1. Product Overview

The JLS-B-Z24S-071-V5 is a high-reliability Battery Management System (BMS) engineered by Shenzhen Jinlisheng Electronics for next-generation sodium-ion battery packs. While natively designed for 23-series (23S) configurations, the firmware architecture supports flexible adaptation for 6S to 16S applications via parameter configuration, making it an ideal solution for energy storage systems (ESS), low-speed EVs, and industrial backup power.

Built on the Sinowealth SH3676xx platform, this BMS ensures precise cell voltage monitoring and robust safety management, fully compliant with RoHS standards.

2. Key Features & Advantages

Features Category Technical Details Technical Details Business Value

Sodium-Ion Optimization Tailored voltage thresholds for Na-ion chemistry (OVP: 3.95V). Maximizes the cycle life and safety advantages of sodium batteries.

Flexible Compatibility Native 23S design with software support for 6S-16S. Reduces SKU complexity for distributors; one board fits multiple projects.

Robust Power Stage Uses Depp/Longxia MOSFETs (DP043N14BGN/LR036N12S2). Low Rds(on) ≤ 30mΩ minimizes heat generation during 50A continuous discharge.

Precision Protection Multi-level OCP (150A/300A) & μs-level short circuit protection. Prevents thermal runaway and protects downstream equipment.

Communication Ready Supports UART/RS485 (via reserved ports). Enables integration with IoT monitoring systems and inverters.

5. Hardware & BOM

To ensure supply chain stability, we use industrial-grade components:

• Protection IC: Sinowealth SH3676016B / SH3676010B

• MOSFETs: Depp (DP043N14BGN) / Longxia (LR036N12S2)

• Sense Resistors: 0.003R x 6 (Foshan Haoyun / TA-I)

Quality Note: To ensure optimal performance and supply continuity, component brands may be substituted between batches (e.g., MOSFETs) provided that electrical specifications meet or exceed the original design.
