The first charging time of electric vehicles is generally maintained at 8-10 hours. The first charging time of the new car battery is too long, which is easy to cause overcharging, and there are safety risks. Therefore, in the charging process to control the charging time. For the new lithium battery electric vehicle, the first charge can choose to ride first and then charge or charge first and then ride, the two ways do not have much impact on the battery.
In short, the charging time of the new national standard electric vehicle varies according to the charging method, slow charging takes 6-8 hours, fast charging takes about 1 hour, and electricity is changedThe battery pack needs to be replaced. For the first charging of the new battery car, it is necessary to pay attention to the use of precautions, avoid overcharging and undercharging, to ensure the normal use of the battery and extend the life of the battery.
Normal electric bicycle with a normal charger full charge is generally 6-8 hours, the use of fast charge can be about 1 hour. However, the use of fast charging is not good for the battery of the electric bicycle, and is not recommended. Since the electric bicycle starts to charge after charging about 96% (about 6-8 hours of slow charging), it will not automatically power off, which will lead to overheating of the charger and battery, which is very possibleFires can start.
Of course, it is not possible, because the battery can not be charged upstairs, so this is a dangerous behavior, the best way is to charge in the basement.
Under normal circumstances, electric vehicle batteries can be fully charged within 8 to 10 hours after being fully discharged. This means that the 48V20AH battery consumes around 0.1 to 0.13 degrees of power per hour, while the 48V12AH battery consumes around 0.06 to 0.08 degrees of power per hour. This suggests that charging an electric car doesn't take as much power as you might think. In fact, when the battery level is below 30%? '> What's the difference between the quick charge set and the public version?
The main difference between the public version and the fast charging set is whether it is equipped with a fast charging device. The public version usually includes only the mobile phone or electronic device itself, not the fast charger; In addition to the device itself, the fast charging kit also provides an additional fast charging appliance so that users can charge the device more quickly.
The difference between Apple public version and fast charging set: different charging speed, different charging security, different applicability. The public version of Apple's chargers usually offer standard charging speeds that are suitable for everyday use. whileThe Fast charging kit uses fast charging technology to provide faster charging speeds and save charging time.
The main difference between the Apple public Edition and the fast charging package edition is whether the fast charging appliances and data cables are included, and their prices. First of all, the public version refers to Apple's official standard version of the phone, which only contains basic accessories such as the phone, manual and warranty card. The price of this version is relatively low, suitable for those who only need the standard configuration.
The difference between the public version and the fast charge set is that there is no charger head. Because Apple has cancelled the charger head of the iPhone charger, so the publicThe opening version is exactly the same as the one bought on Apple's official website, and it is the version without the charger head. The fast charge kit is the public version with a charging head version. Public Version of iPhone: The public version of iPhone is a version of the phone produced by Apple that is not customized by any carrier.
Charging speed The biggest difference between different public versions of chargers and fast charging sets is the charging speed. The fast charge kit offers faster charging speeds, which means you can fully charge the battery in less time. The public version of the charger can only provide a slower charging speed and takes longer to charge. Different compatibility Fast chargeKits are usually only compatible with a specific model of phone, while public chargers can be compatible with more phones.
Charging speed, charging safety, applicability and other differences. Charging speed: Apple's public version of the charger usually provides a standard charging speed, suitable for everyday use. The Fast charge package uses fast charging technology to provide faster charging speed and save charging time. Charging security: The Apple Public version is certified by Apple Inc., which has high charging security, reliability and stability.
1, 2015 and 2015 stipulate general requirements, AC and DC, and communication between chargers and BMS, solving compatibility and safety issues. For example, GB/T 18481-2015 specifies the details of the interaction between electric vehicles and charging devices, and the GB/T 20234 series of standards focuses on safety and electromagnetic characteristics.
2, the main international charging pile standards are Chinese national standard GB/T, American standard combo/Type European standard combo/Type 2 and Japanese standard CHAdeMO. China's standardization system includes national standards and energy industry standards. From 2011 to the present, the national standard has undergone several revisions to address issues such as compatibility, safety and truck and pile interconnection. China's charging facilities standard system involves many aspects, such as basic standards, power supply, construction and operation, and service network.
3, the national standard covers the detailed provisions from the general part to the specific interface, including: GB/T 18481: the first part of the electric vehicle conduction charging system, mainly describes the vehicle and the charging pile/grid interaction mode, timing and other details. GB/T 18482: NoElectromagnetic compatibility requirements for on-board conduction power supply equipment, focusing on electromagnetic compatibility and safety. GB/T 18483: Standard for AC/DC chargers (stations) in conductive charging systems for electric vehicles.
4. On September 7, 2023, GB/T18481-2023 "Connectors for conductive charging of electric vehicles - Part 1: General requirements" and GB/T20233-2023 "Connectors for conductive charging of electric vehicles - Part 3: The two recommended national standards for DC charging Interface were officially released by the State Administration for Market Supervision and Administration and the National Standardization Administration Committee.
