With the countdown to the implementation of the “strictest-ever” new national standard for mobile power safety (GB 40165–2026), a wave of compliance and technology upgrades is sweeping across the entire industry.

The new standard imposes unprecedented requirements on protection functions, intelligent management, battery safety, and single-fault protection for mobile power products. These are not only the “lifeline” of product safety but also the “entry ticket” for brands to seize future market opportunities.

As a leading supplier of power management ICs and solutions, NuVolta Semiconductor has responded swiftly. Leveraging its deep expertise in both wireless and wired charging technologies, NuVolta has launched a complete mobile power solution portfolio that covers single‑cell and dual‑cell battery configurations and fully meets the core requirements of the new national standard.

2.2 Wired Communication Mode  
Through a USB cable / PD port or by manual trigger within the App, users can read complete detailed data logs and historical records.  
Demo solution: NU17113 + NU6801 + 2‑stage lithium protection + USB MCU + mobile App  

2.3 NFC  
Tap‑to‑read – without installing an App or connecting Bluetooth, the mobile phone can read core capacity and safety information, simple and efficient, supporting security inspections. NuVolta solutions also support NFC.

2.4 TFT Screen Display  
NuVolta solutions reserve screen interfaces to flexibly support customer TFT display requirements.

NuVolta does not offer a one‑size‑fits‑all interaction solution; instead, it provides a complete “toolbox” covering “basic compliance, wireless smart, and wired professional” options.

Key Features 
- Compliant with new national standard, supporting smart monitoring  
- External two‑stage lithium protection with passive balancing, protecting against single‑point failures  
- Built‑in high‑precision current sensing – battery current sampling accuracy < ±3% at >1A; especially critical for low‑temperature charging to prevent lithium plating  
- High‑precision voltage sensing – voltage accuracy ±1%  
- Built‑in high‑performance battery monitoring and gauge – outputs SOC, SOE, SOH information  
- External interactive MCU – flexible and configurable, supporting BLE, USB, TFT screen, and more  
- Built‑in high‑accuracy RTC (±1.5%) with calendar function  
- 128KB large Flash for data logging  
- Supports UL2056, CFCC, CE, 3C, etc.

**Advantages**  
- High integration: large Flash / high‑precision current and voltage sensing  
- Cost‑effective: no separate BMS needed – relies on powerful main controller plus two external lithium protection ICs to achieve new‑standard and UL2056 compliance  
- Enhanced safety: in addition to single‑fault requirements, NU6801/NU6802 integrate OCP, OTP, OVP, etc.

Meeting the New‑Standard Challenge – How NuVolta Solutions Deliver

PART 3

Dual Protection, Rock‑Solid Safety 
01  
The new standard and UL2056 both emphasise two‑stage independent protection and high‑precision fault detection.  
NuVolta solution: Uses two external, independent, high‑reliability lithium protection ICs, working with internal protection of the main controller to form a dual‑redundant system, strictly meeting the “protection under single‑fault condition” requirement.  
High‑precision current sense (CS): Built‑in high‑precision current‑sense amplifier enables milliampere‑level monitoring of charge/discharge currents, ensuring fast and accurate overcurrent and short‑circuit protection, meeting or exceeding the new standard’s current‑sensing accuracy requirements (e.g., <1A with ±50mA tolerance).

Intelligent Management, Full Visibility  
02  
The new standard requires mobile power to have smart monitoring and recording capabilities.  
NuVolta solution: NU6801/NU6802/NU6805 are high‑performance battery monitors and gauges, integrating high‑precision ADCs to achieve:  
- Voltage/temperature sensing: accuracy far exceeding the standard’s ±1% requirement, with independent monitoring per cell.  
- Full battery lifecycle management: accurately calculates and reports SOC (state of charge), SOE (state of energy), SOH (state of health), and automatically executes the required annual/cycle voltage‑degradation strategy to slow battery aging.  
- “Black box” function: built‑in high‑accuracy RTC (±1.5%) and 128KB Flash can log abnormal data (over‑charge, over‑discharge, temperature) every hour, with storage covering the product’s recommended safe service life.  
- Smart charge inhibition: supports undervoltage (Bat < 1.5V) and overvoltage lock‑out, removing the old “activation” logic for improved safety.

Battery Safety, Proactive Prevention
03  
The solution provides a solid foundation for passing stringent battery tests (over‑charge, crush, nail penetration, aging‑induced lithium plating, etc.). The external lithium protection and main‑controller built‑in protection work together – from cell level to system level – to maximise the avoidance of thermal runaway risks.

Single‑Fault, Confident Response 
04  
NuVolta solutions are designed from the outset with consideration of single‑point component failure risks. The two‑stage independent protection architecture ensures that even if one stage fails, the other remains effective, greatly enhancing system safety redundancy.
