percentage_charged shows 100 but Powerwall is clearly not charged

Hello!

Great library. Thank you so much @tdorssers!

I'm starting to explore some ideas for my personal use though I did discover something rather odd. Using this simple call:

import teslapy
with teslapy.Tesla('me@me.io') as tesla:
    powerwall = tesla.battery_list()
    powerwall[0].get_battery_data
    print(powerwall[0]['percentage_charged'])

The API returns: 100.

However, looking at my app, the actual percentage is clearly not 100%.

Clearly this isn't a problem with the library though I'm really surprised to see such a dramatic difference. nowhere in get_battery_data() do I see a number that matches what I see in the app.

I wonder if I have to do the math myself as the API does return:

    "energy_left": 7958.789473684212,
    "total_pack_energy": 26923,

Any thoughts?

FWIW I wrote this:

    powerwall = tesla.battery_list()
    data = powerwall[0].get_battery_data
    energy_left = round(data()['energy_left'],2)
    total_pack_energy = data()['total_pack_energy']

    print(round(energy_left / total_pack_energy * 100,2))

Which results (52.1) in a true representation of what the Tesla application displays (52) . Weird that it's no just part of the API. Though if someone has a cleaner way to do this I'm all ears.
