LG E78 2S12 Modules FAQ

Q: What's the nominal voltage of LG E78 modules?
A: Nominal voltage is 7.4V per module.

Q: Recommended cooling methods for LG E78?
A: Liquid cooling is strongly recommended.

Q: What BMS integrates easily with LG E78?
A: Compatible with Orion BMS systems.

Q: What is the pinout for the LG E78 2P12S Module I/O harness?
A: The 22-pin connector pinout is:

Q: What is the recommended torque specification for fastening the power terminals?
A: The recommended torque for the M6 bolt used on the power terminals is 9 Nm ±10%. Always ensure that the terminal surfaces are clean and free of foreign substances before assembly.

Q: How should the module be handled during transportation and installation?
A: The module must be handled using specific gripper interfaces located at pre-defined positions. It's essential to avoid transporting the battery by non-designated points to prevent damage or dropping.

Q: Is the module waterproof or dustproof?
A: No, the module itself is not waterproof or dustproof. Adequate protection must be provided at the pack level to prevent issues such as condensation or water ingress.

Q: What are the minimum spacing requirements between modules in a battery pack?
A: A minimum clearance of +10 mm (without planned changes) or +15 mm (with planned changes to EVO) between modules is necessary to accommodate swelling and prevent mechanical stress.

Q: What are the cooling requirements for the module?
A: The module is designed for indirect cooling through its bottom surface. The recommended cooling interface area is 500 mm × 215.4 mm. It is crucial to ensure the cooling surface is clean before assembly to maximize heat transfer efficiency.

Q: What are the insulation resistance and voltage inspection specifications?
A: Insulation resistance is specified as 600 MΩ (500 V for 60 seconds), and the dielectric voltage inspection specification is 2.5 kV DC.

Q: What is the recommended assembly force and allowed acceleration for module manipulation?
A: Allowed assembly force per interface is 3 kN (X, Y, Z directions), and the allowed acceleration is up to 3 g, with a maximum acceleration of 5 g.
