The Reason Why The Battery Of The Electric Car Is Normal But Not Far Away

The electric car repair shop’s master often encounters this situation: the customer’s new battery of the electric car comes to respond within a few days. The new battery does not ride far. Is it a battery quality problem, but when we use tools to After the battery was tested, it was found that there was nothing wrong with the battery. Encountered such a situation, I am afraid that we are more troublesome, because in the eyes of customers, the electric bike is not far away, it is the battery quality problem. So what is the reason why the battery of the electric car is normal but not far away?

1. Whether the charger is qualified

Many manufacturers nowadays, in order to reduce costs, the whole vehicle is not equipped with a charger when it leaves the factory, or other chargers are shoddy. The circuit boards and internal electronic components are of poor quality and are easily damaged. The charging voltage is too high or low, and the charger protection circuit is imperfect. Such chargers will inevitably affect the battery life and continued mileage!

Under normal circumstances, as long as the charger can be charged after being plugged in, it will be regarded as normal if it automatically "changes the light" after being fully charged. However, if the quality of the charger is unqualified or the charging setting parameters drift after using for a period of time, it will cause undercharge or overcharge. Therefore, when customers report a problem with the new battery, the charger used should be tested. Here is a quick repair Xiaoxia to remind everyone to choose the original factory charger, take care of the battery, start from charging!

2. Is the quality of the controller important?

Some merchants use poor quality controllers, which have not been properly matched with the motors, resulting in inaccurate parameters and large currents when electric vehicles are running. The controller is prone to problems such as high energy consumption, high heat generation, increased loss, and offset of undervoltage parameters, resulting in shortened battery life and even early scrapping.

3. Is your motor a faulty motor?

Part of the motors in the electric vehicle market are refurbished motors, which have large power consumption, low slot fill rate, high carbon content of magnets, and even rusty magnets in some motors, resulting in insufficient power and waste of electricity. Other motor housings are made of low-purity aluminum. These "morbid conditions" will cause the motor to heat up during operation, greatly increase battery power consumption, and "strain" the battery! Don't use a brand-name motor, don't spend cheap, use "expensive"!

4. Have you ignored the brakes?

In the process of riding, if you do not return to the position in time after encountering a braking situation, the wheels will run with the brakes, thus wasting power! For some users, the brakes are too tight, the brakes do not rebound, and rolling resistance is generated, which will waste electricity. In addition, many users inadvertently pull the handbrake and run forward, greatly wasting electricity. So everyone must remember to release the handbrake when driving!

5. Are you still underestimating the heavy load exceeding the standard?

Good driving habits are also the key to an electric car running far. The continued mileage of electric vehicles is achieved without multiple people. Long-term use of overdrive gear or overloaded driving, the vehicle components are forced to run when the load is loaded, the discharge current is large, there is no current limit protection, the battery is forcibly discharged, and the continued mileage is greatly reduced.

6. Pay attention to tire pressure?

"Puff"... the tire was accidentally punctured! Riding with low air pressure is like climbing, which not only affects the life of tires and the safety of riding, but also consumes too much power when air pressure is too low.

The air pressure of an electric vehicle is generally 310-380kpa. The air pressure is low and the friction is large, which will inevitably consume more power and affect the mileage!

It often appears in the market that the electric car does not run far, but the battery is normal. In fact, the battery mileage is related to the charger, controller, motor, load size, tire pressure, etc.!

So when the electric car doesn't run far, if the battery is normal, you can find the reason and know who stole the battery?
