Battery Inspection
Cracks
These modules are prone to cracks if mishandled, dropped, or due to manufacturing defects. herefore, inspect them for these obvious defects.
Electrolyte Leaks
The battery can often leak due to mishandling or manufacturing defects, leaving a prominent white mark or visible liquid bubbles on the casing.
Cleanliness of the heat sink
The walls of the battery serves a dual purpose: dissipating heat generated within the cell and maintaining the battery’s structural integrity. It is crucial that the aluminum wall is clean and free of obstructions during assembly to ensure optimal performance
Broken Ground Screws
The battery ground screw is used to attach the battery to the frame. Sometimes, due to cross-threading or over-torquing, it can break. If this happens, the broken screw must be removed to properly ground the battery module and ensure overall safety.
Threaded Terminals integrity
If the nut is improperly installed, it can damage the threads, necessitating the use of a tap and die set to rethread it
Interlocking Mechanism
Improper packing of the battery can damage it. The protruding part of the interlock may push against the battery wall and potentially puncture it.
Identify Battery Module Parts
Terminals
To connect the battery in a pack.
Safety Valve
This will release the electrolyte gases in case the pressure inside the cells exceeds the limits.
Ground
This is located in the bottom and is used to secure the module to the frame and additionally serve as the ground.
Temperature Well
Used to measure the temperature of the module in a test setting or when assembled in a pack.
Heat Sink
Alluminium casing on the either side of the module is meant to dissipate battery heat.
Interlocking Mechanism
Interlocking mechanics is provided to lock the battery modules for efficinet ventilation and structureal integrity.
