AUTOMATIC NEGATIVE PULSE DESUFLATION BATTERY CHARGER

 

Charging stages and featured technology

Our negative pulse battery charger is completely different from conventional chargers you may find in market. The negative pulse technology helps reducing battery internal impedance while charging. The battery gassing amount is also only 10%-13% of that on battery charged by normal chargers. Temperature raise of battery while charging is also greatly lowered.

Our charger applies advanced charge algorithm. The negative pulse will maintain and equalize battery cells during the entire charging process. Unlike normal charger, which equalizes cells simply by increasing charging voltage after floating phase. However, our negative pulse charger will lift the cell voltage which are lower than average and lower the ones higher. Thus avoiding higher voltage which bring hazard of over-charge and gassing.

 

The basic charge stages:

1.     Initial testing

Our charger generates negative pulse to check the current receptivity of battery.

2.     Soft charge

Starting phase for charging. The starting phase continues until the battery¡¯s terminal voltage has risen over a preset level. At this point, charging goes into the bulk phase. If the terminal voltage has not reached the preset level within a preset time. Charging is suspended. The error mode is indicated. If a large battery is charged that has been severely discharged, it may be necessary to start the charger after a preset time.

3.     Bulk charge

Primary charging where approximately 80% of the charging takes place. The charger delivers maximum current until the terminal voltage has risen to the preset level. Our charger will monitor the battery voltage. Bulk current will be transferred to enable efficient charge if the battery voltage is under the gassing voltage.

4.     Absorption charge - high voltage constant

Voltage is kept at the preset level .During this phase, the current is gradually reduced. Gassing voltage may be exceeded in this phase. Our charger will increase the amplitude and frequency of negative pulse to ensure the minimal gassing amount.

5.     Test

Charging is suspended for a short period and the battery voltage is measured . If it falls rapidly, the battery is probably faulty. Charging is suspended and an error is indicated.

6.     Float charge - low voltage constant

Voltage has dropped to preset level with controlled current.

7.     Replenishing charge ¨C pulse

State of charge varies between 95% and 100%. The pulse charge is safety replenishing the last 5% of the battery¡¯s charge in a minimum amount of time.

8.     Maintenance

    The battery receives a pulse when the voltage sinks, keeping the battery in good shape when it is not being used. If the battery is charged and/or the battery¡¯s terminal voltage drops, the charger starts a charge pulse until the voltage has reached the preset level.  The charger pulse is then interrupted and the cycle is repeated as long as the charger is in pulse maintenance phase. If the terminal voltage drops even lower, the charger automatically reverts to the begging of the charging

9.     Desulfate

Batteries often fail because ¡°sulfates¡± slowly develop and cover the battery plates. This sulfating process also weakens the electrolyte and this combined with the gradual coating of the plates slowly and almost imperceptibly reduces the battery¡¯s ability to receive, store and then deliver power. This sulfating process gradually impairs battery function and causes a capacity loss until the battery can no longer perform the desired task and so the battery is deemed to have ¡°failed¡±. However using an Auto Pulse Battery Desulfator can reverse the process by dissolving the sulfates, cleaning the plates and restoring the electrolyte strength so improving a battery¡¯s life and capacity for an extended period.

 

FUNCTION

The High-frequency Peak Pulse delivers an electronically controlled pulse to the battery causing crystalline sulfates to dissolve back into the electrolyte and so restoring battery function and electrolyte strength regaining the batteries ability to receive charging current and deliver discharge current.
