Why doesn't the electric vehicle battery run far?

Nowadays, once many electric car users have the problem that the electric car does not run far, it is attributed to the poor quality of the battery, and the battery is required to be replaced. Even after the battery is tested to be normal, it is still considered to be a battery problem. There are many problems that are not far away, and the cause is not necessarily the battery. Some dealers said that the current cause of electric vehicles to run is not far, more than 80% is caused by non-battery reasons. 1. Poor quality of the charger will cause damage to the battery. Nowadays, in order to reduce costs, many miscellaneous charger manufacturers use circuit boards and internal electronic components that are of poor quality and are easily damaged, and the charging voltage is either high or low. The use of such a charger will inevitably affect the durability and mileage of the battery! Please choose a well-known charger manufacturer. The charger is a good partner for the battery. Take care of the battery. 2. The quality of the motor is not good and the power consumption will be high. Some of the motors on the market are refurbished motors, which have high power consumption, low slot full rate, high carbon content in magnets, and even rusty magnets in some motors, resulting in insufficient power and waste of electricity. In addition, some motor shells use regenerated Aluminum is recycled and made with insufficient purity. These morbid conditions will cause the motor to heat up during operation, which greatly increases the loss of battery power and strains the battery! When buying an electric car, don't be greedy for a cheap electric car, don't use a brand-name motor, don't spend cheap, use expensive! 3. Controller problems will cause unreasonable current control. Some controllers are of poor quality. Due to workmanship, control boards, and inaccurate parameters, the current is too large, the undervoltage parameter offset, etc., all affect the control of the battery power, which leads to shortened mileage and early termination of battery life! 4. Brake power failure, resulting in waste of power. If there is no brake power failure, it is easy to be dangerous. Accelerating the speed and adjusting the brake will not return to the position, and it will run with the brake, which will waste a lot of electricity from fatigue work of the whole vehicle components! If you want an electric car to not want the battery to run away due to the brakes, repair it if there is no brake power failure! More for safety! It is also for the life of the battery! 5. The load exceeds the standard and the power consumption increases. Nowadays, electric vehicles are overloaded for pulling goods, and things that can pull 300 catties have pulled 800 catties. The car moves like a snail, and the electric car becomes your slave. When the load is loaded, the parts of the car are forced to run, and the discharge current is large. Without current limit protection, the battery is forced to discharge, causing serious damage to the internal vitality of the battery and shortening the damage to the battery!
