The Challenge

The electric milk powder bottle is a newly developed product by LeBaby Company to assist in adding and measuring milk. Because the previous battery supplier was unable to meet the needs of LeBaby’s electric milk powder bottle in terms of battery power, capacity, and supporting wireless charging modules. After comparing multiple lithium battery suppliers, LeBaby chose Ufine as the battery supplier for electric milk powder bottles to solve this technical problem.

Finding a Solution

After Ufine’s battery engineers received LeBaby’s electric milk powder bottle that was not working properly, they conducted an analysis of the cause of the problem and specially customized a lithium battery solution suitable for this product after a research meeting with the technical team.

1.The main reason for the phenomenon of the electric milk bottle getting stuck when starting up may be that the battery PCB takes a protective action at the moment when the motor is started, causing the battery to be unable to continue output, thus causing the motor to get stuck.

Ufine’s battery engineer used an oscilloscope to test the battery and captured the maximum peak operating current and peak time. Then compare the current and peak time to determine the battery protection circuit parameters. After modifying the configuration, the motor no longer jammed.

2. The main reason for the insufficient battery life of the electric milk powder bottle is the rate of the battery core, that is, the discharge capacity design is unreasonable. When the electric milk powder is working, because the current is too large and the battery rate design is not enough, the voltage drops more, causing the voltage to be lower than the working voltage of the motor, and the motor will stop working. But there is still more than 20% capacity in the battery that can not be used.

Therefore, UFine’s battery cell engineers designed a battery that can discharge at a rate of 3C but maintain the same capacity. After a series of tests, the overall working time of battery discharge was increased by more than 50%. Thanks to the increased battery rate, battery energy can be used better without increasing the cost.

3. The wireless charging speed is too slow. The main reason is that the wireless charging working rate is too small. Because previous batteries could only meet 0.2C charging, the charging circuit was designed to take more than 5 hours to charge. The lithium battery improved by UFine can be charged at 1C to 2C. After changing the charging module, the battery can be fully charged in 1 to 2 hours.
