After a very short time, The AC supply will produce a volt that is higher than 3 volts because it swings between 0 and 5 volts. so, the AC supply voltage will be higher than the DC battery voltage. As a result, Current will move from AC supply to DC battery and that will consume more power and damage your DC supply.

motor controller requiring a battery in parallel with DC power supply
"If a power supply that cannot sink current is being used (example: bench top and AC to DC switching power supply), the input voltage will rise when the driver is regenerating (motor is slowing down). Thus, it is important to connect a battery with same voltage in parallel with the power supply to absorb the current generated by the motor.

View more6 FAQs about [Principle of DC battery pack parallel power supply]
Why does a battery pack need a series and parallel connection?
This combined setup is necessary because relying solely on one method may not meet the power requirements. By combining series and parallel connections, battery packs can be customized to deliver the desired voltage and capacity. For simplicity, battery packs are labeled with abbreviations : “S” for series and “P” for parallel.
What is a parallel battery connection?
Parallel connections, on the other hand, increase the battery’s capacity, making them perfect for applications requiring longer runtimes or greater energy storage. In most cases, a combination of both series and parallel configurations is used to create a powerful, stable battery pack with the necessary voltage and capacity.
How do I add more batteries in parallel?
If you want to add more cells in parallel, connect the positive terminal of the third cell to the positive terminals of the others, and do the same with the negative terminals. This configuration increases the overall capacity of the battery pack without changing the voltage.
How to parallel EA programmable bidirectional DC power supplies?
EA's programmable bidirectional DC power supplies are easily paralleled using Cat-5 cable (for communications) and BNC cable for current sharing. Step 1. Physically parallel the +/- outputs Step 2. Connect the Share bus to ensure units are sharing current equally Step 3. Connect the master/auxiliary bus to ensure communication between the units
How are battery connections made?
Battery connections can be made in two fundamental ways: series and parallel. These methods refer to how multiple battery cells are connected to meet the power requirements of various devices. Typically, a single battery cell cannot fulfill these needs.
How do you connect two batteries in a battery pack?
It involves connecting the positive terminal of one cell to the negative terminal of another. To connect additional cells in series, continue connecting the positive terminal of the second cell to the negative terminal of the third, and so on. This process increases the overall voltage of the battery pack.
