Performance Analysis of Lithium Polymer Pack and Lithium Ion Pack Batteries With Load Variations

Batteries are the main device in electronic devices. Batteries have developed rapidly to become the main energy source for modern vehicles, namely electric cars. Lithium-ion batteries are lithium batteries with electrolytes in gel form inside. This battery is widely found in everyday life because it has one of the best energy densities, has no memory effect, and experiences a slow loss of content when not in use. Lithium polymer batteries are different from lithium ion, lithium polymer batteries use dry electrolytes in the form of layers and layers. A data logger is a monitoring system designed to store and monitor real-time data in the form of voltage, current, and time. The performance of the 48 V 6.6 Ah polymer lithium battery pack against varying 5A current loading results in an average current usage of 5.03 A. The temperature rise that occurred during the test with 5A current was 1.10°C and the battery experienced a power loss of 25.7 watts. The performance of a 48 V 6AH lithium-ion pack battery against a 5A current loading variation resulted in an average current of 5.03 A. The temperature increase that occurred during the test with a 5A current was 5.8°C with a residual voltage of 44.27 volts. Tests that have been carried out show that the battery will experience a faster and greater discharge when the discharging capacity is also high. The polymer lithium battery shows a decrease in intensity of 39 watts when tested with a variation of 7A current and the capacity used is 3.65Ah. The lithium-ion battery shows a power reduction of 68.7 watts with a used capacity of 3.51 Ah at 7A of varying current loading
