“…This is the worst operation case that should not happen often because the SC self-discharge time constant is relatively long [26]. More advanced pre-charging strategies could be used in further studies, including short-circuit or progressive FC/SC connection [28], using a Voltage Stabilization System (VSS) [57], or a control system to regulate the connection of a pre-charging resistance before starting the vehicle [58].…”

Active configuration i.e., source coupling via a power converter, is the most common configuration for fuel cell/supercapacitor (FC/SC) vehicles. Passive connection of the FC with the SCs without any converters is an original and less expensive solution to distribute the power among the sources. This passive configuration does not require an energy management strategy. In fact, the power distribution only depends on the FC and SC impedance characteristics. Conventional methods to size the SC follow two criteria: storage capacity and maximum voltage. In this paper, a third criterion is added which is the FC operating current dynamics. This novel sizing methodology reduces the FC degradation and improves the global system efficiency. Experimental results provide validation to the proposed sizing approach. The SCs boost the FC to meet the requirements of the load with a guarantee of system stability reaching higher global performances and less stress to the FC.

“…In some cases, dump trucks can generate a positive energy balance of 200 kWh daily [21]. Other studies on mining dump truck's regenerative breaking can also be seen in [22][23][24]. Depending on the road slope, electric trucks can even provide hydropower, by transporting water down the mountains [25].…”
