Is there a reason for the short battery life of electric vehicles in summer?

1. The charger problem Many times, some users like to buy some cheap chargers online, and these chargers are often made by the factory, and the quality cannot be guaranteed. The most straightforward manifestation is that the internal components of this charger are easy to fall off, and once there is a problem of falling off, the charging voltage will be unstable, and there will be a situation where the charge cannot be charged or the charge is not fully charged, or even the charge is broken. Battery, and this will cause the electric car to run short, and the battery life will be shortened. 2. The problem of the controller is an important part of the electric vehicle, which plays a role of distribution and control during the entire operation of the electric vehicle. In addition, the controller is also one of the most used accessories, which means that its loss rate will be relatively faster. Generally speaking, after three years of use, the controller will have aging problems more or less. Once aging occurs, the controller will make the current distribution uneven, appear too large or too small, and this will also lead to The electric car didn't run far, and the battery life became shorter. 3. Motor problems. In summer, because it is a season of heavy rain, many users will not wipe out electric vehicles after riding in heavy rain. However, due to such negligence, it is very likely that water will enter the motor. The embodiment of straightness is that the motor is rusty and demagnetization is aggravated, which will cause problems with the speed of the electric vehicle and cause the electric vehicle to shorten the battery life. Fourth, the problem of excessive load. Due to its own convenience, many users will use it to carry people or load goods, and this will exponentially accelerate the speed of battery consumption. For example, if a 48V simple electric vehicle has a rated driving range of 40km, when two people are driving, the battery life may only reach 30km or even lower. In addition, if the load exceeds the limit for a long time, the battery may be damaged and the battery may not be durable. The problem of short battery life in summer electric vehicles is not necessarily due to the battery, but may also be caused by the four major causes of charger, controller, motor, and excessive load. Regarding electric vehicle users, no matter what the reason is, the maintenance of electric vehicles must be strengthened, so as to maximize the endurance of electric vehicles.
