Pure electric vehicle power battery

The power battery is the key technology of electric vehicles, which determines its mileage and cost.

1) Power battery required for pure electric vehicles

The functional indicators and economic indicators for power batteries used in electric vehicles include: (1) safety; (2) specific energy; (3) specific power; (4) life; (5) cycle price; Conversion efficiency. These factors directly determine the compatibility and economy of electric vehicles.

2) Supercapacitor

The advantage of supercapacitor is that the mass ratio is higher than the power and the cycle life is long. The weak point is that the mass is lower than the energy and the purchase price is expensive, but the cycle life is as long as 500,000 to 1 million times, so the single cycle price is not high, and the lead acid battery, Energy-type lithium-ion batteries can be combined in parallel to form a power supply system with excellent performance.

3) Lead acid battery

The lead-acid battery production technology is mature, the safety is good, the price is low, and the waste battery is easy to recycle. In recent years, through the new technology, its shortcomings such as low specific energy, short cycle life, acid mist during charging, and possible lead pollution in production are constantly being overcome, and various indicators have been greatly improved, not only better. It is used as a power source for electric bicycles and electric motorcycles, and it also plays a very good role in electric vehicles.

4) Lithium ion battery with lithium iron phosphate as positive electrode

electric car

The lithium battery with the negative electrode is carbon and the positive electrode is lithium iron phosphate has good comprehensive performance: high safety, no expensive raw materials, no harmful elements, and a cycle life of up to 2000 times, and has overcome the disadvantage of low conductivity. Energy-type batteries have a mass ratio of up to 120Wh/kg and can be used in parallel with supercapacitors to form a comprehensive power source. The power type has a mass-to-energy ratio of 70 to 80 Wh/kg, which can be used alone without paralleling the supercapacitor.

5) Lithium ion battery with lithium titanate as negative electrode

The volume change of lithium titanate in charge-discharge is very small, which ensures the stability of the motor mechanism and the long life of the battery; the lithium titanate electrode has a higher point (1.5V relative to the Li+/Li electrode), and can not be generated when the battery is charged. Lithium crystal branches ensure high safety of the battery. However, since the lithium titanate electrode has a high potential, even if it is paired with a lithium manganate positive electrode having a higher electrode potential, the voltage of the battery is only about 2.2 V, so the specific energy of the battery is only about 50 to 60 Wh/kg. Even so, the battery has the advantages of high safety and long life, which is unmatched by other batteries.

Battery maintenance:

1.Please recharge the battery after discharging, otherwise the battery life will be affected

2.If the vehicle is not used for a long time, the battery should be fully charged and stored, and it should be charged every half month for about 9 hours

3.When the capacity of the pool drops sharply, a new battery should be replaced.Must use  battery with same brand, same capacity, voltage.
