# Industrial Specification: Electrical Testing Chamber

## 1. Technical Definition
A specialized enclosure within a battery testing system designed to safely conduct electrical performance and safety tests on lithium-ion battery modules.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1000 V DC, 0-500 A, -40°C to +85°C ambient**. Failure boundary: **Dielectric breakdown at 1500 V DC (3 kV/mm for air insulation), thermal runaway initiation at 120°C internal temperature, current overload at 550 A sustained for &gt;30 seconds**, Mechanism: **Paschen's Law breakdown in air gaps at 3 kV/mm electric field strength, Arrhenius equation kinetics for SEI decomposition at 120°C (activation energy ~1.5 eV), Joule heating (P=I²R) exceeding 15 kW thermal dissipation capacity**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
