1, the charging current and power of slow charge are relatively small, the service life of the battery is better, and the charging cost is low when the electricity is low. Fast charging requires the use of large current and power, which will have a great adverse impact on the battery packRing, will also have a certain impact on life.
2, the main difference between fast charging and slow charging of new energy vehicles is that the charging speed is different, the difference between fast charging and slow charging of new energy vehicles is as follows: Charging time In general, slow charging of new energy vehicles takes 810 hours to fully charge the battery, and fast charging only takes 1 hour to charge the battery to 80% of the electricity outside.
3, fast charge and slow charge is a relative concept, generally fast charge for high-power DC charging half an hour can be filled with 80% of the battery capacity Slow charge refers to the AC charging process takes 6-8 hours. The following is about the charging pileCharging time: Under the current battery technology level, even fast charging takes 30 minutes to charge to 80% of the battery capacity. After more than 80%, the charging current must be smaller to protect the battery safety. The charging time to 100% will be longer.
4, the charging time is different, the impact on the battery is different, the charging mode is different. Charging time is different: fast charging for half an hour can be charged 80%, slow charging takes 6-8 hours to be full. The impact on the battery is different: fast charging will have certain damage to the battery, and slow charging will be better for the life of the battery. Charging mode is different: fast charging does not need to go through the car charger conversion, directlyAccess to the car battery, slow charge needs to be converted by the charger.
5, the charging time is different, fast charging half an hour can be charged 80%, slow charging takes 6~8 hours to be full; The impact on the battery is different, fast charging will have certain damage to the battery, slow charging will be better for the battery life; Different charging modes, fast charging does not need to be converted by the car charger, directly connected to the car battery, slow charging needs to be converted by the charger. Under normal circumstances, the fast charge interface is 5, and the slow charge is 7.
Efficiency problem Wireless charging is subject to the development of technology In-vehicle wireless charging fast charging evaluation , charging efficiency is still relatively poor in-vehicle wireless charging fast charging evaluation , Because the power of wireless charging itself is small Car wireless charging fast charge evaluation , and the actual performance is not stable.
Slow charging speed. Although wireless charging is convenient Car wireless charging fast charging evaluation , the charging speed is much slower than that of data line charging, because wireless charging can only receive electrical energy through the electromagnetic field in the coil. The base tends to heat up. Wireless charging in the process of use will have a certain amount of energy loss, resulting in wireless charging location heat, if the heat is serious, there may be certain security risks.
The charging speed is slow. Wireless charging, while convenient, is relatively slow because it can only receive electrical energy through an electromagnetic field within the coil. The base tends to heat up. During wireless chargingDue to certain loss, the charging position may heat up, which may bring security risks if it is serious.
High parking accuracy requirements In principle, the relative position between the car end and the ground end coil will significantly affect the charging power and efficiency. It is unrealistic to expect users to park their cars with centimetre accuracy every time. Therefore, engineers need to start from the line design and calibration, make the position error tolerated by the system as large as possible, and weaken the requirements for the accuracy of the parking position.
Because the charger and the appliance transfer energy through the magnetic field, there is no wire connection between the two, so the chargeDevices and electrical appliances can be exposed without conducting contact. According to Baidu Encyclopedia, the wireless charging of mobile phone charging is actually low-power wireless charging, that is, electromagnetic induction charging, and wireless charging in the car is actually the output of electromagnetic induction wireless charging in the car.
Compared with the traditional charging method, the biggest advantage of wireless charging in the car is that the adaptation rate is high, mobile phones that support the Qi wireless charging protocol can be charged, and you do not have to carry all kinds of charging lines when you drive out, which can effectively avoid the situation of many messy lines in the car.
Electric vehicle wireless charging technology has become a hot electric vehicle to become the mainstream, the problem of battery life has not stopped, in order to solve the battery life problem, the various car companies have also tried their best to find a way to solve this problem, in addition to the power change and fast charge, in fact, there is a different way, that is, road charging, Let the car run along the road.
The logic behind the wireless charging technology used by Germany's WIFERION in the modified Model 3 is electromagnetic inductionLine charging. At present, the modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the fastest one hour to make up 80 kilometers, full may take about 6 hours.
The wireless charging process will definitely heat up. As long as the temperature is not very high, no problem, you see if there is something around the block, because many times love to put some things on it. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
1, first use Apple 18W PD charger with Apple MagSafe magnetic wireless charger to charge iPhone 13 Pro Max, the charger output 9V voltage, power is 42W. Replace the Apple 18W PD charger with an Apple 20W PD charger, and the power of the charger output is 93V 84A 153W. Use the Apple 30W PD charger to charge the iPhone 13 Pro Max at 90V 40A 153W.
2, Bex wireless charger: cost-effective, 15W charging, strong suction and user-friendly design, even game lovers can easily use. Multi-in-one style Rui quantity three-in-one charger: 22W wireless fast charge, strong compatibility, dual core design to ensure low loss, intelligent heat dissipation makes charging more secure. Green Link 3-in-1 Charger: Compatible with Apple Watch, iPhone and AirPods, the phone module swipes to provide an elegant desktop solution.
3. For example, Belkin's Boost↑Charge Pro wireless chargers and Mophie's 3-in-1 wireless chargers are both excellent options that offer good charging efficiency while also ensuring safe charging. When choosing a wireless charger, you also need to take into account some other factors, such as charging speed, the size and weight of the charger, and whether it is easy to carry. The above recommended brands and products have good performance in these aspects.
4, can be charged. Because the iPhone13pro mobile phone supports Qi wireless charging standard technology, Xiaomi's car wireless charger also has Qi protocol, but the charging efficiency will be very slow. So the iphone13pro can use Xiaomi car wireless charging.
5, Apple 13pro support car wireless charging. According to the inquiry Apple mobile official website shows that the Apple 13pro series supports on-board wireless charging. The Apple 13pro series supports MagSafe magnetic charging technology and can be charged wirelessly via the MagSafe wireless charger. If the car charger supports MagSafe magnetic charging technology, then the MagSafe wireless charger can be used in the car for wireless charging of Apple 13pro series mobile phones.
6, its appearance can be said to be small and beautiful, the appearance is really beautiful, as a magnetic charger, the price of 197 yuan is still good, the maximum support of 15W wireless fast charge, for some mobile phones have wireless charging but there is no wireless charger in the car, buy it on the right, on the car, beautiful and powerful.
2, constant current charging method: the charging current remains constant during the charging process, referred to as constant current charging method, or constant current charging method or constant current charging method. On charge
