Ah, I see! Would it look something like this? battery_level[j, d] <= battery_level[i, d] - e * time_drone[i, j] + M * (1 - D[i, j, d] + M*bin_charging(i, j, d)

Oh, I do have a binary variable that indicates whether the drone is traveling alongside the vehicle. for i in range(2 * num_orders + 2): for j in range(2 * num_orders + 2): model.addConst...

for d in range(drone): for i in range(1, num_orders + 1): model.addConstrs(battery_level[i+num_orders, d] >= battery_level[i, d] - e*time_drone[i, f] + charging_rate*time_vehicle[f, l] ...
