An energy management strategy to concurrently optimise fuel consumption & PEM fuel cell lifetime in a hybrid vehicle

摘要: Abstract The cost and reliability of fuel cells are major obstructions preventing cell hybrid electric vehicle (FCHEV) from entering the mainstream market. However, many degradation methods strongly affected by operating conditions therefore can be mitigated optimisation Energy Management Strategy (EMS). causes identified literature a model is produced in order to estimate effect EMS on degradation. This used produce an optimal strategy for low speed campus using Stochastic Dynamic Programming (SDP). SDP controller attempts minimise total running cell, inclusive both consumption degradation, each weighted their respective costs. new shown increase lifetime 14%, with only 3.5% consumption, largely avoiding transient loading stack.
