DESC:FIELD OF THE INVENTION

The present disclosure relates to a zeta battery charger that charges the battery and discharges into the grid source which saves energy and cost of devices required.

BACKGROUND OF THE INVENTION

The demand for renewable energy sources has increased over the past few years, due to concerns regarding environmental sustainability and energy security. However, one of the main challenges with renewable energy sources, such as solar and wind power, is their intermittent nature, which can lead to energy wastage and reliability issues. To address these challenges, energy storage systems, such as batteries, have been developed to store excess energy when it is available and release it when needed.
Conventional battery chargers typically charge batteries from a power source, such as a solar panel or the grid. However, these chargers can be inefficient and can cause fluctuations in the grid voltage. Moreover, in some cases, excess energy stored in the battery cannot be used effectively.
To address these issues, a new type of battery charger called a Zeta battery charger has been developed. A Zeta battery charger is designed to charge a battery using a unique charging algorithm that maximizes the battery's charging efficiency and minimizes grid voltage fluctuations. In addition, a Zeta battery charger can discharge energy from the battery back into the grid when the grid demand is high, which can save energy and reduce the cost of devices required for energy storage.

In the view of the forgoing discussion, it is clearly portrayed that there is a need to have a zeta battery charger.

When Lead acid Battery manufacturing companies make a battery in a factory, they need different stages of battery charging and discharge logic at the nominal temp. 27*c , Battery gravity only maintain when battery charge, charge the fresh battery as per chemistry of lead and red oxide and gray oxide which is using in battery manufacturing. In an exemplary implementation, suppose battery manufacturing company has manufactured 150AH Battery and they require following charging profile
1) first battery charge 7a for 30 minutes, after 30 minutes battery would be charge from 21a for 4 hours, after that battery would be charge for 27A for 6 hours
2) After that the battery would discharge by 40A for 4 hours. Then again they want to charge batteries from 30 a to 6 hours , after that battery would be charged from 21A for 2 hours.
like that different customers want different charging profiles. up to 20 steps in one charging profile. battery manufacturing company want same time of profile for different AH of batteries
Accordingly we have designed a zeta battery charger in which 5 types of batteries chg profile.
Existing charger has only one charging profile. First charge the battery from CC (Constant Current) then CV (Constant Voltage) , in CC (Constant Current) mode charging current is fixed for all stages of charging. While the present invention charger has different stages of Charging, For CC (Constant Current) it is 0 AMP TO 40AMP and For CV (Constant Voltage) mode it is (12 Volt to 18 Volt PER BATTERY) .

Technical advantage- when we discharge the batteries , The stored power of batteries will be fed to the grid so that electricity demand reduces BY THE ENERGY METER and customers can save the electricity bill.
Inverters work with a parallel of the grid source as ongrid inverters work to export solar power to the grid, no one company is manufacturing a charger with grid tie logic.
