What is the correct charging method for the forklift battery

Forklift battery as a forklift, tractor, truck, underground mining locomotive, and other equipment dc power supply, widely used in airports, stations, ports, vegetable and fruit markets and industrial and mining enterprises warehouse and other places. Forklift battery refers to the battery used for forklift operation. That is the battery in the battery of the electric forklift. Today, I will introduce the correct charging method of forklift battery:

1. Preparation before charging the forklift battery

1) form the battery pack in series to ensure correct polarity and reliable connection.

2) pour the prepared electrolyte into the battery, and the liquid level should be visible at the bottom of the flower basket inside the plug.

3) let stand for 4 to 8 hours, depending on the temperature to be inside the battery electrolyte temperature drops below 35 ℃ can charge. (charging in flowing water tank is the best when conditions permit)

4) connect the positive and negative electrodes of the battery pack with the corresponding positive and negative electrodes of the charger output reliably.

2. Forklift battery charging and charging current selection

1) the first charge shall be carried out in two stages:

Ⅰ phase: in 10% of the capacity for the charging current. (example: d-500 = 500 x 10%=50A); Voltage is set to (2.5 x battery number only) V, when the charge to single voltage of 2.4 V to the Ⅱ stage; (this stage usually takes 20-30 hours)

Stage II: 1/2 continue to Ⅰ stage of charging current charging (500 x 10% present 2 = 25 a) until the filling the power 4.5 5 times of the rated capacity.

Please refer to the following methods to determine whether the charging is complete:

At the later stage of battery charging, the measured voltage does not rise for 3 hours without changing the charging current.

Late b battery, the electrolyte density for three hours don't rise, and 1.270 + / - 0.005 g / ┩ (liquid level height standard).

C the electrolyte liquid level in the battery produces violent and uniform bubbles.

2) ordinary charging, namely charging after use, is carried out in two stages :(this stage takes a total of 12-16 hours)

Stage I: 14% of the battery capacity is taken as the charging current (e.g., d-500, i.e., 500 * 14%=70A). When the voltage of a single battery is charged to 2.4v, it is transferred to phase II.

Phase II: continue charging at 1/2 of the charging current of phase I (i.e. : 500 14% 2=35A) until the charging amount is 1.4-1.5 times of the discharged amount, and refer to section a, b and c in 3.1.

Note:

(1) the first charge should not choose constant voltage charger charging.

(2) the first charge must make the battery to complete the full power state.

(3) in the process of charging, make sure the temperature within the 55 ℃, if more than should reduce current or stop recharging after cooling.

1. The charge

Forklift maintenance when the battery has been discharged 80%, need to be charged in a timely manner, to avoid excessive discharge of the battery, resulting in shortened service time of the battery.

2. Charging time

General automatic mode charging time is 10-12 hours; The charging time in equal mode is 12-15 hours.

3. Charging method

For the maintenance of Chinese forklift, the seat cover should be opened first. For the maintenance of forklift, the battery door should be opened first, and then the charger should be connected with the battery plug to ensure the connection is in place.

4. After each charge, press the stop button before disconnecting the plug.

5. The selection of the charging station must be under good ventilation conditions.

Two, maintenance method

1. Use a damp cloth to remove dust from the surface of the battery at a specified time.

2.1 check whether the battery buoy is in the white area within the specified time within a week. If it is found that the battery water is too little, distilled water should be added. The added amount is 2/3 of the exposed white area of the buoy, and ensure that all the bouys cannot surface.

3. Check the battery plug regularly and replace it even if it is found that the copper connector of the plug is burnt or the plastic shell is damaged

The performance of the forklift battery will directly affect the use of the electric forklift. The daily inspection and maintenance of the battery should be carried out in strict accordance with the specifications. The following is a detailed explanation of the battery maintenance rules for the forklift.

Daily maintenance

The battery should be charged immediately after each discharge

Each discharge shall not exceed 80% of the total capacity of the battery

Weekly maintenance

Check whether the cable screws between the battery units are fixed

If the battery is not equipped with an automatic charging system, check the height of the electrolyte after charging. Below the allowable level (isolation plate height or specified height), add qualified distilled water to the specified height. In case of excess electrolyte, extract to a specified height

Check whether there is water inside the battery box, and if there is water, please blot it out immediately

Monthly maintenance

Before the end of charging, check and record the voltage of all electrode units and batteries

After charging, the electrolyte density and temperature of each cell should be measured and recorded. If there is a significant difference from the previous measurements, it should be checked by a professional

Annual maintenance

The insulation resistance of the forklift and the insulation resistance of the battery shall be inspected by professionals once a year. The insulation resistance of the battery is rated at 50 ohms/v. For batteries rated at 20V, the resistance shall not be less than 1000 ohms

Check the charger according to the instruction to ensure all functions are normal

General considerations

The battery should be kept clean and dry to avoid leakage current

If there is any liquid in the battery box, it must be sucked out immediately by a straw

If there is any damage to the paint of the battery, it should be repaired immediately to protect the insulation of the outer box from corrosion

If it is found that the battery unit needs to be replaced, it should be carried out by a professional

Storage of battery

Storage batteries should be stored in a dry, frost-free place

If the battery can be put into use at any time, it should be processed as follows

A monthly compensation charge is carried out at an average charging voltage of 2.23v per cell

Please note that too much storage time will affect the overall battery life
