For the current new energy lithium rechargeable forklift, prolonging the service life and performance of the battery is a problem that can not be ignored in the use of lithium forklift. Overcharge or under charge of the battery will shorten its service life and adversely affect its performance.
Here, the "Qiancheng power" forklift lithium battery brand introduces in detail the safety precautions that must be observed in the forklift battery charging operation, and briefly introduces the three common battery charging methods of traditional charging, opportunity charging and fast charging, hoping to help you in the process of using the forklift with lithium battery.
1、 Safety precautions for forklift battery charging
When charging the forklift lithium battery, many safety precautions need to be observed. These precautions are very important to ensure the safety of workers charging the battery and prevent damage to the battery and charging equipment. If workers do not follow safety precautions, they may seriously injure themselves due to current or dangerous chemicals contained in the battery.
If the battery or charging equipment is damaged or malfunctioned, due to the current and the presence of combustible toxic chemicals in the battery, it will not only pose a potential safety hazard to the personal safety, but also to the entire operation site. In order to greatly improve the safety when charging the forklift battery, the forklift battery manufacturer recommends to follow the following safety precautions.
1. Before charging the forklift, the forklift should be firmly parked in a safe position
2. All battery compartment covers must be kept open to eliminate any gas accumulation during charging.
3. In all battery charging areas, it is important to provide adequate washing, cleaning and safety equipment. Including but not limited to eyewash, chemical cleaning kit to prevent chemical spillage and fire extinguisher to extinguish any fire caused during battery charging.
4. The building for battery charging must be properly ventilated to ensure that any gas generated during charging can be safely dissipated. All battery charging rooms need to be designed and constructed in accordance with Australian building code standards to ensure compliance with work safety regulations
5. All charging components must be in good working condition, and the connector shall not be damaged or broken. Only properly trained and authorized personnel can charge and replace batteries because they can quickly identify potential problems and have been trained in response methods.
6. Appropriate personal protective equipment, including masks, aprons and rubber gloves, must be worn at all times during battery charging to reduce the possibility of damage to eyes or skin caused by battery acid. Workers who charge the battery must comply with the following additional precautions: no smoking, no open fire, no sparks, no use of mobile phones or similar electronic equipment, and do not use inflammables and metal objects that will produce sparks.
2、 Type of forklift battery charging
1. Conventional charging
Conventional forklift battery charging is common and direct, and the battery is charged overnight as standard. Overnight charging usually lasts eight to ten hours, causing the battery to charge to 100% capacity. In the traditional charging process, the battery will heat up, so it needs to leave enough time for proper cooling before operating the forklift. Traditional forklift battery charging is suitable for single shift operation or applications where forklifts can use multiple batteries. Conventional battery charging allows you to greatly extend the battery life, but it may not be a better solution for multi shift operation.
2. Fast charging
Fast charging is suitable for multi shift operation without time to charge the battery. Fast charging uses a higher current and does not reduce the charging rate like the traditional charger, which enables the battery to be fully charged within half to two to four hours of the traditional charging time. Fast charging batteries are constructed with heavy load components due to excessive heat treatment. Therefore, it is important to carefully adjust the size of batteries and chargers according to power consumption research. Fast charging batteries usually have to be equalized for 6 to 8 hours a week to reduce sulfate content.
3. Opportunity charging
Opportunistic charging is what its name implies, that is, charging the forklift battery when it is convenient and possible (such as lunch break). Similar to traditional charging opportunities, charging helps to greatly reduce forklift downtime and avoid the need to purchase multiple batteries per shift. Opportunistic charging is an ideal choice when it needs to be used for a long time. With today's modern technology, the equalization and cooling periods can be adjusted to less than 8 hours, but the battery must be carefully monitored to ensure that the charger does not charge the battery slowly during peak hours.
