Nickel-Hydrogen Battery State of Charge During Low Rate Trickle Charging

摘要

Battery temperature increase, due to low rate trickle charging, has beendetermined experimentally, using a six cell battery module in a test setup simulating the anticipated AXAF-1 prelaunch environment. Test results indicate trickle charge rates less than or equal to the self discharge rate do not increase dissipation beyond that due to the self discharge. Significant trickle charge rates (approximately C/500) result in battery temperatures only a few degrees (F) higher than those observed during periods of open circuit stand.
