Mobile lithium battery short circuit testing machine

Mobile lithium battery short circuit testing machine STANDARD FEATURES

I. Product Overview

This tester is specially designed for cell phone lithium batteries (lithium cobalt cobaltate / ternary material / polymer soft pack batteries), through the simulation of the battery internal short-circuit, external short-circuit and other extreme conditions, to comprehensively assess the safety performance of the battery. The equipment integrates high-precision control module, multi-dimensional monitoring system and intelligent protection mechanism to meet the needs of full-cycle testing from R&D to mass production.

Core Functions and Technical Highlights

Accurate short circuit simulation

Dual-mode triggering:

Static compression: simulate short circuit caused by poor electrode contact through precision probe (pressure range 0~50N).

Dynamic pulse: Output 0~1000A programmable current pulse to reproduce sudden short-circuits under drop, squeeze and other scenarios.

Response speed: ≤1ms, complete capture of short-circuit transient characteristics (voltage dips, current spikes).

Full-parameter real-time monitoring

Temperature: Distributed fiber optic temperature measurement (±0.1℃ accuracy, support 16 channels synchronous acquisition).

Pressure: piezoresistive sensor (0~30MPa range, detecting battery expansion force and leakage risk).

Voltage/Internal Resistance: High-speed sampling (≥10kHz), recording the changes of electrical characteristics during the whole process of short-circuit.

Intelligent safety protection

Three-level interlocking mechanism:

① Hardware level: 10μs level fuse + electronic circuit breaker, milliseconds to cut off dangerous current.

② Software level: temperature/pressure threshold real-time alarm (automatically terminate the test when the limit is exceeded).

③ Mechanical level: explosion-proof pressure relief valve (burst pressure set to 1.2 times the battery working pressure).

Inert gas protection: optional nitrogen purge function to isolate oxygen to inhibit the risk of combustion.

High compatibility design

Compatible battery types: cylindrical (18650/21700), square (soft pack/hard case), polymer batteries.

Size range: Minimum battery diameter 6mm x thickness 4mm, maximum support 50mm x 150mm battery module.
