Battery Packs

1. Overview

Battery packs are integrated assemblies of multiple electrochemical cells connected in series, parallel, or combination configurations to deliver required voltage, capacity, and power. These modular energy storage systems play critical roles in portable electronics, electric vehicles (EVs), renewable energy storage, and industrial equipment. Modern advancements in battery chemistry and management systems have enabled higher energy densities, faster charging capabilities, and improved safety features essential for expanding electrification across industries.

2. Major Types & Functional Classification

Type	Functional Characteristics	Application Examples
Lithium-ion (Li-ion)	High energy density (150-250 Wh/kg), 500-2000 cycles lifespan, low self-discharge	Smartphones, EVs, laptops
Nickel-Metal Hydride (NiMH)	Moderate energy density (60-120 Wh/kg), 500-1000 cycles, environmental friendly	Hybrid vehicles, digital cameras
Lead-Acid	Low cost, high surge currents, 300-500 cycles	Automotive starters, backup power
Solid-State	High safety, >1000 Wh/L energy density, wide temperature range	Next-gen EVs, aerospace
Lithium Polymer (LiPo)	Flexible form factors, 300-500 cycles, lighter weight	Drones, wearable devices

3. Structural Composition

Typical battery pack architecture includes:

Mechanical Components: Prismatic/cylindrical/smart cells, protective housing, electrical connectors, thermal management materials
Internal Technology: Anode/cathode materials (graphite/NMC/LFP), electrolyte (liquid/gel/solid-state), separator films
Electronic Systems: Battery Management System (BMS) with voltage monitoring, cell balancing, temperature sensors, communication interfaces (CAN/SMBus)

4. Key Technical Specifications

Parameter	Significance
Energy Density (Wh/kg)	Determines runtime/weight ratio for portable devices
Charge Cycle Life	Defines longevity under repeated charge/discharge
Voltage Range (V)	Dictates device power requirements
Charge Rate (C-rate)	Impacts charging time and thermal performance
Operating Temperature (-20 C to 60 C)	Determines environmental suitability

5. Application Domains
