Electric cars to choose lithium battery or lead acid battery?

Source: 2020 - 04 - 20 confusion hits: electric cars using lithium-ion battery or lead acid battery? With the support of national policy and the electric car of the new national standard come on stage, the development of lithium battery in the huge opportunity. But we cannot treat as the same. Before we make our final decision, we look at the pros and cons of them. Which is more suitable for lithium battery and lead acid battery electric cars? Compared with lead-acid batteries, lithium batteries have a higher average voltage and energy density. In other words, the same size of lithium batteries have greater capacity. In addition, the lithium battery is relatively light, easy to carry, is relatively much longer service life. In addition, the lithium battery in high temperature and low temperature adaptability is stronger, less influenced by temperature factors, more environmentally friendly. Lithium battery, of course, there are three shortcomings, its security and stability are relatively poor, if improper operation, it is easy to the risk of explosion. In addition, the lithium battery can't discharge current is big, high production requirements, cost is higher also. Compared with lithium batteries, lead-acid battery is relatively cheap, more easily accepted by the public. In addition, the lead-acid battery better high rate discharge. Most importantly, lead-acid battery than lithium battery recycling costs are higher. Lead-acid batteries, however, also has its own shortcomings, such as heavy metal to cause pollution to the environment; Compared with lithium batteries, lead-acid battery energy density is lower. And it's not as long as the lithium battery service life. In short, the emergence of lithium battery products achieve the development of the electric car industry, but instead of lead-acid battery, the technology must be reached the height of the match, at the same time improve the cost performance, accepted by more people. What kind of lithium batteries of electric cars is better? 1. Each piece of high quality lithium batteries are consistent control! All battery scan code in the sorting device sorting, computer according to the content of the scan code automatically record the capacity, internal resistance, voltage of the battery. Second, all the monomer battery type spray capacity, wH, bar code, batch number, the traceability production date code. 2. High quality lithium battery adopt domestic most advanced welding equipment connected battery strings. Spot welding position and current is set parameters monitoring by the computer. 3. Each group of high quality lithium batteries, adopts domestic advanced ageing equipment to 100% finished product ageing capacity test. When the batteries in the following two situations, is out of the shipment. First of all, when the battery capacity had been cycle for three weeks, if fell more than 0. 02%, it will be delivery. When the high temperature aging voltage ( The pressure drop) Differences, a battery voltage between each string for more than 15 mv will not shipment. 4. High quality lithium battery, support the most advanced BMS protection system, has developed a patent. Effectively prevent the protection of electronic components in the system function such as waterproof, high temperature resistance, oxidation, impact, in the process of normal use lithium battery protection ( The overcharge, over discharge, short circuit, undervoltage, over current, temperature control) 。 When you first lithium batteries for electric cars, you need to pay attention to? 1. Auto lithium battery charging time for the first time, because the car battery when not in use in the factory has never experienced a charge and discharge, so we need to ensure the normal operation of the battery. Generally speaking, the charging time is about 5 - 6 hours, so that the battery can be fully charged, the charging point to longer after use. 2, charge for the first time, although not the first time to collect fees, but the second is a new car, so you can do a battery power is about to run out of time, and then long time charging, charging can keep eight 9 or 10 hours, in order to make the battery chemistry to make a complete cycle. 3, battery car charge for the first time, the charger can quickly generate heat, heat is very high, therefore, especially in the summer, when charging, the charger is not easy to hot burning object, it is best not to put battery car seat, prevent fire. Lithium battery only do this detail, can fully guarantee the consistency and stability of the product, can achieve more on the development trend of lithium batteries. Hope that more lithium battery manufacturers focus on the product itself, increase product added value, make lithium-ion batteries more popular with the users.
