The number of electric forklift batteries is basically around 800 to 1,500 times. Wrap the brand, according to the environment, the service life of a set of batteries is not equal, then how is this time in 1-5 years? ? Why many enterprises can reach 5 years, some or less than 1 year, these data is worth reflecting, after all, a group of traction all-electric fork car battery is not cheap, small picked a few arguments Talk:
1. Due to the short interval of the vehicle, the vehicle is frequently started, the whole electric forklift is parked, and the battery consumes relatively large during operation, and the vehicle charging system is relatively large for the charging current of the battery.
Long-term high current charging will increase the inner water synthesis of water in the battery, the battery is abandoned, and too much detonate will reduce the separation of the active substance to the gate, form the active substance to fall, and all electric forklift batteries. The electrolytic solution is mixed, and too much precision will increase the gas pressure inside the battery. If the exhaust is not smooth, the water intake in the battery is in the absence of the gas pressure.
Splashing the battery; Since the action of the heart force occurs inside the battery, the local electrolyte will be brushed to the exhaust portion in the charging operation, if the exhaust depol is designed or unreasonable, it may present an electrolyte proof; due to the electric forklift Poor vibration, request the device of the exhaust gas plug on the battery requests strong.
At the same time, since the vibration is large, it is possible to form a battery damage: there is a wire welding portion or a bus row site. The internal spark is shorted, and the positive and negative short circuit may form the internal pressure of the battery. The internal pressure is too large, and the simultaneous formation The mechanical zeroing of active material, and the electrolyte turbidity.
All electric forklift driving safety, energy saving and environmental protection, in the process of corporate production and storage, the role of electric electric forklifts is gradually highlighted. Each industry has a rapid growth of the demand for all-electric forklifts. The cost of electric forklifts from the battery is from the battery. The same battery is different. It is different from the use of the use. The relative operation is also a non-small gap. What is the reason why the electric forklift battery life is short?
First, the quality of themselves, such as reducing lead, poorly balanced in the battery pack; balanced differences lead to a sharp decline in the life of the entire set of battery life.
Second, the charger does not match cause overcharge and over-discharge, which is the main reason for the polarization of the battery. Battery plate aromaticization is the root cause of battery life.
Third, improper use, such as the "second super" discharge stage mainly discharged current value, that is, long-term exceeding the amount of discharge, called "two super", which is one of the main reasons for battery polarization, very good harmful. The root cause of battery capacity is reduced: battery polarization is the root cause of battery life. Battery polarization, that is, the active substance used to store and convert energy in the battery, resulting in less battery capacity. There is a shortage of polarization reasons:
1. Insufficient charging of the battery or the initial charge interruption time;
2. The battery is long-term charging (under charge);
3. Failure to charge after discharge;
4. Frequently overcharge or small current depth;
5. The electrolyte density is too high or the temperature is too high, and lead will in-depth formation is not easy to recover;
6. The battery has a long time, and it is not used for a long time without regular charging.
7. The internal short circuit partial role or the battery surface will cause leakage;
8. The internal electrolyte surface of the battery is low, which makes the polar plane naked.
