How to solve the problem of light weight of lithium battery electric bicycle

As the main electric bicycle manufacturer in China, the light weight reduction of the lithium battery is one of the important means for Aucma to bring its products close to the market. Accompanied by light weight, it is required for miniaturization, energy saving and performance optimization.

Although lead-acid batteries have become the object of rectification, they are still the mainstream in the electric bicycle market, and lead-acid batteries are an important factor in the cumbersome electric vehicles. In order to achieve a lighter balance and a comprehensive balance of various performances, there are three alternatives to solar electric vehicles, nickel- hydrogen battery electric vehicles and lithium batteries. Lithium batteries are recognized as the main substitutes, and there is a light quantitative lithium battery weighs only 3 kilograms and is characterized by strong power.

Aucma's "full-life iron-powered electric vehicle" is a lightweight representative, weighing 1/3 of the lead-acid battery, of which the 36V10Ah lithium battery weighs only 4.5 kg. Aiming at the requirement of electric vehicle battery to be both slim and strong, Aucma "Full Life Iron Power Electric Vehicle" relies on the lithium-ion battery research and development technology for many years and through the lithium battery power management system based on the electrician's technology, the lithium iron phosphate battery is comprehensive. Control, tested, this battery is only 2 / 3 of the lead-acid battery; monthly self-discharge 5%, lower than 8% of ordinary lithium battery and 15% of lead-acid batteries. Battery cycle life can reach 1500~2000 times.

In addition to lithium iron phosphate battery electric vehicles, Aucma also lightweights the longer life ternary lithium electric vehicles. In order to make the entire tram lighter, Aucma has improved on the body, using magnesium alloy material, which is the lightest of the practical metals, with low density, high specific strength, large modulus of elasticity and withstand impact load great ability.

From the practice of Aucma, the method of light weighting electric bicycles actually adopts three steps: 1. Electric bicycle finally selects lithium battery; 2. Light weight of the body material; 3. Optimization of the selected lithium battery.
