Solid-State Battery All-in-One Testing System

Why Choose Solid-State Battery All-in-One Testing System?

For solid-state and small-cell research, thermal stability and time-synchronized electrical data determine whether a dataset is publishable. By unifying the chamber with an 80-channel cycler, the WHW-200L removes the thermal drift, wiring inconsistency and timestamp misalignment common in split setups; per-channel pressure sensing extends measurement into solid-electrolyte interfacial evolution. The self-developed controller and Ethernet host interface let engineers script temperature-linked step profiles for long, unattended cycling campaigns.

True all-in-one architecture 

Charge/discharge testing and thermal enclosure are integrated into one chassis, so temperature and electrochemical data are time-synchronized out of the box, eliminating separate cabinets, long wiring runs and alignment errors.

High-precision thermal control

Forced-air circulation with auto-tuned PID; no-load fluctuation ≤±0.5°C, heating 25→85°C in ≤30 min, cooling 25→0°C in ≤50 min (no-load, non-linear average).

80-channel parallel testing 

5 V / 100 mA per channel, five-layer tray layout (16 channels per layer), ideal for high-throughput small-cell screening.

Self-developed controller + Ethernet 

LED digital display with touch keys, standard Ethernet interface to the host PC, programmable step profiles, remote monitoring and traceable data.

Per-channel pressure sensing 

Every channel is equipped with a pressure transducer, capturing interfacial strain and contact-resistance evolution—critical for solid-state cell R&D.

Robust refrigeration & heating 

Hermetic reciprocating compressor, air-cooled, R134a refrigerant, nitrogen-purge brazing; SSR zero-cross pulse-width heating for stable long-duration runs.

Safe & ergonomic 

Leakage/over-current/fan-fault protection; anti-fog tempered glass door with LED lighting; five φ50 mm cable ports; four braked casters; four layers of insulating Bakelite trays (20 kg/layer evenly distributed).
