Even conservatively estimating 80% efficiency and 80% cruise speed, and estimating 25% peak power during cruise, that's:

    83.1 km = (112kWh x 80% x 25 mph x 1.6 km/mile x 80%) / (138 kW x 25%)

which is an armchair number plenty close to the claimed 100 kilometers. And if it only has to go 2 km eight times a day, it's going to use less than a third of its capacity.
