L1022 battery

Pay attention, L1022 battery technology is not easy to ignore!

With the current battery performance rising and the price continuing to fall, electric vehicles will begin to be supplied in the future. The installation of charging stations becomes an important issue, and charging time is also a problem. I want to talk about today, which is often discussed by everyone or the complexity of batteries. Hybrid cars may not look attractive when they are used, but manufacturers have overcome many difficulties, so they will be explained in this article. First of all, the most commonly used batteries are lithium-ion batteries and nickel-metal hydride batteries, but they are both good batteries. The hybrid difference electric vehicles use one of them, or until cheap and safe fuel cells come out. A brief explanation from the perspective of nickel-metal hydride batteries According to the Wiktionary, a small nickel-metal hydride battery can store 100W·h/kg of electricity, and a large nickel-metal hydride battery can store 75W·h/kg. It can store 300W·h/L of energy, which is similar to lithium-ion batteries. Both volume and weight are important for application in automobiles. This is because it will not be too large to be stored in the trunk of a car or other hiding places. It's like the reaction of the battery. The battery of the Prius electric car originally had 38 nickel-metal hydride cells connected in series, producing a voltage of 273.6 volts, a current of 6.5Ah, and weighing 53 kilograms. A simple calculation is a battery output of about 2 horsepower. Even though the Prius is a small car, adding some horsepower makes the battery pack very difficult. The amount of charge is not 100% but about 40%~60%. The second-generation battery pack is able to provide 1.3 kilowatts of energy and flow 6.5 amps at 201 volts. At a similar level. Only 2 horsepower of energy can be added in an hour. However, it is known that it can add 40 horsepower in a short time. The energy is about 3 to 4 minutes. Of course, charging during this period. By storing and releasing only this energy, the Prius fuel economy is reported to be about 38 kilometers per liter. The improvement in fuel economy can only be said to be mysterious. Even if the battery lasts for a while, it is a power that must be beyond this range. On the other hand, it is time to see how great gasoline and diesel are. And the use of the development of automotive battery technology will take some time to be more sublimated. Hybrid battery technology for automobile power batteries is developing slowly. In a hybrid system, the engine and powertrain are almost the same, saving energy through generators and electric motors. Since electric motors and generators belong to established technology, the problem of batteries is the most important. Nothing is more important than the battery life of the car and the warranty period. However, battery technology is developing slowly. Battery management is also difficult. Even hybrid cars are not easy to manage batteries. This is due to the nature of the battery. Therefore, manufacturers give batteries a warranty. This is a period of about 10 years. And also be careful to pack the battery, because batteries cannot be recalled on a large scale. First, the characteristics of the battery itself are also prone to explosion or overheating. Secondly, if left unattended, the battery will self-discharge and cause serious performance problems. So, battery management is tricky, and protecting the battery well is protecting the entire car.
