Distinctive features of forming charge and diagnostics of new storage batteries by V. Dankov method

Technical possibility of significant increase of a resource of reliable operation of chemical power sources according to V. Dankov Method for 12V lead acid storage batteries of all known standard sizes and variants of destination in a range of nominal capacities from 50 to 1350 Ah:

  • performing forming charge and diagnostics of new freshly formed storage battery
  • performing restorative maintenance and diagnostics of freshly charged storage batteries in service
  1. The main problems that successfully solving by using the methods of V. Dankov:

1.1. An enterprises manufacture batteries do not ensure the achievement of the maximum possible full charge of batteries supplied as part of new batteries which prevent a possible destructive overcharge.

ACTIVITIES to consumers of lead-acid batteries of all known types and variants of a target designation

Let’s consider the main reasons for the absence of the possibility to ensure high reliability of the storage battery operation using all currently known methods and means of maintenance of chemical current sources.

The widespread mass application of materials from the recycling of recycled storage battery as raw materials for the manufacture of new batteries leads to the possibility of various impurities, the presence of which according to GOST, DSTU for the production of storage battery is strictly limited or even excluded.

Such position leads to impossibility to provide a normal level of uniformity of initial value of given capacity in one batch of release of the same type accumulator blocks.

The technical possibility of significantly increasing the resource of reliable operation of chemical current sources

For all chemical current sources in modern technology well known that with an increasing in the discharge level (especially below 50% of the capacity) crystal-like hardly soluble discharge products are formed in the composition of the surface and deep layers of the active mass of the plates. The more such formations accumulate in the active mass then more difficult to charge fully the battery which may lead to hardly predictable failures in the operation of the storage battery when the standard load is connected.

Attempts to solve this problem by conducting a preliminary deep discharge and then a full charge with an impulse current or by the other well known methods of charging were failed.

Search for the most optimal mode of operation of the individual battery charger of high-voltage battery consisting of Li-ion modules.

Search for the most optimal mode of operation of the individual battery charger of high-voltage battery consisting of Li-ion modules.

1 stage

1st step or Iz1 = 0.024 Cnom

or just Iz1 = 1.5A

2nd step Iz2 = Iz1 + d*Iz1 n

where ( d*Iz1 ) or 0.005 Cnom or 0.5 A

About technical possibility of significant increase of reliable work and double increase of a stock of accident-free service of stationary glandular storage batteries in regions where an ambient temperature range from +10 to +55 °C and where access of the maintenance personnel is difficult or limited. Where the only power source is a solar panels.

Preparation for commissioning of new storage batteries. Selection and restoration of battery cells for the purpose of verification of their further use.

Initial conditions:

  • New 2V battery cells are jelly-like one batch and one factory of the manufacturer. They may be kept at rest for varying periods of time.
  • The battery cells that were in service can be different manufacturers, different production times but necessarily of the same denomination.
  • In the charging-discharging group either only new or only was in service.

Techniques for conducting a forming charge and diagnostics of new 12 V lead-acid batteries

Techniques for conducting a forming charge and diagnostics of new 12 V lead-acid batteries (of all known standard sizes and destination options in the range of nominal capacities from 50 to 1350 Ah).

  1. The main problems that successfully solving by using the methods of V. Dankov:

1.1 An enterprises manufacture batteries do not ensure the achievement of the maximum possible full charge of batteries supplied as part of new batteries which prevent a possible destructive overcharge.

At the same time among the batteries in the new storage battery can be a high level variations in the values ​​of their characteristics.
