In recent years due to the rise of new energy concept, lithium battery car air was pushed to the fore, due to its characteristics of environmental protection and energy saving had a lot of customers, but by the popularity of charging equipment, restricted range, driving regional guangyuan uncontrolled, the influence of such factors as the current most lithium electric car applies only to commuter car, electric car maintenance, Sanitation vehicles and short – line buses and so on. However, many forklifts operate mostly in the factory area, the working intensity and environment are fixed, and the working intensity is generally strong. Therefore, many advantages of lithium batteries can be reflected in electric forklifts.
Compared with lead acid, nickel-cadmium and other large batteries, lithium-ion batteries do not contain cadmium, lead, mercury and other elements that may pollute the environment. When charging, it will not produce “hydrogen evolution” phenomenon similar to lead-acid battery, will not corrode wire terminal and battery box, environmental protection and reliability. Iron phosphate lithium ion battery life of 5 to 10 years, no memory effect, no frequent replacement. The same charging and discharging port, the same Anderson plug solves the major safety problem that the forklift can operate when charging caused by the different charging port mode. Lithium ion battery pack has intelligent lithium battery management and protection circuit -BMS, which can effectively cut off the main circuit for low battery power, short circuit, overcharge, high temperature and other faults, and can alarm the sound (buzzer) light (display), traditional lead-acid battery does not have the above functions.
It should be emphasized that the difference between lithium-ion forklifts and traditional electric forklifts is not just about replacing batteries. Xin work motivation yuanyuan told reporters that the lithium ion battery and lead acid batteries are two different systems of power battery, the battery on the same principle also not too, lead-acid battery forklift instead of li-ion battery forklift truck is not a simple battery switch, it involves a set of complete system matching and technical support, is a kind of new technology and structure of the transformation, Need to have enough technical reserves and experience accumulation to achieve.
As an electronic component of real-time monitoring, automatic balancing and intelligent charge and discharge, battery management system plays an important role in ensuring safety, extending life, estimating remaining power and other important functions. It is an indispensable part of power and energy storage battery pack. It ensures the safe and normal operation of batteries and vehicles through a series of management and control. In terms of normal use of lithium battery, there is no problem, but even if the technical level of lithium battery is high, there are also very small safety risks, such as leakage or even explosion of lithium battery in the case of improper use.
Lithium-ion batteries are only a quarter the weight and a third the size of equivalent lead-acid batteries. As a result, the mileage of the vehicle can be increased by more than 20 percent under the same electric charge, and the charging efficiency of the lithium-ion battery is more than 97 percent, while the efficiency of the lead-acid battery is only 80 percent. Take 500AH battery pack as an example, save more than 1000 yuan of charging cost compared with lead acid battery every year. Therefore, the development of forklift lithium battery is the trend.
