💖 NAME 💖

power_supply_temp2resist_simple — bestie, this is the one that finds your battery's internal resistance percent from the temperature 🌡️✨

✨ SYNOPSIS ✨

int power_supply_temp2resist_simple (const struct
power_supply_resistance_temp_table *table , int table_len , int temp );

🎀 ARGUMENTS 🎀

• table — a pointer to the battery resistance temperature table, like literally the whole lookup vibe 💅
• table_len — the table length, bestie. how many entries we're working with 🫶
• temp — the current temperature, that's the moment we're checking 🌡️

🦋 DESCRIPTION 🦋

Ok so picture this: this helper function is what you call to look up the battery internal resistance percent based on the current temperature value, pulling it out of the resistance temperature table 👑 And here's the thing — the table must be ordered descending 🔥 no cap, that's a hard requirement, don't come at it with an ascending table 😭

Then the actual math goes like this, and it's genuinely iconic:

the actual battery internal resistance = the ideal battery internal resistance * percent / 100 🧮✨

🌸 RETURN 🌸

It gives you back the battery internal resistance percent. That's it. That's the whole gift 🎁💜
