After the implementation of the new national standard, four basic requirements have been put forward for lithium batteries for electric bicycles.

Opportunities are accompanied by challenges. After the implementation of the new national standard, consumers have put forward higher requirements for the performance of electric vehicles, which also means that the energy density, battery life, life, quality, and environmental protection of lithium batteries have brought higher performance. challenge. After the implementation of the new national standard, four basic requirements have been put forward for lithium batteries for electric bicycles. 1. High energy density. High energy density means higher battery capacity and volume ratio. The new national standard requires that the maximum speed of electric bicycles is not more than 25km/h, the motor power is less than 400W, and the vehicle mass is not more than 55kg. This means that electric bicycles must be reduced. The weight does not reduce performance at the same time, so the ternary lithium battery with lighter weight, higher capacity and better performance is bound to become the first choice. BAK battery is continuously breaking through energy density in the field of small power. The battery capacity has been increased from 18650-2.5Ah to 21700-5.0Ah, and the volume specific energy density has been increased from 544Wh/L to 743Wh/L. 2. Long cycle life The cycle life of lithium batteries directly affects the service life of electric vehicles. Under different temperature conditions, whether they can be charged and discharged multiple times, they can still maintain a high battery capacity after deep cycles. The BAK NCM battery is compatible with normal temperature and high temperature cycles, and is suitable for different scenarios. It can maintain more than 90% of the battery capacity under a thousand cycles of normal temperature. 3. The use scenarios of two-wheeled electric vehicles with strong temperature adaptability are relatively complicated. To ensure that the electric vehicles can work as usual in the severe cold of -20°C and the intense heat of 45°C, the lithium battery needs to be able to take into account high temperature storage and high and low temperature discharge performance. , Suitable for different environments. 4. High safety Safety is the basic performance of electric vehicles, and battery safety is a particularly important part of it. From the protection settings of the BMS to the anti-vibration and explosion-proof structure of the battery, it ensures the safe use of the lithium battery of electric vehicles in the changing environment.
