Electric forklift Stacker Introduction and battery maintenance charger


Electric pallet truck forklift electrical infrastructure components for the motor, battery, controller, charger, DC converter, the management system. These major components determines the performance and development of electric forklifts. Here mainly talk charger role in electric forklift.
Knows charger is for charging the battery. But how charged the battery is fully charged to make and does not damage the battery, and what to do to effectively protect battery and prolong battery life, which can not be ignored.
Electric forklifts are now mostly used lead-acid or lithium iron phosphate, iron acid batteries, lithium battery price is quite high, a set of batteries cost about 10 million. If the battery replacement in advance, then it is a great loss, directly affects sales and credibility. This requires a good performance to the battery charger to service. If no good charger, battery charge discontent, running far ahead of replacement batteries, battery heat burning, etc., so the electric stacker forklift industry will lag.
Battery maintenance charger side and the maintenance is not a part to complete, but also requires a battery management system to manage. Effective management, timely detection of battery problems, solve the problem. Now many businesses are seeking fast charging, or caution, after all, expensive batteries. The best battery maintenance is the "shallow charge and shallow discharge."
Using the power of the commonly used frequency transformers (core, 50Hz) linear power supply and use high-frequency transformer (cores, thousands Hz) switching power supply two categories.
Switching power supply principle is: first frequency (50Hz) AC is converted to high-frequency current, and then goes through the high-frequency transformer output voltage after rectification low voltage DC. As with the power of the high-frequency transformer volume much smaller than the frequency ---- The higher the frequency, the smaller the size, so you can do big power, small size, light weight, they have been widely adopted. He is mainly regulated by controlling the oscillation frequency to achieve, because of this, switch power to do well in shielding the case if used for charging transmitter harmonic interference easily lose regulator performance, leading to voltage fluctuations, Due to its high-frequency interference or the frequency mutation. Also, if the switching power supply protection circuit do not, then, in the event of failure, the voltage may rise suddenly and burned a lot of battery. So right, there is a linear power supply should be some room for development.
People in their daily use of batteries in the process less prone to errors caused by related needs attention, in strict accordance with the requirements of battery operation, to prevent undue consequences.
A misunderstanding that battery maintenance. When using maintenance-free batteries. After charging excessive discharge is not timely, but also occasional supplement charge, so that the battery life is affected.
Myth, were coated with Vaseline. Pole device after connection. Make the connection joints severe oxidation, resulting in poor contact line, the circuit is unstable.
Myth, with pure drinking water instead of distilled water used. Added distilled water. Knowing that pure water contains many trace elements, have an adverse effect on the battery.
Myth, the density of the electrolyte does not differ by region and season to adjust. Especially in winter comes, resulting in lack of battery capacity. Minutes after the shake-crank the car. No matter what kind of first aid, first aid can only be used when on the way, traveling to the service point or resident, be sure to fully repair or replacement shall not reluctant to use.
Myth, uninterrupted access to the starter. Winter use battery starts. Cause battery damage due to excessive discharge
