1, fast charge is harmful to the battery; When the battery is charged and discharged, the batteryThe cathode and anode will shrink and expand with the release and absorption of ions, and fast charging will destroy the chemical substances on the battery, resulting in shorter battery life; When the battery is fast charged, due to the relatively high current, the thermal effect of the current will be aggravated, resulting in high temperature of the battery, which affects the safety and stability of the battery, resulting in sudden capacity reduction and permanent damage to the battery cell.
2, will damage the battery. During fast charging, the migration rate of lithium ions in the electrode particles is lower than the electrochemical reaction rate of the surface, which will cause the concentration polarization of the electrode, so that the potential difference between the positive and negative electrodes deviates from the equilibrium potential.
3, with the experiment to prove fast chargingDoes not affect battery life. OPPO's VOOC flash charge uses the principle of adding multiple balanced pipes, so that water can flow smoothly and quickly to the pool, so it is relatively safe. The first method in the following figure has safety risks because increasing pressure leads to increasing heat. The second method increases the transmission area, but it will increase the pressure of B pool instantaneously, and there are also security risks.
1, slow charging of new energy electric vehicles is better
2, new energy vehicle fast charging and slow charging compared, slow charging will be better, it is recommended to slow charging, and then choose fast charging when emergency charging. Slow charge, as the name suggests, the speed of charging is relatively slow Advantages and disadvantages of wireless fast charging ; Slow charge usually takes six to eight hours to fully charge, sometimes it may take longer. However, slow charging will not cause damage to the battery, and can protect the battery to a certain extent.
3. In summary, fast charging and slow charging each have their own advantages and application scenarios. For users who travel long distances or need to replenish power urgently, fast charging is a better choice; For daily commuting, nighttime charging or users with higher requirements for battery health, slow charging is more appropriate. Therefore, when choosing the charging method, it should be based on the specific situation and needs of individuals or enterprisesTo make the most appropriate choice.
4, charging stability: the charging process of slow charging is more stable, the loss of the vehicle is less, and it is more conducive to maintaining the good use of the battery. Disadvantages of slow charging Long charging time: slow charging takes a long time to complete the charge, and is not suitable for situations where a quick recharge is required. Limited convenience: In the absence of home charging conditions, finding a public slow charging station can be troublesome and the charging process takes a long time.
5, new energy vehicles must choose slow charge, so that the slow charge will be more durable, and the damage to the battery will be smallSome, but if there are no conditions, the impact of fast charging will not be very large, the car itself is consumable, pure tram will not have too much value, how to drive how convenient how to charge.
1, slow charge is more favorable to the battery. The fast charging feature can take a toll on your phone's battery. In fact, the advantages and disadvantages of wireless fast charging , whether it is fast charging or slow charging, will have a certain impact on battery life. Of Quick Top UpTherefore, it may have a negative impact on the battery life of the mobile phone, the main reason is that it improves the charging power, the heat generated when charging is more than slow charging, and high temperature is often an important factor to accelerate the aging of the battery.
2, if you look at it from the perspective of experience, it must be a fast mobile phone charge, it charges faster. However, from the point of view of battery maintenance, slow charging is better for battery life. At present, most companies that provide fast charge solutions have not given their impact on battery life from the battery point of view, but the battery capacity of more than 80% after 500 battery charging and discharging under the national standard is qualified, within a yearIt has little effect on usage.
3, fast charge Advantages and disadvantages of wireless fast charge : The charging time of fast charge is the same electrical appliance, fast charge a charge is shorter than slow charge a charge, fast charge higher charging efficiency. Slow charge Advantages and disadvantages of wireless fast charge : The charging time of slow charge is the same appliance, slow charge is longer than fast charge, and the charging efficiency of slow charge is lower.
4, for fast charge is good or slow charge, the answer depends on the wireless fast charge Electromagnetic induction charging, very simple, and the principle of electromagnetic induction in high school is similar, wireless charging the charging base and the terminal are built with coils, so that the two are close to the charging seat and start to supply power from the charging seat to the terminal. Many wireless charging mobile phones are this principle, but the location must be relatively uniform in order to charge efficiently. And there is also coupling radiation problem, electromagnetic wave coupling will not exist a large magnetic field leakage. There are four basic principles of wireless charging, namely, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, and the mainstream standards on the market mainly include Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging. Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction type wireless charging, when the power supply of the current through the coil(The wireless charger's power supply coil) will generate a magnetic field, and other unenergized coils (the mobile phone's electric coil) near the magnetic field will generate current to charge the phone.
