EMONI

SUMMARY OF THE RESULTS ELECTRIC EFFICIENCY HEAT GENERATION DURING OPERATION • GOOD WELDABILITY WITH CELL ARRESTERS IN THE RESISTANCE-SPOT WELDING PROCESS • HIGHER ELECTRIC EFFICIENCY • GOOD FORMABILITY • GOOD HEAT DISSIPATION Regarding the comparative material, negative effects during the sheet treatment as well as the performance could not be identified on system-level. The system tests showed a similar electrical system be- haviour for all contacting materials. The measuring errors included both tested materials showed a slightly better efficiency as compared with the diffusion-annealed The examination of the heat generation in the module suggests a slightly improved heat dissipation with the copper-plated EMONI-CU premium material as compared with the diffu-nickel and EMONI. EMONI itself and the comparitive material are on an equi- valent level. On the contrary, slight advantages of EMONI could be observed with respect to the electric efficiency and the heat dissipation. comparative material. The charging and discharging ca- pacities are within the same range, showing slight advan- tages of the EMONI and EMONI-CU. 6 33,6°C DIFFU-NICKEL EMONI EMONI-CU 30,3°C 31,9 13,9 34,9 19,0 Diffu-Nickel Start-of-charge voltage End-of-charge voltage End-of-charge current Charging capacity Discharging capacity Efficiency
