Temperature affect The life of lead acid battery of China electric bike increases with the increase of temperature. At 10-35 ¡æ, for each increase of 1 ¡æ, about 5-6 cycles are added. Between 35-45 ¡æ, each increase of 1 ¡æ can prolong the life span by more than 25 cycles. When the temperature is higher…

The failure of lead-acid battery of China electric bike is the result of many factors, which is determined by the internal factors of the plate. Such as composition of active substances, crystal form, porosity, plate size, grid material and structure, etc. It also depends on a series of external factors, such as discharge current density,…

Luxury electric cars now run at speeds as high as 35 km / h. The phenomenal development of luxury China electric bike from their birth to their subsequent development, and their market share, clearly tell us how much the market accepts and likes it. With the increase of bike speed, the constant current of electric…

China electric bike batteries are favored by electric bike manufacturers and users due to their unique advantages of low price, less maintenance, easy replacement and so on. However, in the process of its use there are some problems, resulting in frequent complaints about batteries used in electric bike. These problems arise mainly from: Improper use…

Whether brushless motor or brushless motor, it is normal to produce some mechanical noise (brushless) or electric magnetic resonance (EMR) during operation. However, if the brushless motor produces abnormal vibration and sound during operation, the power lock should be shut off and overhauled in time. When the electric dirt bike moves backwards, it is normal…

First of all, like the maintenance of ordinary bicycles, the front axle, center shaft, flywheel, chain and other transmission parts of the electric dirt bike should be inspected regularly, wiped and lubricated to prevent the normal use due to rust. The motor does not need to scrub and lubricate itself, but only to the repair…

Fault phenomenon First, let's look at the standard case where the battery voltage drops too fast: put a new battery on an electric mountain bike, and as soon as it moves together, the voltage of the electric car drops very fast. Failure check and treatment of battery voltage drop too fast Check that the display…

If your electric mountain bike has leakage, do the appearance check first, find out the leakage of acid leakage; Then take the lid off to see the impermeable acid leak around the cap valve, and then open the cap valve to observe the flow of electrolyte inside the battery. After the above work has been…

Do not change the charger at will. Use the charger correctly according to the instructions. Before charging, make sure that the charger plug (positive and negative electrode) matches the battery socket of the whole car. It is forbidden to use non-standard and inferior charger to charge the battery so as not to cause unnecessary damage…

The gas in the electric mountain bike tyre is reduced or exhausted in 2-3 days, which is called the chronic air leakage of the tires. Specific failures and troubleshooting methods can be found in the following four points: Failure cause: valve tube rupture or valve tube due to aging soft. Elimination: screw out the pressure…

As a new type of vehicle, electric dirt bike is favored by more and more friends because of the characteristics of environmental protection and energy saving. But a better electric dirt bike is generally not too cheap. Battery is important electric dirt bike. So it's important for most friends to use and maintain an electric…

The chain often falls off the flywheel or sprocket during the normal cycle of an electric mountain bike. This failure is called the drop of the chain If the rear wheel is no longer in position and the chain is still loose, the chain should be cut short and then adjusted. The sprocket, chain and…

Whether brushless motor or brushless motor, it is normal to produce some mechanical noise (brushless) or foldable electric bike during operation. However, if the brushless motor produces abnormal vibration and sound during operation, the power lock should be shut off and overhauled in time. When the electric vehicle moves backwards, it is normal to feel…

The electric vehicle controller is the core controller used to control the starting, running, moving, moving, speed, stopping and other electronic devices of the foldable electric bike. The electric vehicle consists of two parts: software part and hardware part. There are many kinds of electric vehicle controllers in the two parts of adjustment and different…

At present, the electric bicycle which can be seen in the market can be divided into: rare earth permanent magnet brushless motor, rare earth permanent magnet brushless DC motor, rare earth permanent magnet brushless DC motor, foldable electric bike. In the actual production process, because the toothed DC motor is a high-speed motor, the teeth…

Reason 1: adjust handle and photosensitive film, photosensitive tube to store dirt Treatment: clean or replace the photosensitive film to wipe the photosensitive tube Cause 2: local damage of components in speed control handle Treatment: replacement of speed control handle Reason 3: the battery is insufficient, full or unpowered Treatment methods: refer to the causes…

1, the battery of electric bicycle is not enough, charge the battery. 2, battery contact bad, adjust contact position or polish contact. Bad contact between the safety tube and the seat in the battery box, adjust or replace it to make it good. The speed regulation hand handle inside the photosensitive film sensitive tube has…

Check that the battery output of the electric bike is normal. If the output is too low to prove that the battery is out of order, it is urgent to replace the battery. Check the switch. A positive pole and signal line with a short wire switch which, if the car can turn, proves that…
