Okay, I need to create a Wikipedia-style document about PHEV (Plug-in Hybrid Electric Vehicle) under the categories of Technology → Automotive → Electric Vehicles. Let me start by understanding what exactly is required here.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and maybe references or related documents. The content needs to be accurate, objective, detailed enough, easy to read, and use technical terms with explanations. Also, markdown formatting with proper hierarchy, lists, tables, code blocks if needed, and the document should be at least 800 characters long.

Starting with the title: "PHEV" as H1. Then an overview section explaining what PHEVs are. Next sections could include how they work, advantages/disadvantages, comparison with other EVs, market trends, etc. Maybe also a section on technology and components, or environmental impact.

I should make sure to define terms like "plug-in hybrid" clearly. Mention the two power sources: internal combustion engine and electric motor. Explain the battery capacity and charging methods. Compare PHEVs with regular hybrids (HEVs) and fully electric vehicles (BEVs). Highlight benefits like reduced fuel consumption, lower emissions, but also mention drawbacks such as higher cost, longer charging times, and limited all-electric range.

Including a section on technology: components like the battery system, powertrain, regenerative braking. Maybe a table comparing PHEV with HEV and BEV in terms of range, charging, fuel efficiency, etc. Also, discuss market trends, leading manufacturers, government incentives, and challenges.

Need to check for accuracy. For example, PHEVs typically have larger batteries than HEVs but smaller than BEVs. They can be charged via external sources, unlike HEVs which rely on regenerative braking. Mention specific examples like the Toyota Prius Plug-in or Chevrolet Volt.

Make sure each section is detailed enough. Maybe add a subsection under "How PHEVs Work" explaining the different modes: electric-only, hybrid, and engine-only. Also, discuss charging infrastructure and how it affects usability.

In terms of references, maybe include sources like EPA guidelines, industry reports, or manufacturer data. But since this is a wiki-style document, perhaps just mention key points without specific citations unless required.

Avoid markdown in the thinking process but ensure the final answer uses proper formatting. Check for technical terms: "regenerative braking," "battery capacity," "charging infrastructure." Explain them briefly if needed.

Ensure the document flows logically from introduction to detailed sections, then to market and future outlook. Keep paragraphs concise, use bullet points where appropriate. Make sure it's over 800 characters. Let me start drafting each section step by step.
