Low carbon e bike accessories

The low-carbon concept of electric bicycle comes from the assembly of energy consumption index of each component. To investigate whether e bike accessories is low-carbon products, it is mainly to investigate the actual work energy consumption index of components such as battery, motor, charger and controller of e bike accessories.

Objectively speaking, the battery system of rear motor and controller, its energy consumption index of pure technical measurement is relatively easy to work, motor, for example, electrical energy to mechanical energy conversion efficiency has always been one of the main indicators of performance measure motor, as for commercial promotion of intentionally vague concepts, such as the concept of different conversion efficiency under different torque, also it is not difficult to discern for professionals. In the low-carbon background of energy saving demand, more and more car manufacturers will pay more attention to comprehensive cost performance, and the market will tend to choose products with high conversion efficiency under different torques. Even if some manufacturers choose to assemble high-energy and low-price motors, as long as the market mechanism makes explicit and standardized technical indicators for product matching, and even guides consumers with energy-saving star marks, it is easy to get on the right track in the long run through the market feedback mechanism and the new regulations of consumer association.

For the battery and the motor and controller in the front of the system, the investigation of the working energy consumption index is relatively complex, and it is necessary to obtain a consensus through repeated technical discussion. Battery charging conversion efficiency: In the national technical standard for lead battery of electric moped, the charging conversion efficiency is not considered as a special technical index, so the measurement problem of how much power the battery needs to be charged to be full is inadvertently hidden. In fact, when different batteries of the same capacity are charged with the same constant voltage, they consume very different amounts of electricity when they are fully charged (technically defined as when the current drops to a certain value for a certain period of time). From the concept of low carbon economy, of course, the less energy consumed, the higher the charging conversion efficiency, the better, therefore, charging batteries with high conversion efficiency can be understood as low carbon products; Conversely, belongs to the same kind of high carbon products.

The charger is one of the most easily ignored e bike accessories and has the greatest impact on the battery. The concept of high carbon product of low price and poor quality charger is not mainly about its own energy conversion efficiency, but about the influence of poor quality charger on battery life and power grid pulse interference. Generally understood as, the inferior charger constant pressure floating is too large, especially not according to the environment temperature feedback automatically adjust the constant pressure value, is leading to the battery life far less than the design value of the direct killer. Due to the need of manufacturing cost or one-sided pursuit of conversion efficiency, some inferior chargers often do not design, install or simplify the grid filter, resulting in the use of products in the grid interference. A few inferior chargers are purely micro-interference to the power grid, but when tens of thousands of inferior chargers are parallel micro-interference to the power grid, the comprehensive effect is difficult to ignore, and its bad result can only make the power grid pay for the high carbon characteristics of this inferior charger. This kind of inferior charger, of course should be listed as high carbon products.
