60 kWh is the energy needed to lift a load of 30 metric tonnes up 720 meter (about 2400 foot).
That would in itself be enough to clear most hills, and we're talking about a hybrid solution, so if the engine and motor divide the load they'd go twice the height before the engine is left on its own. It isn't magic, but it is substantial.
The pack should be able to deliver 300 kW to the wheels, doubling the power available for acceleration and climbing. That would save truck drivers a lot of time.
A 10 kWh pack in a semi would only work well as a start-stop system. It would run out in 2 miles of city traffic, and it wouldn't be able to provide enough power to make much difference in acceleration.
