Electric bicycles have gradually become one of the important means of transportation for urban travel. Electric bicycle batteries are the main source of power for electric vehicles.
At present, the power batteries used in electric bicycles are generally divided into two types, lead-acid batteries and lithium-ion batteries. The main advantages of lead-acid batteries are low cost, safety and stability, and good high current discharge and high and low temperature discharge performance. The advantages of lithium-ion batteries are high energy density, lighter than lead-acid batteries, longer service life, shorter charging time, and more in line with consumers’ demand for fast charging. Therefore, lithium batteries have been more widely used in the field of electric bicycles.
How to buy lithium batteries for electric bicycles?
When consumers buy lithium-ion batteries for electric bicycles, they can focus on the following three aspects
1. Purchase through formal channels. When purchasing electric bicycle batteries, you must purchase them through formal channels and check whether the product logos of electric bicycle batteries are complete before purchasing. First, check whether there is a manufacturer’s name, product specifications and models, nominal voltage, manufacturing date (or production batch number), and trademark; second, check whether the internal and external logos are consistent, especially to check whether the product body has eye-catching signs, precautions, and logos or nameplates.
When consumers buy electric bicycles, they should try to buy batteries together with the whole vehicle. If you need to buy batteries separately, you should buy batteries that match the electric bicycle certificate information (battery manufacturer, battery type, capacity, model, etc.) to reduce safety hazards.
2. Check the appearance of the battery. Check for deformation, cracks, scratches and leakage. The battery terminals should be clean, free of rust, and the markings should be clear.
3. Do not buy modified batteries. Illegal modification of batteries can easily damage the safety performance of the entire vehicle’s electrical circuit, thereby causing faults such as overload and short circuit of the vehicle’s electrical circuit. It is recommended not to buy batteries that are significantly lower than the original price!
Precautions for daily use of electric bicycles (lithium batteries)
1. “Five Don’ts”: Do not use a charger that does not match the battery voltage to charge, do not place the electric vehicle battery in a high temperature or hot environment, do not charge the electric bicycle battery product for a long time, do not bring the battery to public enclosed places such as buses and elevators, and do not disassemble, replace or assemble the lithium battery by yourself.
2. Avoid heating the plug during charging. Lithium-ion batteries with fast charging function are prone to plug heating and heating when the power plug or charger output plug is loose or the contact surface is oxidized. Over time, the plug will short-circuit or have poor contact, which will damage the charger and battery and increase safety hazards.
3. Avoid wading and soaking. There is more rain in summer. If there is water accumulation on the driving section, you should try to avoid driving or soaking in the water. If the above situation occurs, you need to go to the after-sales maintenance point for inspection to prevent water from causing short circuits and causing safety hazards.
4. Timely repair and replacement. Most lithium batteries on the market now have a cycle charge and discharge of more than 500 times and a lifespan of about 3 years. If you find that the battery life of the electric bicycle is insufficient and the line is damaged, please replace it in time.
