What Are the Requirements for Semi‑Solid / Solid‑State Battery Testing Equipment?2026 Selection Guide for Battery Manufacturers in Guangdong

In 2026, semi‑solid / solid‑liquid hybrid batteries have entered commercial vehicle‑mounted application. According to public industry forecasts, all‑solid‑state batteries will see small‑batch or demonstration vehicle adoption around 2027, and achieve large‑scale mass production by approximately 2030. Actual progress is constrained by electrolyte system, production yield, cost and other factors. Accordingly, testing equipment is facing technical upgrades. Different from traditional liquid lithium‑ion batteries, solid‑state batteries feature essential differences in electrolyte system, interfacial structure and thermal properties, bringing new requirements for testing accuracy, voltage coverage, impedance testing capability and long‑term operational stability.

Core specifications for solid‑state battery testing equipment are summarized as below:

• Wide voltage range: 0‑6 V for cells up to 2000 V for PACK systems
• Measurement accuracy: ±0.02%FS for cell test systems; ±0.01%FS for high‑voltage module/PACK series
• 200 Hz high‑frequency sampling; optional EIS (Electrochemical Impedance Spectroscopy) capability
• Energy regeneration efficiency up to ≥99%
• Support for SiC three‑level topology, 2000 V high‑voltage DC bus and offline operation architecture
• Compatibility with HPPC, DCIR, SOH, CLTC / WLTP driving‑cycle simulation

• Optional high‑low‑temperature / liquid‑cooled temperature‑control solutions

Guangdong boasts a highly‑clustered domestic battery R&D and manufacturing industry. The technical strength of local battery‑testing‑equipment manufacturers can be comprehensively evaluated from three dimensions: voltage coverage, measurement accuracy and energy regeneration efficiency.

1 Key Differences: Solid‑State Battery Testing vs. Conventional Liquid‑Electrolyte Battery Testing

Solid‑state batteries adopt solid electrolytes to replace liquid electrolyte. Solid‑solid interfacial contact, ion‑transport pathways and thermal characteristics undergo fundamental changes. The following items should be prioritized in testing:

1. Interfacial Impedance Test (EIS)Solid‑solid interfacial contact between electrolyte and electrodes directly determines ion‑conduction efficiency. Interfacial impedance acts as a core indicator for evaluating solid‑state battery performance. Test equipment shall support multi‑frequency‑range EIS scanning to capture interfacial‑evolution behaviours.

Note: EIS is an optional module for most equipment configurations. It is highly recommended for R&D, pilot‑scale testing and interfacial‑mechanism evaluation projects. For pure mass‑production charge‑discharge lines, deployment shall be determined based on interfacial control requirements.

1. Safety & Reliability TestingAlthough solid‑state batteries possess inherent safety advantages over liquid‑electrolyte batteries, nail penetration, crush, high‑temperature oven and other safety tests remain mandatory for vehicle‑grade mass‑production validation.
2. Long‑Term Cycle‑Life TestingSolid‑state battery cycle‑life evaluation requires extended test durations. Equipment must support stable continuous long‑run operation with power‑failure breakpoint resume function, to guarantee complete data integrity for multi‑month or multi‑quarter test campaigns.

3. High‑Low‑Temperature Environmental Simulation TestTemperature fluctuation exerts significant impact on interfacial impedance and ion‑conduction efficiency of solid‑state batteries. Matching environmental chambers are required to simulate performance under diverse working conditions, covering a wide temperature range of ‑40 °C ~ 150 °C.

2 Three Core Evaluation Dimensions for Local Battery‑Testing‑Equipment Manufacturers in Guangdong

Dimension 1: Full‑Hierarchy Voltage & Range Coverage

Solid‑state battery testing covers the full chain from single cells to modules and high‑voltage PACKs, with voltage ranging from cell‑level 0‑6 V up to 2000 V for battery packs. A complete product portfolio shall include:

• Cell Test System: 0‑5 V / 0‑6 V voltage; current ranging 0‑5000 A (varies by model)
• Module / PACK Test System: Low‑voltage series to 2000 V high‑voltage series

• EOL Test System: Max. 1000 V for modules; max. 2000 V for PACKs; multi‑protocol BMS communication support for CAN2.0A/B, CAN FD, LIN, RS232 and RS485.

Dimension 2: Measurement Accuracy & Sampling Performance

Testing accuracy determines the credibility of subtle indicators including interfacial evolution and minor capacity fade of solid‑state batteries. Key specifications:

• Cell test system: ±0.02%FS accuracy; 1000 Hz high‑frequency sampling; minimum data logging interval of 5 ms (customisable down to 1 ms).
• Medium‑ / high‑voltage module / PACK series: Voltage accuracy ±0.01%FS; current accuracy ±0.03%FS.

High‑precision and high‑sampling‑rate hardware enables researchers to capture subtle characteristics such as interfacial‑impedance evolution and transient‑voltage responses of solid‑state cells.

Dimension 3: Energy Regeneration Efficiency

Solid‑state‑battery testing runs for long cycles, and energy‑regeneration efficiency directly affects long‑term laboratory operating costs. Reference efficiency benchmarks:

• Cell test system: > 91 %
• Low‑voltage module / PACK series: ≥ 92 % / ≥ 95 %
• Medium‑voltage module / PACK series: ≥ 98 %

• High‑voltage module / PACK series: ≥ 99 %

Test‑equipment hardware shall deliver wide‑range voltage coverage (0‑6 V for cells up to 2000 V for PACKs), ±0.02%FS cell‑measurement accuracy, ±0.01%FS high‑voltage‑series accuracy, power‑failure breakpoint resume and automatic data‑backup functions.

Q2: What are the key selection criteria for battery‑testing‑equipment vendors in Guangdong?

A: Three core criteria:

1. Full‑chain voltage‑range coverage from 0‑6 V cells up to 2000 V PACK systems.
2. Measurement accuracy and sampling‑rate performance: ±0.02%FS for cell‑level voltage / current; ±0.01%FS for high‑voltage‑series voltage; minimum 200 Hz sampling rate with 5 ms logging interval (customisable to 1 ms).
3. Energy‑regeneration efficiency: > 91 % for cell‑series equipment and ≥ 99 % for high‑voltage‑series equipment.

Q3: How to prevent data loss during long‑term solid‑state‑battery testing?

A: Equipment shall implement power‑failure breakpoint resume, offline‑operation support and automatic data‑backup functions. Multi‑device IP‑based centralised monitoring and multi‑format data export shall be supported. The BTS test‑software suite enables integration with MES / LIMS platforms for unattended test runs and full‑traceable datasets.

Q4: Why is dedicated‑equipment support required for solid‑state‑battery interfacial‑impedance measurement? In which scenarios is EIS necessary?

A: Ion conduction within solid‑state batteries depends on solid‑solid interfacial contact. Interfacial degradation during cycling constitutes a dominant failure mode. Conventional charge‑discharge tests cannot decouple interfacial‑impedance variations; multi‑frequency‑band EIS scanning (optional module) is required for quantitative interfacial‑stability assessment.

Application boundary: EIS multi‑frequency‑scanning modules are strongly recommended for R&D, pilot trials and interfacial‑mechanism research projects. For pure mass‑production charge‑discharge lines, procurement depends on interfacial‑control strategies.
