Why is the actual cruising range of electric bicycles always lower than the official data?
Electric bicycles have abandoned bulky and low-efficiency lead-acid batteries and adopted high-efficiency and lighter lithium batteries, especially now that safer lithium iron phosphate batteries are used. Therefore, the market for electric bicycles has been booming in recent years. But when people buy electric bicycles, they are usually told official data, such as how many kilometers they can walk with full power, but in fact, people feel that it is impossible to achieve such a high mileage in practice.
why is that?
Official data have prerequisites and are ideal data based on certain prerequisites, such as the default road is flat, no load, uniform speed, etc. The actual mileage is affected by many factors, such as wrong charging method, frequent braking and overloading, continuous climbing, excessive acceleration, etc.
How to make the actual cruising range reach the ideal state?
It is very important to develop good charging and riding habits: charging and not charging, at a constant speed, reasonable load, and accurately grasp the timing of acceleration and braking.
In addition, the mileage of an electric vehicle is related to many factors: motor power, controller power, tires, vehicle weight, road conditions, and riding conditions. It is recommended to remove some unnecessary functional configurations, especially lighting and audio equipment that consume a lot of power. When riding, avoid high-power discharge all the time, moderately adjust the driving speed, and maintain your battery and body parts.
Why is the electric vehicle battery just over one year, the cruising range will be reduced by half?
In addition, you can confirm whether there are problems with the electric bicycle from the following aspects:
1. Inconsistent batteries
Although the lifespan of lithium batteries is much longer than that of lead-acid batteries, in the complex actual use process, battery consistency problems may arise due to various reasons.
2. Electric vehicle motor enters water or the vehicle leaks electricity
During the use of an electric vehicle, water may enter the motor. If the motor rusts inside, the resistance of the magnet and rotor will increase during operation, which will greatly reduce the cruising range. The simple judgment is during driving. Check whether the temperature of the motor is abnormal.
3. There is a short circuit in the battery cable
This kind of situation is very common, because the battery cable is broken and then tied to the iron sheet of the battery box, which will cause a short circuit, which will cause a serious drop in battery power or battery damage.
4. The problem with the charger
The charger is irregular or its performance is degraded, and the voltage or current does not reach the nominal voltage and current value of the battery.
5. Virtual connection of battery line
If the connection of the battery is not securely connected or loosened later, problems such as inability to fully charge or become hot during use will occur, and the battery life will be greatly shortened. This situation is also common.
Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries, and are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.
