Development of High Power Energy Storage for the CIVIC Hybrid

Article of Honda R&D Technical Review Vol.14 No.2

Summary

An attempt was made to improve the power density of a conventional nickel metal-hydride battery for installation of a hybrid system in the limited space available in a heavier vehicle. The plates were extended by 12%, the negative collector tab was eliminated, and the number of welds joining plate and collector was increased. These measures reduced the internal resistance by 19%. As a result, the power density during regeneration improved by 27%, making it possible to deal with increased regeneration energy without increasing the cubic volume of energy storage installed.
