Battery current sensor from HEYI Electric – Providing Safer Protection for Clean Energy

Why clean energy systems cannot do without leakage detection

Carbon neutrality is the common goal of the earth. In an era when clean energy is becoming increasingly popular – from electric vehicle charging stations to photovoltaic power generation systems and energy storage systems (ESS) – safety and efficiency are equally important.

These systems involve both alternating current (AC) and direct current (DC), and traditional AC leakage protectors cannot detect DC residual current, which can easily lead to detection blind spots and safety hazards.

HYCA series current sensors (RDC modules) can detect AC/DC leakage simultaneously, complying with IEC 62752 and IEC 62955 (RDC-PD) international standards. They are essential safety protection components in the clean energy field.

Core features of HYCA series battery current sensor

High-precision intelligent detection

Adopting AC/DC dual-sensitivity technology, it monitors leakage current in real time with a response speed as fast as 8.5ms.

Self-Test function

Before the system starts, it automatically simulates leakage current (typically 6.5mA DC) to verify whether the detection function is normal.

Ultra-low power consumption and long life

Power consumption ≤ 110mW, design life ≥ 20 years, supporting long-term stable operation.

PCB board installation, easy integration

Powered by a single +5V power supply, it can be directly embedded in the main control board to save space and wiring.

Wide temperature and weather resistance, suitable for global use

It can work reliably in an environment of -40℃~+85℃ and is suitable for climatic conditions around the world.

Typical application scenarios in the clean energy field

Electric vehicle charging station (AC/DC)

In EV charging systems, the HYCA battery current sensor module can simultaneously detect AC and DC leakage to prevent electric shock and equipment damage, meeting the requirements of the European IEC 62955 safety standard.

Photovoltaic inverter

In photovoltaic systems, leakage can be caused by humidity or insulation aging. HYCA modules detect leakage in advance to avoid fire risks and ensure safe power generation.

Energy Storage System (ESS)

High-voltage DC batteries are prone to tiny leakage currents. The HYCA module can accurately detect these leakages and ensure the long-term safety and stable operation of the energy storage system.

Electric two-wheelers and micro-mobility devices

The module is compact and has low power consumption, making it very suitable for electric bicycles, shared electric vehicle charging stations and portable energy storage and charging equipment.

Comparison of HYCA-10-PD and HYCA-16-PD

model	Current range	Core Features	Typical Applications
HYCA-10-PD	32A–40A	High sensitivity, standard RDC-PD module	Home and portable charging stations and converters
HYCA-16-PD	32A	Higher stability and self-checking optimization design	Public charging stations, photovoltaic and energy storage systems

Both products support fast tripping (8.5–100ms) and high and low-level output signals to meet the safety requirements of AC/DC hybrid systems.

Guardian of system safe operation

The HYCA module not only “detects problems” but also “prevents them.”
Each time it starts, the module performs a self-check to ensure the circuit is functioning properly. If it detects excessive residual current during operation, it immediately outputs a trip signal, quickly powering off the system and preventing accidents.

This means:

Users are more assured

The system is more secure
and enterprise maintenance is easier

Why engineers and system integrators trust HYCA battery current sensor

Plug and play design, quickly integrated into the motherboard

Comply with international IEC standards and are applicable to the global market

Support AC/DC hybrid system monitoring

Suitable for OEMs, EVSE manufacturers, and photovoltaic/energy storage solution providers

Build a safe green energy ecosystem together

Under the global trend of “carbon neutrality” and “electrification”, electrical safety is the foundation of sustainable development of clean energy.
The HYCA series current sensors provide intelligent, safe, and reliable underlying protection for the clean energy industry.

“Intelligent detection, safeguarding green energy security – this is HYCA’s mission.”
