  "textContent": "A fuel cell and battery power management system for a fuel cell-powered vehicle includes an electric traction motor, a traction battery in electrical communication with the electric traction motor, a fuel cell stack in electrical communication with the traction battery and the electric traction motor, and a vehicle control system. The vehicle control system is configured to operate the vehicle with at a first discharge power level and a first charging power level if fuel cell power is sufficient alone to navigate the uphill grade and to build up battery state of charge by charging the traction battery at a second charging power level when the vehicle is approaching an uphill grade if fuel cell power is not sufficient alone to navigate the uphill grade. The vehicle control system is further configured to initiate proactive depletion of the battery SOC to enable powertrain braking and to provide regenerative power.",
