What are the differences between power batteries and ordinary batteries? What are the types of power batteries on the market?
What is the difference between power batteries and ordinary batteries? 3. Different 4200mAh power batteries can be shined in just a few minutes, but ordinary batteries cannot be done at all. Therefore The discharge ability cannot be compared with power batteries. Therefore, the current lead -acid battery is mainly used for the ignition device of the car and small equipment such as electric bicycles. The power source of new energy vehicles is generally mainly power batteries. The power battery is actually a power source for the source of power for transportation tools. The main differences between it and ordinary batteries are: 1. Different power batteries refer to transportation transportation
The power source of new energy vehicles is generally mainly power batteries. The power battery is actually a power source for the source of power for transportation tools. The main differences between it and ordinary batteries are:
1. Different properties
Power battery refers to a battery that provides power for transportation tools. Generally, a small small -scale compared to providing energy for portable electronic devices In terms of batteries, ordinary batteries are a battery based on lithium metal or lithium alloy as negative electrode materials and using non -hydrolytic solutions. It is different from the rechargeable battery lithium ion and lithium ion polymer battery.
2. Different battery capacity
In the case of new batteries, the battery capacity is tested with a discharge meter, and the capacity of the general power battery is about 1000-1500mAh; and the capacity of ordinary batteries is in the capacity of ordinary batteries. Above 2000mAh, some can reach 3400mAh.
3. Different discharge power
A 4200mAh power battery can light up the power in just a few minutes, but the ordinary battery cannot be done at all, so the discharge capacity of ordinary batteries is completely completely discharge capacity Unable to compare with power batteries. The biggest difference between power batteries and ordinary batteries is that its discharge power is large and higher than energy. Because the main use of power batteries is to supply vehicle energy, it has higher discharge power than ordinary batteries.
4. Different applications
The battery that provides driving power for electric vehicles is called power batteries, including traditional lead -acid batteries, nickel -metal hydride batteries, and emerging lithium ion power batteries. Divided into power power batteries (hybrid power autoAnd energy power batteries (pure electric vehicles); lithium batteries used by consumer electronics such as mobile phones, laptops and other consumer electronics products are generally collectively referred to as lithium batteries, which is different from power batteries for electric vehicles.
The current main types of power batteries
At present, the mainstream technology on the market is still based on lead -acid battery technology, nickel -metal hydride battery technology, fuel cell technology, and lithium battery technology.
Lead -acid battery
The application of lead -acid batteries has the longest application history and the most mature technology. It is a battery with the lowest cost and price, which has achieved mass production. Among them, the valve -controlled sealing lead -acid battery (VRLA) once became an important vehicle power battery, which is applied to EV and HEV developed by many European and American car companies. Electric vehicles, etc.
However, the lead -acid battery is lower than energy, shorter battery life, high self -discharge rate, and low circulation life; its main raw material lead weight is large, and the environment of heavy metals may be generated during production and recycling. Pollution. Therefore, the current lead -acid battery is mainly used for the ignition device of the car and small equipment such as electric bicycles.
