of money. But if the battery life is particularly serious, then the owner can't solve it by himself. It is recommended to listen to the advice of professionals.

Internal cause 3: Self-discharge of electric vehicle battery leads to "virtual electricity"

The battery of the electric car itself is discharged. Although there is no need, the strength is still slowly losing. The more intelligent the function, the more serious the self-discharge of electric vehicles, with an average of about 2%-5% per day. Therefore, the electric car that has been protected for a long time shows full charge when it is started, but once the handle is turned on, it will soon be dead.

Solution: Leave unused electric vehicles and charge them once every 1 cycle, or directly unplug the connecting wires between the batteries of electric vehicles. At this time, the electric vehicle has no voltage, and even if it is placed, it will not self-discharge.

External reasons: the cold weather leads to the decrease of battery activity.

This problem is mainly caused by environmental changes. Whether it is a lead-acid battery or a lithium battery, with the decrease of temperature, the storage capacity of the battery, that is, the capacity of the battery, will decrease, which directly leads to the battery that can be fully charged in 8 hours and 4 hours, but in fact it is only an illusion, and the weather is too cold, especially below 0℃, and it is easy to appear the situation of "full when the handle is opened, there is no electricity".

Solution: Try to charge in a closed charging place, extend the charging time appropriately, and avoid sudden braking and rushing when riding, which can be alleviated.
