602030 lipo battery

　　What are the classifications of new 602030 lipo battery and how to maintain them?

　　New 602030 lipo battery can be divided into lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, lithium iron phosphate batteries, etc.; in daily maintenance, pay attention to correctly grasping the charging time, protecting the charger, and deep discharging regularly. The following is a detailed introduction to "Classification and Maintenance of New 602030 lipo battery".

　　1. Classification of new 602030 lipo battery

　　1. Lead-acid battery

　　As a relatively mature technology, lead-acid batteries are still the only battery for electric vehicles that can be mass-produced due to their low cost and high-rate discharge capability. During the Beijing Olympics, there were 20 electric vehicles using lead-acid batteries to provide transportation services for the Olympics. However, the specific energy, specific power and energy density of lead-acid batteries are very low, and electric vehicles using this as a power source cannot have good speed and cruising range.

　　2. Nickel-cadmium batteries and nickel-metal hydride batteries

　　Also known as hydrogen storage alloy, it has the characteristics of high energy density, fast charging, and long cycle life. Its performance is better than lead-acid batteries and lags behind lithium batteries. Nickel-metal hydride power batteries have just entered a mature stage and are currently the only battery systems used in hybrid vehicles that have been actually verified and commercialized on a large scale. The existing market share of hybrid batteries is 99%.

　　3. Lithium battery

　　Traditional lead-acid batteries, nickel-cadmium batteries and nickel-metal hydride batteries have relatively mature technologies, but there are big problems when they are used as power batteries in cars. At present, more and more automobile manufacturers choose to use lithium batteries as power batteries for new energy vehicles. Because lithium-ion power batteries have the following advantages: high operating voltage (3 times that of nickel-cadmium batteries and hydrogen-nickel batteries); large specific energy (up to 165WH/kg, three times that of nickel-hydrogen batteries); small size; light weight ; Long cycle life; low self-discharge rate; no memory effect; no pollution, etc.

　　4. Lithium iron phosphate battery

　　Lithium iron phosphate battery is also a lithium battery. Its specific energy is less than half that of lithium cobalt oxide battery, but it is highly safe, can cycle up to 2,000 times, has stable discharge, and is cheap, making it a new choice for vehicle power.

　　5. Fuel cell

　　Simply put, a fuel cell is a power generation device that directly converts chemical energy present in fuel and oxidant into electrical energy. Fuel and air are fed into the fuel cell respectively, and electricity is wonderfully produced. It looks like a battery with positive and negative electrodes and electrolytes on the outside, but in fact it cannot "storage electricity" but is a "power plant". Fuel cells are environmentally friendly and have high energy conversion rates. With the advancement of technology, they are the most promising power battery in the future. At present, fuel cells have entered the market introduction stage from the development stage. Due to the current high cost and technical limitations, they cannot be promoted on a large scale. However, various countries have always attached great importance to the development of this industry.

　　2. How to maintain new 602030 lipo battery

　　1. Correctly grasp the charging time: After picking up a new car, the electric energy must be replenished in time to keep the battery fully charged. During use, you must accurately grasp the charging time according to the actual situation, refer to the usual frequency of use and driving mileage, and control the charging time yourself. During normal driving, if the red and yellow lights on the battery gauge are on, you should charge it; if only the red light is on, you should stop running and charge as soon as possible. Excessive discharge will shorten the battery life. The charging time should not be too long, otherwise it will cause overcharging and cause the vehicle battery to heat up. Overcharging, overdischarging and undercharging will shorten battery life. During the charging process, if the battery temperature exceeds 65°C, charging should be stopped.

　　2. Protect the charger: There are instructions on protecting the charger in the new energy vehicle instruction manual. Many users do not have the habit of reading the manual carefully, and they often only think of looking for the manual when something goes wrong. In addition, you need to pay attention to keeping the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also cause damage to the battery.

　　3. Regular deep discharge: Regular deep discharge of the battery is also helpful to "activate" the battery, which can slightly increase the battery capacity. After the battery undergoes under-voltage protection for the first time, the voltage will rise after a period of time and return to the non-under-voltage state. If the battery is used again at this time, it will cause great damage to the battery. After complete discharge, fully charge the battery, and you will feel that the battery capacity has increased.

　　4. Maintain sufficient power: In daily use of new energy vehicles, the battery must be kept fully charged, the vehicle speed should be controlled, and the driving mileage should be 1/3~2/3 of the longest driving mileage. If you drive 10~20km a day, it is best to replenish the battery every two days; if you drive more than 100km a day, you should replenish the battery on the same day to keep the battery in a "full state" for a long time. If you leave it idle for a few days before recharging it, it will easily become sulfated and the battery capacity will decrease.

　　5. It is strictly prohibited to lose power during storage: The vehicle battery is strictly prohibited to be in a state of power loss during storage. The depleted state means that the battery is not charged in time after use. If the battery is stored in the depleted state, it is easy to undergo sulfation. The lead sulfate crystals adhere to the plates, which will block the ion channels, resulting in insufficient charging and reduced battery capacity. . The batteries of new energy vehicles need to be stored after being fully charged and recharged once a month to maintain the health of the battery and avoid long-term loss of power that will lead to sulfation of the battery plates. The longer the vehicle is idle, the more serious the damage to the battery will be.

　　6. Avoid large current discharge: When starting, carrying people, or getting on board an electric vehicle, try to avoid slamming on the acceleration, which may cause instantaneous large current discharge. High current discharge can easily lead to the formation of lead sulfate crystals, thereby damaging the physical properties of the battery plates.
