AMPTRON® Battery Cell Safety Features and Design
The main issue with all lithium batteries is how to prevent a cell from overheating and rupturing if over charged. AMPTRON® Batteries have several layers of safety redundancy systems at the cell level. The most notable safety feature in our latest cell design is the internal thermal fuse between the anode and cathode that will shut down the cell before the temperature rises. If the thermal fuse protection is to fail, the electrolyte has a flame retardant additive making the battery safe. These conditions would likely occur if a charger or controller failed and inducing spiking current into the battery. The BPS is designed to protect the cells from this anomaly and would have to fail in the closed state allowing excess current into the cells. Most of our batteries are built with Prismatic 3.2V cells, all cells are matched by measuring several consistencies during several charge / discharge cycles at the end of cell production & before the battery assembly process begins.
CELL BALANCING
The Built-in Battery Protection System (BPS) balances the cells by sending more current through the length way circuit boards and into cells with a lower voltage. The BPS will also discharge cells that exceed 3.65V during charging.
BOLTED CELLS
Most cells positive and negative terminals are bolted vs the more common tab welded method. This creates a better connection for higher amperage loads and better current conductivity
CIRCUIT BOARD
The AMPTRON® Circuit Boards have a unique function of over current protection. The cells bolt through AMPTRON® circuit board that provide balancing, even current flow, short circuit protection adding rigid mechanical strength to the battery pack.
CIRCUIT PROTECTION
If a cell overheats or if the battery is penetrated by a metal object the AMPTRON® Circuit Board will disconnect the cells output voltage to the battery main terminals.
