How to decode data response from Ioniq EV (28kWh) #42

I try to read out OBD-2 data from Hyundai Ioniq Electro (Version 28kWh), using a Raspberry PI and a Bluetooth ELM327 interface. Connection and data transfer works fine.

For example: sending 2105<cr><lf> gives a response (<cr> is value 0x0d = 13):
7F2112<cr>7F2112<cr>7F2112<cr>02D<cr>0:6105FFFFFFFF<cr>7F2112<cr>1:00000000001616<cr>2:161616161621FA<cr>3:26480001501616<cr>4:03E82403E80FC0<cr>5:003A0000000000<cr>6:00000000000000<cr><cr>>

The value C0 in 4:03E82403E80FC0 seems to be the State of charge (SOC) display value:
C0 -> 192 -> 192/2 % = 96%

There are some tables for decoding available (see https://github.com/JejuSoul/OBD-PIDs-for-HKMC-EVs/tree/master/Ioniq%20EV%20-%2028kWh), but how to use these tables?

For example sending 2101<cr><lf> gives the response:

02C<cr>
0:6101FFFFF800<cr>
01E<cr>
0:6101000003FF<cr>
03D<cr>
0:6101FFFFFFFF<cr>
016<cr>
0:6101FFE00000<cr>
1:0002D402CD03F0<cr>
1:0838010A015C2F<cr>
7F2112<cr>
1:B4256026480000<cr>
1:0921921A061B03<cr>
2:000582003401BD<cr>
2:0000000A002702<cr>
2:000F4816161616<cr>
2:00000000276234<cr>
3:04B84100000000<cr>
3:5B04692F180018<cr>
3:01200000000000<cr>
3:1616160016CB3F<cr>
4:00220000600000<cr>
4:00D0FF00000000<cr>
4:CB0100007A0002<cr>
5:000001F3026A02<cr>
5:5D4000025D4600<cr>
6:D2000000000000<cr>
6:00DECA0000D8E6<cr>
7:008A2FEB090002<cr>
8:0000000003E800<cr>
<cr>
>

Please note, that the line feed was added behind every carriage return (<cr>) for better readability and is not part of the original data response.

How can I decode temperature, currents, ... from these data?
