Nexisense ZE630-H2 Hydrogen Detection Module: Professional-grade Monitoring Front-end for Energy Storage and Hydrogen Energy Fields

In lithium-ion battery energy storage systems (BESS), new energy vehicle power battery packs, and industrial hydrogen applications, hydrogen, as an early characteristic gas of thermal runaway, has become a core requirement for safety compliance to monitor its trace release. Traditional electrochemical sensors often face issues such as electrolyte leakage, signal drift, and complex analog conditioning, leading to high integration difficulty and increased maintenance costs.

The Nexisense ZE630-H2 module is based on an optimized fuel cell-type electrochemical principle. Through a highly sealed structure and integrated digital processing circuit, it provides stable, plug-and-play hydrogen sensing capabilities. It has been validated in multiple GW-level energy storage projects and vehicle BMS solutions, becoming the component of choice for system integrators to build reliable hydrogen monitoring networks.

Typical Application Scenarios and Project Integration Value

With its low power consumption, wide temperature range, and digital output characteristics, the ZE630-H2 adapts to various harsh scenarios, achieving hydrogen risk sensing from the local to the station level.

· Electrochemical Energy Storage Stations (BESS): In containerized or station-level BESS, the early stage of thermal runaway is often accompanied by trace hydrogen release (<100 ppm). The ZE630-H2 can be distributed within battery clusters, between modules, and along cabin ventilation paths, connecting to the BMS or local controller via a UART interface to realize multi-point concentration monitoring and trend analysis. In actual projects, when the hydrogen warning threshold is set to 20-50 ppm, this module can trigger a first-level alarm 10-20 minutes in advance, linking with ventilation/fire extinguishing systems, significantly enhancing system safety and national standard compliance.

Typical distributed monitoring example within an energy storage cabin:

· New Energy Vehicle Battery Management System (BMS): Automotive lithium battery packs are prone to producing hydrogen in scenarios such as overcharging, short circuits, or collisions. The ZE630-H2's miniaturized packaging and low-power design facilitate embedding inside battery packs or near high-voltage boxes, interfacing directly with the BMS MCU via PWM/UART output, and supporting CAN bus bridging. Project verification shows that in simulated thermal runaway tests, the module response time is<30 s, with a linear output accuracy of ±5% FS, effectively supporting BMS hierarchical warning logic.

· Industrial Hydrogen and Fuel Cell Applications: Hydrogen fuel cell stations, hydrogen refueling stations, and electrolysis hydrogen production equipment require real-time monitoring of hydrogen leakage and accumulation risks. The ZE630-H2 supports multi-module networking (via external adapter boards) to connect to PLC/SCADA systems, achieving station-level centralized monitoring and remote data upload. It is suitable for outdoor environments with IP65 protection requirements.

In these scenarios, as the front-end sensing module, the ZE630-H2's standardized digital output and low-drift characteristics significantly reduce system integration complexity, enhancing overall availability and project delivery efficiency.

ZE630-H2 Module Selection Guide: Matching System Requirements

Selection should be based on the monitoring range, interface type, and environmental requirements. Core technical parameters reference:

Selection Recommendations:

· BESS/Energy Storage Projects: Prioritize the 0-1000 ppm range, emphasizing low power consumption and UART output.

· Automotive BMS Integration: Choose the miniaturized, low-voltage version supporting PWM rapid response.

· Industrial Hydrogen Stations/Refueling Stations: Use wide-range and high-protection models.

· Multi-point Networking Schemes: Evaluate RS485 expansion compatibility (requires external adapter).

System Integration Considerations and Best Practices

To ensure stable operation of the ZE630-H2 in actual projects, integration should focus on the following engineering points:

· Installation and Arrangement: Place the module in a low-lying area where hydrogen easily accumulates, avoiding direct exposure to condensation or oil mist; a protective cover is recommended.

· Signal Interface: The default UART output baud rate is 9600 bps, which supports customization; PWM is used for simple threshold alarms and requires an external pull-up resistor.

· Power Design: Adopt stable 3.3V/5V LDO power supply to avoid ripple >50 mV affecting ADC accuracy.

· Data Processing: The module has built-in temperature compensation and non-linear correction. It is recommended that the MCU collects concentration values every 5-10 s and performs sliding average filtering to suppress noise.

· EMC Compatibility: Areas near high-power PCS/motors require shielded cables and filter capacitors, compliant with IEC 61000-4 series tests.

· Maintenance Strategy: Pre-calibrated at the factory; perform bump test every 12 months in the field; supports self-diagnosis (broken wire/out-of-range alarm).

Typical integrated circuit reference: Module UART TX/RX connects directly to MCU, PWM output connects to interrupt pin to trigger alarm.
