What's The Difference Between A New Energy Car And A Slow Charge?
- Sep 29, 2017 -

Fast charge and slow charge are relative concepts, generally quick charging for high power dc charging, half an hour can be full of battery 80% capacity, slow charge refers to ac charging, charging process takes 6 hours -8 hours.

Electric car charging speed is closely related to charging machine power, battery charging characteristics and temperature.The current level of the battery technology, even quick charge takes 30 minutes to charge to battery capacity of 80%, more than 80%, to protect the security of the battery, the charging current must be smaller, charge to 100% of the time will be longer.In addition, when winter temperatures are low, the battery requires a smaller charging current and longer charging times.

Electric car quick charge and slow charge: why two charging modes?

We know that a car can have two charging ports, actually because there are two types of charging modes: constant voltage and constant current.Generally, the constant current and the constant pressure will be adopted so that the charging efficiency is high.The fast charge is charged quickly because the charging voltage and current are different, and the higher the current is, the faster it is charged.When you are almost full, use constant pressure to prevent the battery from overcharging and to protect the battery.

Electric car fast charge and slow charge: why quick charge has not replaced the slow charge?

Slow charging current and power are relatively small, good for battery life, and low charging cost when low peak power.A quick charge will use a large current and power, which will have a great impact on the battery pack and will have an impact on the life span.Fast charging also requires supporting equipment, such as switching to direct current, which also increases costs.

Electric car quick charge and slow charge: what matters should the electric car winter maintenance pay attention to?

At present, most vehicles use lithium battery, and at lower temperature, the performance of lithium battery will decrease to a different degree, which is shown as the charging current and discharge current becomes smaller and the battery capacity decreases.In the case of high cold, there may even be a situation where the charge is not charged.The winter driving vehicle will use warm wind, increase vehicle power consumption, and reduce the mileage of vehicles.

When electric cars are used in winter, it is normal to have longer charging time and shorter driving range.In the use, should be charged immediately after the vehicle stops, use the battery's residual temperature, can make charging faster;When planning to travel, fully consider the decline in the mileage of winter vehicles.

Electric car charging speed is closely related to charging machine power, battery charging characteristics and temperature.The current level of the battery technology, even quick charge takes 30 minutes to charge to battery capacity of 80%, more than 80%, to protect the security of the battery, the charging current must be smaller, charge to 100% of the time will be longer.In addition, when winter temperatures are low, the battery requires a smaller charging current and longer charging times.
