Do new energy vehicles need to be recharged without power?
Cars can be charged with new energy at any time. The charging of electric vehicle power battery is not like other electronic products. When batteries are exhausted, they are charged. For the battery, it is actually very unreliable to charge the car after it is used up, which will cause great damage to the battery. The life of the battery depends on the number of repeated charge and discharge. The lithium battery can be continuously charged and discharged for about 1500 times. After that, the performance of the battery will be greatly weakened. We should try to avoid recharging after all the remaining batteries are discharged.
Battery performance:
With the increase of charging times, the performance of the battery will gradually weaken. If the electric car is recharged after it is dead, it will cause some damage to the battery. But if used and charged, the battery life cycle will be longer. If you charge with 50% of the vehicle's remaining power, there are only 0.5 cycles.
Precautions:
You don't need to worry about the cruising range of the vehicle, you can't find a charging pile, or even line up for charging. Therefore, you should pay more attention when charging the electric car, and charge the electric car while using it to prolong the service life of the battery of the electric car.
Do New Energy Vehicles Need Palladium?
New energy vehicles do not need palladium.
Introduction of palladium:
Palladium, one of the rarest precious metals in the world, with element symbol Pd, is one of the platinum group elements. The purity of palladium is extremely high, and its appearance is similar to platinum. In the natural state, it has a silvery metallic luster and never fades. Palladium has high temperature resistance, corrosion resistance, wear resistance and ductility. In terms of purity, rarity and durability, it can be replaced by platinum, which is an ideal material for making jewelry and inlaid gems. Palladium, platinum, gold and silver are one of the international precious metal spot and futures trading varieties, which were once higher than platinum in history. In addition, palladium is also a widely used catalyst, from petrochemical industry to medical treatment, from automobiles to watches.
Chemical properties of palladium;
Palladium is chemically stable, insoluble in hydrofluoric acid and resistant to phosphoric acid, perchloric acid, hydrochloric acid and cold sulfuric acid. Sodium hydroxide, sodium carbonate and sodium peroxide can corrode palladium in aqua regia, hot concentrated sulfuric acid and concentrated nitric acid. Palladium is not easy to oxidize and lose its luster at room temperature. When the temperature is about 400℃, oxides will be produced on the surface. At room temperature, when heated to 800℃ in air and humid environment, palladium oxide film will be formed on the surface of palladium. Palladium has pure white charm, bright color and is as natural as platinum. It also looks like platinum, but the price of palladium is lower than platinum. Because palladium has some unique physical and chemical characteristics, its jewelry processing is more difficult than platinum, and all aspects are very demanding.
