Why does new energy vehicle charge time become longer in winter?
Winter is approaching and the temperature is falling. There are feedback from car owners of
. The charging time of new energy vehicle has become longer. Why is
?
This is determined by the characteristics of batteries .
battery will have different performance performance in different temperature ranges.
25-40 degrees is the appropriate temperature zone for battery charging. After
is less than 25 degrees, the battery activity will decrease with the temperature drop, and the charging power of
will gradually decrease, and
causes the charging speed to slow down.
charges in a low-temperature environment, and the
battery will go through this process:
just starts to charge, the battery temperature is low,
charges less power and slower ;
At this time, the battery management system will heat while charging, and
as the temperature increases, the charging speed will gradually increase.
So when charging in winter, the charging power of
will change significantly, and the charging time of
will also become longer.

Recommended for charging in winter
NO.1 Charging after using the car
The battery temperature will rise after the vehicle travels a certain mileage. At this time, the battery is still at a higher temperature, and the charging speed is faster than after the battery cools down.
NO.2 Keep warm
It is recommended to park your vehicle in a warmer environment such as indoor parking lots to maintain the temperature of the vehicle and battery, which can maintain battery activity to a certain extent and shorten the charging time.
