+## 🔋 What is Qi Wireless Charging?
16
+**Qi** (pronounced *"chee"*) is a **wireless power transfer standard** developed by the **Wireless Power Consortium (WPC)**.
17
+It allows devices such as smartphones, earbuds, and wearables to charge **without cables**, using **inductive power transfer**.
18
+
19
+---
20
+
21
+## ⚙️ How It Works
22
+Qi charging uses **electromagnetic induction** between two coils:
23
+- **Transmitter coil (Tx)** – in the charging pad/base.
24
+- **Receiver coil (Rx)** – inside the device (e.g., phone or earbuds).
25
+
26
+### Process:
27
+1. The charger creates an **alternating magnetic field**.
28
+2. The receiver coil in the device converts it into **electrical energy**.
29
+3. This energy is used to **charge the battery**.
30
+
31
+---
32
+
33
+## ⚡ Technical Details
34
+
35
+| Parameter | Typical Value | Notes |
36
+| ------------------ | ------------- | --------------------------------- |
37
+| **Frequency** | 110–205 kHz | For inductive power transfer |
38
+| **Voltage Output** | 5V / 9V / 12V | Depending on power profile |
39
+| **Power Levels** | 5W, 10W, 15W | Standard Qi power levels |
40
+| **Efficiency** | ~70–85% | Depends on alignment and distance |
41
+| **Distance** | ≤ 5 mm | Coil-to-coil gap must be small |
42
+
43
+---
44
+
45
+## 🧩 Qi Power Profiles
46
+| Profile | Power | Usage |
47
+| --------------------------------------- | ---------- | ------------------------------------- |
48
+| **Baseline Power Profile (BPP)** | Up to 5W | Universal compatibility |
49
+| **Extended Power Profile (EPP)** | Up to 15W | Fast wireless charging |
50
+| **Future Qi2 (Magnetic Power Profile)** | Up to 15W+ | Magnetic alignment, higher efficiency |
51
+
52
+---
53
+
54
+## 🧲 Qi2 Standard (2023–2025)
55
+The **Qi2** update introduces:
56
+- **Magnetic Power Profile (MPP)** — based on Apple’s **MagSafe** design.
57
+- **Automatic alignment** via magnets for higher efficiency.
58
+- **15W fast charging** standardized for all brands.
59
+- **Backward compatibility** with older Qi devices.
60
+
61
+---
62
+
63
+## ✅ Advantages
64
+- No physical cable wear or connector damage.
65
+- Water/dust sealing possible (no exposed port).
66
+- Universal compatibility across many brands.
67
+
68
+---
69
+
70
+## ⚠️ Limitations
71
+- Slower than wired fast charging.
72
+- Requires precise coil alignment.
73
+- Generates more heat.
74
+- Charging distance is short (<5 mm).
75
+
76
+---
77
+
78
+## 📱 Common Qi-Compatible Devices
79
+- Most modern **Android** phones (Samsung, Xiaomi, Huawei, etc.)
80
+- **Apple iPhones** (iPhone 8 and later)
81
+- **Wireless earbuds** with Qi charging cases
82
+- **Smartwatches** (select models)
83
+
84
+---
85
+
86
+## 🧠 Tip
87
+For best performance:
88
+- Use **Qi-certified** chargers.
89
+- Avoid **metal cases** or **thick covers** (>3 mm).
90
+- Center the device properly on the pad.
91
+- Keep the pad **cool and dust-free**.
92
+

20
+
21
+
22
+## Method 2.
23
+
24
+If building your own charger or pack, include a BMS, and use a charger with current limit and CV/CC behavior.
25
+
26
+如果你自己DIY电池组或充电系统，务必使用保护板（BMS），并选择支持恒流恒压输出的充电器。

5
+### 1. The USB-C "Boost" Solution: IP2326
6
+This is arguably the best modern chip for 2S DIY projects. It takes a standard **5V USB input** and "boosts" it to 8.4V.
7
+
8
+* **Input:** 4.5V – 5.5V (USB Standard).
9
+* **Charging Current:** Up to 15W (~1.5A–2A).
10
+* **Key Advantage:** It features **integrated cell balancing**. Most simple chargers ignore the middle tap, but the IP2326 monitors both cells to ensure they stay equal.
11
+* **Best For:** Your Rover V2 or any device you want to charge with a phone charger.
12
+
13
+
14
+
15
+---
16
+
17
+### 2. The High-Voltage "Buck" Solution: TP5100
18
+A very popular, robust switching buck (step-down) charger. It is more efficient than the older TP4056 and handles much higher power.
19
+
20
+* **Input:** 5V – 18V (Note: You need at least **9V–12V** input to charge a 2S pack).
21
+* **Charging Current:** Programmable up to **2A**.
22
+* **Key Advantage:** Very simple peripheral circuit (few external components). You can switch between 1S and 2S mode by shorting the "SET" pins.
23
+* **Best For:** Your scooter project if you plan on using a dedicated 12V power brick.
24
+
25
+
26
+
27
+---
28
+
29
+### 3. The Professional "Power Path" Solution: BQ24133
30
+A high-end synchronous switched-mode charger from Texas Instruments.
31
+
32
+* **Input:** 4.5V – 17V.
33
+* **Charging Current:** Up to **2.5A**.
34
+* **Key Advantage:** **Dynamic Power Management.** It can power your system (the Rover's motors/sensors) and charge the battery at the same time. If the motor draws too much current, it automatically reduces the charging current to prevent the power supply from crashing.
35
+* **Best For:** Professional-grade robotics where the system must stay "on" while plugged in.

54
+
55
+### Critical Design Tip: The "Balance" Requirement
56
+Since you are building a **scooter**, safety is paramount.
57
+* If you use the **TP5100** or **BQ24133**, they do *not* balance the cells. You **must** pair them with a 2S BMS (like the HY2120 mentioned earlier) that has a balancing function.
58
+* If you use the **IP2326**, it handles balancing internally, making the PCB design much safer for the batteries.

10

11
+QC 2.0: Uses the D+ and D- data lines of a USB cable to negotiate voltage by changing the DC voltage levels on those pins.
12
+
13
+USB PD: Uses a dedicated CC (Configuration Channel) line inside the USB-C cable to send high-speed digital data packets for negotiation.
14
+
15
+2. Physical Interface
16
+
17
+`QC 2.0` was designed for USB-A to Micro-USB cables.
18
+
19
+`USB PD` requires a USB-C to USB-C (or USB-C to Lightning) connection to utilize the CC pin.

38
+QC 2.0 / 3.0: Proprietary and Incompatible with PD.
39

-## 🔋 What is Qi Wireless Charging?
16
-**Qi** (pronounced *"chee"*) is a **wireless power transfer standard** developed by the **Wireless Power Consortium (WPC)**.
17
-It allows devices such as smartphones, earbuds, and wearables to charge **without cables**, using **inductive power transfer**.
18
-
19
----
20
-
21
-## ⚙️ How It Works
22
-Qi charging uses **electromagnetic induction** between two coils:
23
-- **Transmitter coil (Tx)** – in the charging pad/base.
24
-- **Receiver coil (Rx)** – inside the device (e.g., phone or earbuds).
25
-
26
-### Process:
27
-1. The charger creates an **alternating magnetic field**.
28
-2. The receiver coil in the device converts it into **electrical energy**.
29
-3. This energy is used to **charge the battery**.
30
-
31

33
-## ⚡ Technical Details
34
-
35
-| Parameter | Typical Value | Notes |
36
-| ------------------ | ------------- | --------------------------------- |
37
-| **Frequency** | 110–205 kHz | For inductive power transfer |
38
-| **Voltage Output** | 5V / 9V / 12V | Depending on power profile |
39
-| **Power Levels** | 5W, 10W, 15W | Standard Qi power levels |
40
-| **Efficiency** | ~70–85% | Depends on alignment and distance |
41
-| **Distance** | ≤ 5 mm | Coil-to-coil gap must be small |
42
-
43
----
44
-
45
-## 🧩 Qi Power Profiles
46
-| Profile | Power | Usage |
47
-| --------------------------------------- | ---------- | ------------------------------------- |
48
-| **Baseline Power Profile (BPP)** | Up to 5W | Universal compatibility |
49
-| **Extended Power Profile (EPP)** | Up to 15W | Fast wireless charging |
50
-| **Future Qi2 (Magnetic Power Profile)** | Up to 15W+ | Magnetic alignment, higher efficiency |
51
-
52
----
53
-
54
-## 🧲 Qi2 Standard (2023–2025)
55
-The **Qi2** update introduces:
56
-- **Magnetic Power Profile (MPP)** — based on Apple’s **MagSafe** design.
57
-- **Automatic alignment** via magnets for higher efficiency.
58
-- **15W fast charging** standardized for all brands.
59
-- **Backward compatibility** with older Qi devices.
60
-
61
----
62
-
63
-## ✅ Advantages
64
-- No physical cable wear or connector damage.
65
-- Water/dust sealing possible (no exposed port).
66
-- Universal compatibility across many brands.
67
-
68
----
69
-
70
-## ⚠️ Limitations
71
-- Slower than wired fast charging.
72
-- Requires precise coil alignment.
73
-- Generates more heat.
74
-- Charging distance is short (<5 mm).
75
-
76
----
77
-
78
-## 📱 Common Qi-Compatible Devices
79
-- Most modern **Android** phones (Samsung, Xiaomi, Huawei, etc.)
80
-- **Apple iPhones** (iPhone 8 and later)
81
-- **Wireless earbuds** with Qi charging cases
82
-- **Smartwatches** (select models)
83
-
84
----
85
-
86
-## 🧠 Tip
87
-For best performance:
88
-- Use **Qi-certified** chargers.
89
-- Avoid **metal cases** or **thick covers** (>3 mm).
90
-- Center the device properly on the pad.
91
-- Keep the pad **cool and dust-free**.
