1. はじめに
This manual provides detailed instructions for the installation, operation, and maintenance of the JKBMS 2A Active Balancer, Model JK-DZ11-B2A24S. This device is designed to manage and equalize voltage across individual cells in lithium battery packs (LiFePO4, Li-ion, LTO) ranging from 2S to 24S, ensuring optimal performance and extended battery lifespan.
The active balancer features a 2A balancing current, built-in Bluetooth for real-time monitoring via a mobile application, and RS485 communication. It supports a wide input voltage range of 20V-100V and offers precise voltage detection with an accuracy of ±3mV.
2. 安全情報
- Always disconnect the battery pack before performing any wiring or maintenance.
- Ensure correct polarity when connecting the balancer to the battery cells. Incorrect connections can cause damage to the device and battery.
- Do not short-circuit the balancer terminals.
- Operate the device within its specified voltageと現在の制限。
- Keep the device away from moisture, extreme temperatures, and flammable materials.
- Installation should be performed by individuals familiar with battery systems and electrical safety procedures.

4.製品オーバーview
The JKBMS Active Balancer is a compact unit designed for efficient cell equalization. Below is an image illustrating the device and its main connection points.
Figure 1: JKBMS 2A Active Balancer (Model JK-DZ11-B2A24S). The image shows the top view of the black rectangular unit with labels for balance current, model, sampling accuracy, number of battery strings, and supply voltage. Connection ports for B+, B-, TEMP, RS485/CAN, and balance wires (B1-B24) are visible along one edge.
主要な構成要素と指標:
- Balance Wire Ports: Connects to individual battery cells (B1 to B24).
- TEMP Port: For connecting the external temperature sensor.
- RS485/CAN Port: For communication with external devices or systems.
- Bluetoothモジュール： Integrated for wireless monitoring via mobile app.
- ステータスLED： Indicates operational status (e.g., balancing, error).
5. セットアップとインストール
Follow these steps carefully to install the JKBMS Active Balancer:
- バッテリーパックを準備します。 Ensure your battery pack is within the 2S-24S configuration and the total voltage is between 20V-100V. Individual cell voltages should be within safe operating limits.
- バランスワイヤを接続します。
- Connect the provided balance wire harness to the corresponding balance ports on the balancer unit.
- Carefully connect each wire from the harness to its respective cell tap on your battery pack, starting from B- (negative terminal of the first cell) up to B+ (positive terminal of the last cell). Ensure the order is correct (B1, B2, ..., B24). Incorrect wiring can damage the balancer or battery.
- 温度センサーを接続します: Plug the temperature sensor into the TEMP port on the balancer. Position the sensor appropriately to monitor battery temperature.
- Connect RS485/CAN (Optional): If using RS485 or CAN communication, connect the appropriate cables to the RS485/CAN port. Refer to the specific communication protocol documentation for detailed wiring.
- 電源オン: Once all connections are secure and verified, connect the main positive and negative terminals of the balancer to the battery pack's main terminals. The balancer will power on automatically.
Important: Double-check all wiring before applying power to prevent damage.
6. 操作手順
The JKBMS Active Balancer can be monitored and configured via its built-in Bluetooth module and a dedicated mobile application.
6.1 Mobile Application (JK App)
- アプリをダウンロード: 検索する "JK BMS" or "JKBMS" in your device's app store (available for iOS and Android).
- Bluetooth経由で接続：
- スマートフォンでBluetoothを有効にします。
- Open the JK App. The app should automatically detect nearby JKBMS devices.
- Select your balancer from the list to establish a connection.
- 監視： Once connected, the app will display real-time data, including:
- 個々の細胞体積tages
- Total pack voltage
- Balancing status (which cells are balancing)
- バッテリー温度
- Other relevant parameters.
- パラメータ調整: The app allows for configuration of certain balancing parameters. Refer to the in-app help or specific JKBMS documentation for details on adjustable settings.
6.2 ステータスLEDインジケータ
The device features a status LED to provide quick visual feedback:
- 緑色の点灯: Normal operation, cells are balanced or within acceptable deviation.
- 緑色に点滅: Active balancing in progress.
- 赤一色: Error condition. Check connections and app for details.
- 光なし: デバイスがオフになっているか、電源が入っていません。
7. メンテナンス
- クリーニング： Periodically clean the exterior of the balancer with a dry, soft cloth. Do not use liquid cleaners or solvents.
- 接続チェック: Regularly inspect all wiring connections for tightness and signs of corrosion or damage.
- ファームウェアの更新： Check the JKBMS official website or app for any available firmware updates. Follow the provided instructions carefully for any update procedures.
- ストレージ： If storing the balancer for an extended period, disconnect it from the battery pack and store it in a cool, dry place.
8。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| Balancer not powering on / No LED light | Incorrect main power connection; Battery voltage too low; Damaged unit. | Verify main positive and negative connections. Check battery pack voltage. Contact support if unit is damaged. |
| Cells not balancing | Balance wires incorrectly connected; Cell voltage difference too small; Balancer fault. | Check all balance wire connections for correct order and secure fit. Ensure cell voltage deviation exceeds the balancing threshold (check app settings). |
| Bluetooth経由で接続できません | Bluetooth disabled on phone; App not detecting device; Interference. | Ensure phone Bluetooth is on. Restart app and balancer. Try connecting in a different location to reduce interference. |
| Status LED is solid red | Error condition (e.g., over-voltage、under-voltage、温度）。 | Check the JK App for specific error codes or warnings. Address the underlying issue (e.g., battery voltage、温度）。 |
