ニチダイフィルタ List of Products and Services

This is a battery tab integrated with a busbar using unique diffusion bonding technology. (Cu < Ni plating > + Ni hybrid tab) The resistance value can be reduced by approximately 70% compared to conventional Ni tabs. *The resistance value is lower than that of pure Ni products because it passes through Cu during discharge. Features: Performance Benefits - Usable for larger drive systems - Thickness can be changed as needed - Use of Cu in the busbar → significant reduction in resistance - Flexible response to various designs Manufacturing Benefits - No projection required - Thin tabs allow for stable welding → welding aimed at mass production - Cost reduction in manufacturing equipment ■BMS (Battery Management System) Monitors and controls the battery's voltage, temperature, and inter-cell balance. Contributes to extending lifespan by suppressing degradation factors.
