At present, my country's electric bicycle has exceeded 250 million, with an annual output and sales of more than 30,000 (annual output of 45 million). In the second and third-tier cities, electric bicycles are already the main force of short distance travel. At present, according to the latest national standards GB17761-2018, there is almost 200 million vehicles that are not compliant.
The period given by the elimination of the super-standard car is basically 2 to 3 years, which means that there is a considerable proportion of users in the next 2 to 3 years, they will purchase super-standard cars due to price advantage. However, in addition to the battery weight exceeds the battery weight, the battery is not durable is also a problem that the electric bicycle user is still plagued; most of these excellent electric bicycles use lead-acid batteries, if as the main travel tool, basically two months later The endless mileage begins to shrink. Of course, in addition to the factors of the lead-acid battery itself, some daily equipment losses and improper habits can also lead to the decline in electric vehicle life.
In order to profit workers, electric bicycle manufacturers are either poorly poor magnetic steel, or reduce the number of magnetic steel sheets; low-speed peace path may still be reflected, one but acceleration or uphill appear special feet; The power power will fall, and it is natural to charge. In addition, long-term use of electric bicycles (more than 2 to 3 years), will also resolve this problem with motor magnetic steel due to the normal aging of magnetic steel. In order to reduce costs, the charger will purchase a batch of bare cars from the small manufacturer (not including battery and charger), sometimes for the maximum profit, the dealer will match the electric bicycle with inferior charger, and inferior charger It will cause a big damage to the battery, resulting in acceleration of battery life.
The quality charger uses brand components, high temperature resistance, and vibration will not fall off. Inferior chargers are often artificial plug-ins, not high temperature, and through strong vibration will accelerate, leading to battery charge, even overcharge. From the material, the quality charger will be made of pure copper, and the conductive performance is better and more stable.
Inferior chargers are often copper-clad aluminum, not only poor conductivity, but also unstable, it will cause insufficient charging or overturizing. High quality chargers will use national label pure copper wire, not easy to fever, will not burn bad. Inferior chargers are often ordinary wires, not only easy to heat, if the temperature is too high, it is easy to be burnt.
From the welding process, both quality chargers use the wave welding, not only make the charger's stability, but will not short-circuit the charger. And inferior chargers tend to weld the welding process, and it is easy to short circuit. Finally, pay attention to the model and parameter of the charger must match the battery, otherwise it will cause damage to the battery.
The tire pressure tire pressure is too low, which not only affects driving safety, but also accelerates power consumption due to the increase of the resistance of the tire and the ground. The tire pressure is too high, which will cause the carcass to be over, fatigue, the tire shell is easy to rupture and cut, resulting in shorting of tire life. General electric car bicycle pressure is: 200kp (ie 2.
0 atmospheric pressure); general summer can be slightly lower, winter can be played more. General users don't buy a special test pressure tool because electric cars, therefore uses the hand pressure. Specific method: I feel laborious when I use bicycle air gun, and the gas tube can't press it.
It is basically possible; or after the gas is finished, the tire is basically not deformable. The brakes and tire pressure are too low, and the brakes are too tightly caused to increase the resistance and cause continuous shrinkage. Since the electric bicycle driving power is driven by the motor, the overtight of the brake adjustment is not easy to detect in riding, which will increase the battery output current to damage the battery.
Line battery connection line is too thin, easy to loosen, corrosion, and often exposure and rain led to aging. It is recommended to check the line at least one year. If aging is aging, it should be replaced in time, not replacement, not only makes battery power consumption.
, There will be dangerous electric bicycle spontaneous combustion. Driving a long distance climbing, load, overload, and electric bicycle frequent acceleration and starting can cause electric bicycles to consume quick power, cycling, should still be uniform. In addition, in low temperature environments, whether the lead-acid battery or lithium-ion battery will have a certain impact on.
