New environmental protection form for electric bicycles

The electric bicycle scum missed so far has become a popular vehicle for transportation on the road. At present, electric vehicles mainly use lead-acid batteries. Under the increasingly environmental protection and low-carbon initiative, some environmentally-friendly new energy sources have emerged as auxiliary electric bicycles. To seize this market, lithium battery electric vehicles and solar electric vehicles are the most obvious. The emergence of new technologies is a manifestation of the continuous development of the industry, but there is no denying that lithium battery electric vehicles or solar electric vehicles have a long way to go to replace lead-acid battery electric vehicles. The following will analyze the advantages and disadvantages of the two. With future prospects.

Lithium battery electric vehicle:

Glossary: ​​Lithium battery electric vehicle is a lithium-ion battery with large capacity.

advantage:

Small size and light weight are not only characteristics of lithium battery electric bicycle light and flexible, so that lithium battery electric bicycle has more space. Lithium batteries are 1/2 to 1/3 of lead-acid batteries. Lithium batteries provide a more rational structure and more aesthetic shape design conditions. At the present stage, due to the limitations of the volume and weight of lead-acid batteries, the designers' design concepts have been greatly constrained, leading to the similarity in structure and appearance of electric bicycles at this stage. The use of lithium-ion batteries provides designers with more space and conditions to display design ideas and design styles. Makes the application of magnesium alloy and aluminum alloy frame possible.

Lithium-electric cars are easy-to-use electric bicycles, and the total vehicle weight is reduced by at least 20%. When using the same battery with the same capacity, the mileage is extended by more than 10%. Ordinary electric bicycles weigh more than 40kg, while lithium battery electric bicycles weigh between 7kg and 26kg, meeting the requirements of the national standard for electric bicycles and meeting the development direction of the industry.

Long cycle life Lithium battery cycles up to 600 times -2000 times. Useful life of up to 3 years - 5 years. No memory effect, do not discharge as Ni-Cd, Ni-MH battery before each charge, can charge anytime, anywhere. Moreover, lithium batteries can be deeply charged and discharged, with little effect on battery life. In addition to high voltage, lithium-ion battery pack battery management system can perform high-precision monitoring and low-power intelligent management of each single cell, with perfect over-charge, over-discharge, degree, over-current, short-circuit protection, Locked self-recovery and equalization capabilities greatly extend battery life.

The pollution-free lithium battery is called a "green battery" because it has no pollution.

Disadvantages:

Due to the high cost of lithium-ion batteries, lithium-ion electric vehicles will have slightly higher prices than conventional electric vehicles. This has become a major obstacle in its promotion.

Of course, lithium-ion batteries are not perfect, for example, they have security risks. Due to the high specific energy of lithium batteries, material stability is poor. In addition, lithium-ion batteries also have a high price bottleneck.

Future trends:

At present, China's electric bicycles mostly use lead-acid batteries as a power source, but experts predict that lithium-ion batteries are an inevitable trend to replace lead-acid batteries. With the expansion of lithium-ion power battery market, cost reduction, and performance improvement, the cost-effectiveness of Li-ion power batteries will exceed that of lead-acid batteries in two to three years. It can be foreseen that the performance, price and service of lithium-ion power battery products will have a greater impact on the future development of the electric bicycle industry.

Solar Electric Vehicle:

Explanation of the name: It uses solar energy as the driving force, and converts solar energy into electrical energy to power electric bicycles through lithium batteries.

Advantages: No pollution, inexhaustible use of solar energy is undoubtedly the cleanest source of energy. Today, the environment is seriously polluted, this resource is very valuable. The development and utilization of solar energy will not pollute the environment. It is one of the cleanest energy sources. This is extremely valuable in today's increasingly serious environmental pollution. The total amount of solar radiation is the largest energy that can be developed in the world today. The earth’s lifespan is also about several billion years. In this sense, it can be said that the sun’s energy is inexhaustible.

Double choice of solar electric vehicles in addition to the same energy, but also through the lithium battery charging power supply, double choice, so you worry!

Disadvantages:

Instability and low efficiency As we all know, the sun is constrained by natural conditions and is extremely unstable and cannot be supplied from time to time. In view of the current level of solar energy utilization, there are shortcomings of low efficiency and high cost. In terms of economic benefits, practical values ​​are greatly discounted.

High prices The prices of solar electric vehicles in the market are generally expensive, making consumers discouraged.

Future trends:

If people make heavy use of solar bikes instead of cars, then each solar bike can reduce 800 kilograms of CO2 emissions every year. Green riding has become a new fashion, and in the field of electric bicycles, technological innovation is gestating the further upgrading of the industry, making the competition in the electric vehicle market more fierce, and thus driving the electric car industry to take a new round of technological revolution as the core Great shuffle. With the continuous updating of technology, solar electric vehicles can occupy a new market in the future.

Lithium battery electric vehicles and solar electric vehicles have irreplaceable advantages that are in line with human development trends. However, we can also see that there is still a lot of room for improvement in both of these areas. Technological advances will enable them to truly enter the lives of ordinary consumers and truly become environmentally friendly, low-carbon, inexpensive and cost-effective vehicles. .
