Usually 20-25KWHBattery capacitycan travel 150-200 kilometers. This is linked to the cruise autonomy requirement.
Typically, when charging a 48V20AH battery, it takes about 1.08 kilowatt hours of electricity per charge after fully discharging. The general charging time is 8-10 hours, which is the power consumption. per hour of charging is 0.1 to 0.14 kilowatt hours of electricity.
Early R&D
Lithium batteries were first used in pacemakers. Lithium batteries have the advantages of extremely low self-discharge rate and gentle discharge voltage, allowing pacemakers implanted in the human body to work for a long time without recharging. Lithium batteries typically have a voltage rating above 3.0 volts and are best suited for use as an internal circuit power supply.graciously. Manganese dioxide batteries are widely used in calculators, digital cameras and watches.
In order to develop more efficient varieties, various materials were researched to create unprecedented products.
In 1992, Sony successfully developed lithium-ion batteries. Its practicality has significantly reduced the weight and volume of portable electronic devices such as cell phones, laptops and calculators.
Lithium batteries and lead-acid batteries are currently commonly used battery types for electric bicycles. They each have their own advantages and disadvantages. The best solution depends on individual needs. user.
Advantages of lithium batteries: Lithium batteries have smaller size, lighter weight, higher energy density, longer lifeus longer, higher performance, higher security and better usability. Lithium batteries can use fewer battery packs, smaller size, lower cost, less maintenance, higher reliability and higher feasibility.
Advantages of lead acid batteries: 1. Lead acid batteries are relatively cheap, inexpensive and much cheaper than lithium batteries. 2. Lead-acid batteries have good thermal stability and can withstand temperature changes and maintain good performance even at high temperatures.
