New energy standards on batteries
1. What are the battery replacement standards for electric vehicles?
20% battery degradation is the replacement standard. When the battery capacity decreases to less than 80% of the battery's new state, it should be regarded as the end of the battery life, and it should be removed from electric vehicles and enter the phase of staggered use. Therefore, if the attenuation of batteries reaches more than 20% due to quality problems, the manufacturer must replace them free of charge.
2. What are the disposal standards for electric vehicle batteries?
Generally speaking, the standard for the disposal of lithium batteries for new energy vehicles is that the battery capacity is less than 80%. If the remaining capacity is still 70-80%, it would be a huge waste of recyclingdirectly connect the battery. Proper reuse of lithium batteries is particularly important to reduce battery costs.
In fact, once the capacity of an electric battery decreases to 80%, it does not mean that it cannot be charged and discharged. This simply means that the charge and discharge capacity will be much less than that of the battery. a new battery, and the driving range will also be much shorter, the number of charging times will increase significantly, which will affect the user's car experience. For example, for an electric vehicle with a range of 500 kilometers according to the working conditions method, even if the battery capacity decreases to 80%.
3. What is the normal voltage difference of new energy electric vehicle batteries?
The normal range of battery voltage difference is 0.05-0.1V. Because during theelectric vehicle battery charging and discharging process, the voltage difference between individual battery cells will produce a battery voltage difference. Under normal circumstances, the battery voltage difference should be within 0.05-0.1V. Large or too small, it will affect the life and safety of the battery.
In addition, the battery pressure difference will change with battery life, so regular monitoring and maintenance is required. For users, the battery voltage difference can be reduced by using charger equalization charge or time equalization discharge to ensure battery performance and safe use.
4. What are the national new energy vehicle battery mitigation standards?
The national standard for the mitigation of new energy vehicle batteriesvelle is 20%.
Indeed, the battery of the new energy vehicle constitutes an important element of its power system and its performance directly affects the range and lifespan of the vehicle. According to national regulations, when a battery is used for three years or more than 100,000 kilometers, its capacity retention rate should not be less than 80% of its original capacity. This standard can ensure that the battery can maintain high cruising range and safety performance, while promoting technological progress and new energy vehicle market development.
The three national guarantees for lithium batteries are:
1. If the battery is less than 90% of its rated capacity within 15 days of the product's sale date, replace it with a new battery.
2. If the battery is used correctly under conditions nnormal and leaks or if the plastic case cracks within one year and the tested capacity is less than 60% of the rated capacity, the warranty will be 12 months.
3. If the battery is replaced with a new one, a depreciation fee will be charged at the depreciation rate of three mills per day.
Product quality must meet the following requirements:
1. There is no unreasonable danger endangering the safety of people and property. If there are national standards or industrial standards to protect human health and the safety of people and property, they must comply with these standards
2. The product has the performance that the product should have, but if the product meets these standards. exhibits defects in performance, manufactures except as indicated;
3. Comply with product standards indicated on the product or its packaging and comply with the quality status indicated byproduct descriptions, physical samples, etc.
Legal basis: Article 40 of the “Commodity Quality Law of the People's Republic of China”
If the product sold has one of the following circumstances, Seller will be responsible for repairs, replacements and returns; if this results in losses for consumers who purchase the products, the seller must compensate the losses:
(1) The product does not perform as it should have without explaining it to the advance;
p>
(2) Failure to comply with product standards indicated on the product or its packaging;
(3) Failure to comply with the condition quality indicated by product descriptions, physical samples, etc.
