Charger SOROKA v.9-TOP automatic adaptive

Charger-recovery device Version 9

When developing the Version 9 charger, many years of real operating experience were used Version 6, Version 7, Version 8. Some Version 7 models today have over 16,000 hours of actual operation without failures or failures.

 

Changes have been made to the memory operating program based on the actual use of the pulse charge algorithms of the Memory Version 6 and Memory Version 8, which became possible thanks to the 16-bit Texas Instruments MSP430FR5972 microcontroller, which has 12-bit ADCs with a speed of 200 thousand samples per second, 16-bit timers with unique possibilities. This made it possible to raise the capabilities of the Version 9 charger to monitor battery parameters during charging to a new level, and the unique memory of FRAM technology made it possible to store more dynamic data. TOP250 from PowerIntegrations, Inc. is used as a power converter in this charger model. Charge currents up to 15A

 

The charger can work with 6V (lead) 8V (lead) 12V (lead) batteries and has a custom settings mode (*Hv). The changes concerned increasing the reliability of operation in high (10A-15A) current modes and optimizing the microprogram code. A specially designed power pulse transformer is used.

 

This charger contains a circuit for automatically measuring the internal resistance of the battery. For a description of the measurement algorithm, see the end of this manual.

 

Compared to our other chargers, the Version 9 charger takes into account the vast operating experience of Version 4, Version 5, Version 6, Version 7, Version 8, and the necessary corrections and improvements to the hardware and software have been made, aimed at increasing the reliability of the charger and supporting different pulse charging modes. Due to numerous requests, additional features have been added, namely: “pulse+CCCV” and “(zar)”, *Hv options with voltages up to 16.0 volts, for using this charger not only for battery recovery, but also for a more complete everyday charge.
 

Unfortunately, lead-acid batteries are not designed for fast and frequent charging with high current. Starter batteries are also critical to deep discharge. 

The “Version 9” charger can help partially solve the problem of accelerating charging, as well as slow down the process of battery degradation.

 

If you connect the Version 9 charger directly to the terminals of your battery, without disconnecting or removing the standard “charge classic” charger, you will receive a two-stage charge profile. 

The Version 9 charger is connected in parallel to the main source of charging current, which is your UPS or inverter, or a simple classic charger. When switching on in this way, you must select the STD mode; it is recommended to set the battery capacity to 7 Ah.

 

1st stage: when the battery is discharged, it runs at full current Your standard

The charger, and the Version 9 charger mixes its own pulse charge current, and there is no need to set large current values ​​in the Version 9 charger. Pulse mixing will be enough for faster absorption of charge by your battery.

 

Stage 2: will begin when the voltage on your battery rises above 13.0...13.5 volts.  During this period, classic chargers usually reduce the charge current, and your standard charger cannot support a higher charge current.

 

Charger Version 9 does not reduce the charge current when approaching 14.4 volts, which will allow your battery to charge faster at the final stage of charging. 

And this will be more of a pulse charge than a direct current charge, which will have a beneficial effect on the service life of your battery.

 

This mode was tested by us on several home power supply installations, and showed excellent results even on starter lead-acid batteries.

Address of the Author to Buyers and Users of Memory

 

Author's Message: Please remember that you purchased the Author's Charger, and not a “power supply”. A charger is a device that was originally developed for work on charging the battery and not “maintaining the required voltage with current limitation.” This purpose of the charger imposes certain restrictions and removes the “classical requirements” for stabilizing voltage and charge currents. This charger is the result of more than ten years of my work on charging and restoring lead batteries of all types. The charger uses proprietary charging techniques (algorithms) that differ from the generally accepted “classical” ones. It is based on two principles: “do no harm” and “do everything possible to quickly and efficiently charge the battery.” Years of work using the “adaptive pulse” charging method have shown its high efficiency in restoring the properties of lead-acid batteries of all types. Research work continues. This memory has many operating modes. The charger was designed not only as a “set it on charge and forget it” but also as a Tool for Researching Battery Properties. Therefore, in this charger, different charge settings are used and described below. You don’t have to use them all, but the charger allows you to provide you with maximum opportunities if you are interested in experimenting with batteries.

__ It should be remembered that it is impossible to accurately measure and display in the form of “so many amperes” currents of complex shape, and averaging methods sometimes introduce large errors, so the LCD in the memory displays current and voltage values ​​snatched from the “data stream”. I remind you that according to electrochemistry and GOST, the battery capacity, as well as the ampere hours given, can only be measured by conducting a Control Training Test (CTT) for an active load. All other methods are estimates of varying degrees of accuracy and approximation and are not officially recognized.

__ I kindly ask you not to use alligator plugs to charge the battery! They are now made of thin galvanized iron, they give high resistance at the point of contact with the battery, this can lead to heating, partial melting of the battery terminals at the points of contact, and at high currents (10A-15A, and in pulses up to 100A) developed by this charger, it is possible sparking due to poor contact. It is best to use a terminal connection with bolted wire crimping. Poor weak contact with the battery will lead to incorrect operation of the charger algorithms.

__ Do not extend the wires from the charger to the battery! The charger is equipped as standard with 4mm2 wires with a cross-section of 50cm. By increasing the length of the wires you lose all the benefits of pulse charging.

__ When the charger operates, it makes sounds. This is fine. In the basic mode (modulation “0”) the sound resembles a faint rustle, the volume depends on the charging current - the higher the current, the stronger the sound. When selecting other modulations, the sounds may resemble the “circular saw sound”; the higher the current, the stronger the sound. Please take this into account when operating the memory. The sounds arise due to the magnetostriction of the charger transformer core when working out the charging algorithm; it is impossible to completely remove the sound when the charger is operating. The transformer is filled with varnish with vacuum impregnation of the windings, but this does not help the silence.

__ The memory does not have an independent “standby power supply” for the processor part. This does not allow you to reduce the voltage below 4.5V to power the battery, keep this in mind.

__ By popular demand :) the following modes have been added to this memory: CCCV+Impulse and STANDART(zar), *Hv with voltage up to 16.0 Volts, their task is to provide a higher degree of battery charge, but while maintaining the recovery properties of the pulse algorithm. This is not an easy task, but I managed to find a solution. For a description of the modes, see below. I do not recommend using higher voltage to charge your batteries! It could kill them.
