Complete Test Solution for New-Energy Vehicle Power Batteries

1. Company Strength Introduction

Changzhou Hopetech Electronic Technology Co., Ltd., founded in 2009, is a national-level high-tech enterprise. We specialize in the R&D and manufacturing of high-precision test & measurement instruments with full in-house software and hardware development capabilities. Hopetech participates in the formulation of national metrology standards and ranks among China’s leading domestic brands for battery internal resistance testers.

Targeting the new-energy vehicle power battery industry, Hopetech delivers an all-in-one electrical-performance and safety test solution covering the full production chain of cells, modules and PACKs. Our instruments support automatic production-line communication connection, are supplied with English-language operation manuals, and provide remote technical support for global vehicle manufacturers, battery producers and third-party laboratories

✅ HT3563/D High–precision Battery Resistance Tester | Cell Sorting Inspector

Role: Consistency gate-keeper for cell grouping procedures

Main Functions: Synchronously test internal resistance and voltage of cells and small modules with high precision; internal resistance accuracy: 0.5 %, voltage accuracy: 0.01 %; single measurement completed in as fast as 10 ms; supports upper-and lower-limit sorting alarm.

Pain Points Solved: Precisely screen cells with excessive deviation in internal resistance and voltage. Ensure consistency of cells inside one single module, and prevent premature battery-pack degradation and driving-range shrinkage caused by inconsistency among individual cells.

✅ HT3564/L/H High–Voltage Battery Internal Resistance Tester | High–Voltage Module Inspector

Role: Inspector for connection reliability of vehicle-mounted high-voltage modules / battery packs

Main Functions: Maximum test voltage up to 1500 V; internal resistance measuring range: 0.1 μΩ ~ 3 kΩ; supports multi-channel synchronous scanning.

Pain Points Solved: Compatible with 400 V / 800 V high-voltage vehicle platforms. Test total voltage and connection internal resistance of high-voltage modules and battery packs, detect hidden risks such as loose-torque bolts and poor copper-bar contact, and guarantee stable and reliable high-voltage loops.

✅ HT9830 Battery PACK EOL Comprehensive Test System | PACK Final–Inspection Officer

Role: Final full-item safety gate-keeper for battery-pack off-line testing

Main Functions: Modular and customizable design. Integrates complete test items including OCV open-circuit voltage, cell-level voltage acquisition, internal resistance, AC/DC hipot, insulation resistance, equipotential bonding and temperature measurement. Supports BMS communication parsing and adapts to automated production lines.

Pain Points Solved: Complete full-set electrical-performance and safety compliance inspection for off-line PACKs in one-stop manner. Eliminates frequent switching between multiple separate instruments, shortens production-line cycle time, and blocks battery packs with insulation or high-voltage hazards from entering vehicle assembly.

✅ HT3568 Battery Comprehensive Tester | Cell–Quality Diagnostic Physician

Role: Dedicated instrument for incoming-material inspection and after-sales failure analysis

Main Functions: One-stop rapid screening of open-circuit voltage, AC internal resistance, DC internal resistance and self-discharge; replaces multiple single-function test instruments.

Pain Points Solved: Applied for incoming sampling inspection of cells and traceability of failed after-sales batteries. Rapidly locate problems such as cell performance degradation and abnormal self-discharge, supporting quality review and R&D optimization.

Hopetech’s test instruments do not operate as standalone units. They form a collaborative full-lifecycle test workflow for power batteries: Cell Consistency Sorting → High–Voltage Module Internal–Resistance Test → Full Electrical–Performance & Safety Final Inspection for Off–line PACKs

Each device performs its own task and conducts multi-layer quality checks to intercept defective products in advance, ensuring factory-out quality of power batteries and high-voltage safety of complete vehicles.
