Tesla Model 3 Square Hard Shell LiFePO4 Phosphate Cells: Detailed Research & Specifications

This battery comes from the Tesla Model 3 produced in December 2020.It has a total energy of 55 kWh and is composed of two 25-series 1-parallel battery modules and two 28-series 1-parallel battery modules.

The battery uses CATL's LFP6228082-161Ah square LFP battery.

Its specifications are as follows:

nominal capacity 161 Ah
rated voltage 3.2 V
internal resistance ≤ 0.4mΩ
weight approximately 3.1 Kg

Sandro Stock and others from the School of Engineering and Design at the Technical University of Munich in Germany decomposed and studied the square hard-shell lithium iron phosphate battery used in Tesla Model 3 and published a report《Cell teardown and characterization of an automotive prismatic LFP battery 》
