Sometimes users may ask how the battery is damaged too fast, whether the battery with reduced capacity can be repaired, how to maintain the battery, etc. Here, the following are the reasons for the battery damage, battery repair and maintenance:
1. "Overcharge" causes damage to the battery
"Overcharging" is a phenomenon that excessively charges the battery of an electric tricycle and destroys the chemical and physical properties of the battery.
The electric tricycle charger charges the battery packs connected in series at the same time when charging. The battery with a higher voltage will be fully charged first, and the battery with a lower voltage will be fully charged even after it has been charging. Because the charger is based on the overall voltage It is set for charging or stopping charging. Therefore, the battery that is fully charged first will be in "overcharged" state. The "differential pressure" hour has little effect on the battery. When the "differential pressure" is large, the battery cell that is often "overcharged" will also produce an increased thermal reaction of the electrolyte, until the battery is damaged.
2. "Battery loss" leads to battery damage
The "depletion of electricity" in electric tricycles is a phenomenon that damages the coating of the battery plate due to excessive battery discharge when the battery is low and the voltage is low. It should be known that the operating voltage of any on-board electrical appliance has a standard range. If it exceeds this range, the electric appliance is easy to short-circuit or burn out. Below this range, the electric appliance cannot start or work normally, and even affects the service life. This is true of both on-board appliances and battery storage.
3. The large current discharge caused by overload damages the battery
Electric tricycles have a large current at the moment of starting and accelerating, generally reaching 20A-50A. According to the electric motor power of the electric vehicle, the normal discharge current is generally controlled within 10A. Because the instantaneous current is too large, overload means that the electric vehicle is overloaded during driving, such as excessive load and people, etc. Overload will increase the battery discharge load, and long-term high current discharge will directly affect the coating of the polar plate and accelerate The process of plate softening. In addition, the bad road conditions will also cause frequent braking and starting of electric vehicles. Such as potholes, red lights, roadblocks, etc. These are all factors that cause large current discharge. This is because the greater the motor power, the greater the discharge current and the greater the damage to the battery.
4. Battery vulcanization leads to battery damage
What is battery vulcanization? White hard lead sulfate crystals are formed on the electrode plate, and it is very difficult to convert it to active material lead sulfate during charging. This is called sulfation, or "sulfidation" for short.
