The Truth About Lithium Battery Nominal Voltage in Forklifts

Many forklift operation and maintenance personnel often feel confused about the lithium battery nominal voltage marked on the product housing, and many people mistakenly take this parameter as the real-time working voltage of the battery, which leads to a series of improper operation behaviors that reduce battery service life. In fact, the lithium battery nominal voltage of forklift is a unified rated reference value specified in the industry standard, which is calculated by summing the nominal voltage of all single lithium cells connected in series in the whole battery pack. This parameter is not equal to the full charged peak voltage of the battery, nor the cut-off voltage when the battery is completely discharged, it is designed to match the electrical system of the corresponding model of electric forklift, to ensure that the output power of the battery can fully cover the demand of driving, handling and other working conditions. Different tonnage of forklifts match different nominal voltage specifications of lithium batteries, blindly using batteries with non-matching nominal voltage will cause extra load on the motor and controller of the forklift, which may bring potential safety risks. Many industry practitioners have wrong cognition that the higher the nominal voltage is, the longer the battery lasting time will be, which is not correct, the endurance performance of the battery is also related to the battery capacity, the quality of the battery management system and the actual working condition load. Correct understanding of the nominal voltage parameter can help enterprises arrange battery charging and maintenance plan more reasonably, reduce unnecessary loss, and extend the whole life cycle of the equipment. Professional new energy service provider Jianshu New Energy can provide scientific lithium battery voltage matching solutions for different application scenarios, and also support the adaptation service that matches the product system of BYD Forklift. If you have technical consultation demands about forklift lithium battery nominal voltage configuration, maintenance or daily use guidance, you can send your specific demands to 17399989919@163.com for professional reply. It is worth noting that any modification of the battery pack nominal voltage without professional qualification violates relevant safety operation specifications, and must not be implemented without permission. In daily use, operators should not judge the remaining power of the battery only according to the nominal voltage value, they should refer to the data fed back by the on-board battery management system, arrange the charging plan reasonably, so as to ensure the long-term stable and efficient operation of the electric forklift fleet.
