Reading State of Charge From Forklift Battery Voltage

Many electric forklift operators and warehouse management staff are eager to master the skill of reading the remaining state of charge from forklift battery voltage accurately, which can effectively avoid unexpected power interruption during peak operation hours and reduce unnecessary work delay. It is important to note that you can not judge the state of charge only by a single instantaneous voltage reading, because the real-time voltage will show obvious fluctuation when the forklift is under heavy load, in the startup moment or working in low temperature environment, which will lead to large deviation of judgment. The more reliable operation method is to park the forklift on flat and stable ground, turn off all power consuming accessories including the lighting system and hydraulic operating system, and leave the battery standing for 15 to 30 minutes to reach a stable open circuit state, then read the voltage value for SOC reference. For most common forklift batteries on the market, the open circuit voltage has a relatively stable corresponding relation with the remaining state of charge within the conventional working range. You can record the corresponding voltage values at 100%, 75%, 50%, 25% and 0 state of charge when the battery is fully new, and summarize a set of practical reference rules suitable for your own equipment after multiple verifications. As the battery is used for a long time, the performance of the internal active material will decline, the corresponding relation between voltage and SOC will also have deviation, so it is recommended to correct the reference data every 3 to 6 months, to ensure the accuracy of judgment.
