Storage Battery Online Performance Balance System ( Cabinet type )

1, Patented product with balance online. 2, Activation and detection technology to prolong and improve batteries.

Chemfree DC Power System Group devotes itself in providing energy-saving solutions to stations of communications, power plants, etc.

CBE200 series products of batteries online  balancer were  firstly  introduced  in 2006.

The product solves unbalance of battery monomers during operation, meanwhile, batteries with low performance can be activated online so that its service life can be doubled. Online internal resistance test and capacity test for battery are also provided to enhance the reliability of battery operation.

Application of battery

Balance online: adjust voltage, internal resistance and capacity of each battery to a balanced state so as to prevent battery monomers from being overcharged or undercharged, by which the consistent performance and optimal operation state of batteries can be ensured.      

Activation online: activation online can be conducted to battery monomers with weak performance to protect it from sulfation due to long time floating charge.      

Testing online: it provides online testing for internal resistance, capacity, terminal voltage and online activation of battery, which can completely take place of the internal resistance tester, capacity tester and voltage inspection device of batteries in the existing DC power system. It also provides a comprehensive and perfect solution for the operation of  battery–powered device, greatly enhancing the reliability of the operation, thus becoming a novel product.

The balancing result is obvious, and the consistency is increased enormously.

  

On April 27, 2009, the measured batteries balance degree (consistency) of 48V/200AH batteries was 10.4 after CBE 200 series batteries balance online device was applied in the central substation in the Electric Power Bureau of a certain city.

On April 30, 2009, the second measurement of 48V/200AH batteries was taken after the CBE200 series batteries balance online device was applied, and the batteries balance degree (consistency) rose to 1.1.

Left picture (polar plate of lead-acid battery): the first picture displays the massive sulfate crystallization. And the discharge time only lasts for about 13min when full discharge test was carried out.

Right picture: this is the picture of the same polar plate, but the plate has been installed with CBE 200 series batteries online device for 18 days. It can be shown that the sulfate crystallization has been eliminated, and the discharge time lasted for 33min, meaning that discharge capacity increases by 250%.

Left picture (lead sulfate crystal micrograph): battery plate is massivelycovered by lead sulfate.

Right picture: lead sulfate crystal has been cleared away by activation technology and the active material of battery polar plate has been revealed after the application of  CBE200 series batteries balance online device.

Characteristics of CBE200 product
