Abstract
This study experimentally investigates the energy flow characteristics of a fuel cell (FC) hybrid electric heavy-duty truck under user-defined driving cycles. The analysis comprehensively examines three critical aspects including energy consumption distribution patterns, efficiency metrics of key powertrain components, and thermal management system performance. The results show that the FC stack achieves 47.98% conversion efficiency but suffers 49.6% thermal losses through coolant systems with power fluctuations, resulting in only 38.99% of initial energy reaching the wheels after accounting for losses in power electronics, transmission and auxiliary systems. The power battery effectively balances loads but…
