ANAS 4S–24S 40A–400A Heavy-Duty Smart BMS with CAN / RS485 / Bluetooth for LFP, NCM & LTO Battery Packs

4-Layer Heavy Copper & 4th-Gen MOS

Manufactured in China with 4-layer thick-copper PCBs engineered for heavy continuous current transmission. Upgraded with 4th-generation low-RDS(on) power MOSFETs to deliver superior overcurrent endurance, lower heat generation, and ultra-compact dimensional packaging.

Structural Resin Potting (IPX7 Sealed)

The entire electronic control assembly is encapsulated using precision industrial potting technology. Delivers complete moisture resistance, anti-oxidation, splash-proof sealing, and mechanical shock absorption against violent vehicle road vibrations.

High-Precision AFE & Deep Sleep Mode

Equipped with high-precision Analog Front-End (AFE) sampling for millivolt-level cell voltage detection. Integrated Bluetooth and a new micro-ampere Deep Sleep function eliminate self-discharge during long-term commercial warehouse storage or international sea transit.

Multi-Channel Communication Buses

• Dual UART Ports: Dedicated channels for concurrent host PC debugging and auxiliary module interfacing.
• Industrial CAN Bus: High-speed CANopen / J1939 protocols matching commercial EV motor controllers.
• Isolated RS485 / RS232: Industrial-grade differential bus for reliable telemetry in high-EMI environments.
• Single-Wire: Simplified, cost-effective digital dashboard and instrument cluster telemetry.

Plug-and-Play Hardware Peripherals

• LCD Display Integration: Direct serial connection for real-time voltage, SOC, and fault code dashboards.
• 4G Cloud IoT Telemetry: Seamless plug-in pairing with ANAS-IOT modules for GPS positioning and remote lock.
• PTC Heating Module: Automated low-temperature pre-heating control for sub-zero winter charging.
• WiFi & Alarm Buzzer: Real-time wireless configuration and audible early warning for over-temp or short circuit.

Q: How does the universal 4S to 24S compatibility work across different battery chemistries?

A: Our smart BMS hardware architecture utilizes an adaptive Analog Front-End (AFE) controller capable of flexible series grouping (4~8S, 7~17S, 7~24S for LFP; 4~7S, 7~17S, 7~20S for NCM; and 6~24S for LTO). Chemistry profiles, overvoltage thresholds, and balancing logic can be seamlessly configured via Bluetooth App or host PC software.

Q: Can ANAS customize CAN bus DBC files and communication protocols for our vehicle controller?

A: Yes. We provide complete OEM/ODM protocol engineering support. Our embedded software division can customize CANopen, J1939, or proprietary customer-specified communication baud rates, message IDs, and telemetry data structures to interface directly with your motor controller and digital dashboard.

Q: What is the sample availability and wholesale production lead time for BMS boards?

A: We supply prototype sample units for bench evaluation and vehicle controller integration testing. Wholesale production orders require 15 to 25 working days from our Huzhou base, with technical support backed by our European Service Center in Milan, Italy.
