The DC system is mainly composed of rectifiers and batteries. Among them, the role of the battery pack is particularly important. In the event of a grid failure, the load will be supplied directly by these battery packs, which is the last barrier to the DC system.

The closed valve-controlled lead-acid battery has outstanding advantages at the same time, but also brings inherent deficiencies, such as:

1, The battery is difficult to test capacity and cannot add water, which also need high the floating charge voltage and the use requirements and so on.

2. After the battery is put into use, due to factors such as the design, tooling equipment, quality control and other factors before the battery leaves the factory, as well as the floating charge voltage setting in use, the ambient temperature used, etc., it will lead to the phenomenon of active material falling off, deterioration, positive grid corrosion and vulcanization, which will cause the entire group of batteries to lose capacity, uneven voltage difference,  single batteries fault and etc.

This will bring great hidden dangers to safe production, when the power grid failure and  requires battery power, the battery cannot discharge the vicious accident, therefore, the maintenance procedures require the battery to carry out a check capacity test, the purpose is to test the actual capacity of the battery pack, find out the fault battery, eliminate hidden dangers.

Then the problem comes out, and the problems that TOMSON need to solve for battery maintenance in the actual work process can be summarized as:

1: Daily maintenance and testing of the battery to find out the unqualified or invalid battery.

How to check?  Experience alone?  No,

The professional "DFT-6101 battery internal Resistance Tester" will be your daily maintenance and detection of the right assistant, can help you find out the invalid battery by testing the battery's internal resistance and voltage, preliminary estimate of the battery capacity. This solves the problems of capacity testing and daily effective grasp of the battery state, checks out the invalid battery, so as to achieve the state of the battery at any time.

2: Must the detected invalid battery be unqualified or discarded? Not always, in fact, there are still many batteries that can be repaired and reused,

According to the Battery usage rules: new and old cannot be mixed, different brands and different batches cannot be mixed, so that the activation of a battery to achieve the effect of saving a group of batteries. The implementer of this function is the professional "DFT-6900 smart Battery Activator", which solves the repair problem of ineffective battery.

3: After daily maintenance and activation, TOMSON will also carry out annual check and discharge inspecti0ooin of the battery very accurately according to the regulations to determine the capacity and status by "DFT-6300 smart battery discharge monitor as Load Bank" in this complete set of products to complete this work.

4: These are the testing instruments in the process of regulations and daily maintenance, have you ever thought about the impact of the charger on the battery? What happens to our battery if the ripple coefficient and voltage stabilization accuracy of the charger do not meet the requirements? It is dry, swollen and even bursting. So the general manufacturers ignore this source, but TOMSON did it, I have a professional instrument to test the charger to test the quality of the charger, so from the source of charging to achieve the maintenance of the battery. This will rely on the "DFT-8800 DC System Comprehensive Characteristics Tester" to check.

In addition to the products introduced above, the TOMSON also has many professional instruments to test and maintain the battery. The TOMSON's battery maintenance series products make the traditional battery capacity test and maintenance from cumbersome manual operation and manual detection data to the smart automatic test record data of microcontrollers and microcomputers, which will greatly improve the accuracy of the test, reduce the workload of maintenance personnel, improve work efficiency, so as to eliminate hidden dangers and ensure safe production.
