STRUCT EC_RESPONSE_BATTERY_DYNAMIC_INFO(9)

💖 struct ec_response_battery_dynamic_info(9) — Kernel API Manual 💖

okay bestie, welcome to the <pink>Kernel API Manual</pink> ✨ — yes the title got truncated in the header to struct ec_r...dynamic_info(9) but we're talking about the full struct ec_response_battery_dynamic_info here, no cap. it's the battery dynamic info response, and it's lowkey one of the most relatable structs in the whole EC firmware universe because it's literally just the battery telling you how it's feeling rn 🥺🔋

---

🌸 NAME 🌸

struct ec_response_battery_dynamic_info — the Battery dynamic info response. that's it, that's the vibe 💅

---

✨ SYNOPSIS ✨

here's the whole thing, exactly as it lives in the source, no notes:

struct ec_response_battery_dynamic_info {
    int16_t actual_voltage;
    int16_t actual_current;
    int16_t remaining_capacity;
    int16_t full_capacity;
    int16_t flags;
    int16_t desired_voltage;
    int16_t desired_current;
 };

it's giving "seven int16_t fields and a dream" 🎀 every single one is int16_t, so do NOT go cramming your huge numbers in there, bestie, i'm warning you 🫶

🦋 Members 🦋

okay so let's meet the cast, one field at a time, like a little reality show lineup 👑

• actual_voltage — Battery voltage, measured in <cyan>mV</cyan>. this is the "what's actually happening right now" number, the main character of the voltage world 💖
• actual_current — Battery current in <cyan>mA</cyan> — and here's the important lil detail: negative = discharging 😭 so if you see a minus sign, the battery's giving, not receiving. the way that sign flips the whole meaning… iconic.
• remaining_capacity — Remaining capacity, in <cyan>mAh</cyan>. your "how much juice is left" girlie 🧃
• full_capacity — Capacity in <cyan>mAh</cyan>, and yes, the original is very clear on this: it might change occasionally 🙈 so don't you dare hardcode it and act surprised later.
• flags — Flags! see EC_BATT_FLAG_*. that's the whole description, go look at the constants, i believe in you 🫶✨
• desired_voltage — Charging voltage desired by battery, in <cyan>mV</cyan>. this is the battery manifesting its voltage goals ⭐
• desired_current — Charging current desired by battery, in <cyan>mA</cyan>. same energy, current edition 🔥

ngl the pattern here is actual vs desired — what's happening vs what the battery wishes were happening. it's giving vision board vs reality check 💀

✨ that's the whole page, bestie ✨ this one shipped from <purple>./include/linux/platform_data</purple> back in <lavender>October 2026</lavender>, so if you're reading it later than that, congratulations on your excellent archival instincts 🧚 go forth and read your battery's dynamic info responsibly 💅🔋🫶
