EV Charger Factory Financial Model

Key Financial Metrics for an EV Charger Factory

This financial model represents the operations of an Electric Vehicle (EV) Charger Manufacturing Factory, which designs, produces, and sells both complete charging systems and associated parts and components. The model projects 5–10 years of financial performance, based on production capacity, product mix, pricing strategy, market growth, and capital structure.

The model is divided into several key modules:

1. Revenue Module (80 Product Lines + Turnkey Systems)

2. Cost Structure (COGS, labor, overhead, materials, logistics)

3. Operating Expenses (R&D, SG&A, marketing, etc.)

4. Depreciation and CapEx schedule

5. Working Capital

6. Financing (Debt & Equity)

7. Taxation

8. Output Statements:

   • Income Statement

   • Cash Flow Statement

   • Balance Sheet

   • KPIs and Ratios

Revenue Module

Product Line Example Structure (80 SKUs)

The model incorporates 80 separate product lines, grouped into categories:

• DC Fast Chargers (10 models) — 50 kW, 100 kW, 150 kW, 350 kW variants

• AC Chargers (15 models) — residential, fleet, and workplace units

• Charging Modules (10 models) — power electronics modules, converters

• Cables and Connectors (8 models) — Type 1, Type 2, CCS, CHAdeMO, etc.

• Payment & Control Systems (7 models) — smart control panels, metering systems

• Software Licenses (5 models) — cloud management, billing, analytics tools

• Replacement Parts (15 models) — fuses, boards, transformers, internal wiring, relays

• Accessories (10 models) — mounting kits, housings, pedestals, branding panels

Each SKU line includes:

• Unit price (wholesale, retail)

• Monthly/annual sales volume

• Production cost per unit

• Gross margin per SKU

• SKU contribution to total sales

• Expected annual growth rate

• Product life cycle (launch–maturity–decline)

• Regional split (domestic/export)

• Warranty/return rates

• Spare part attachment rate

A consolidation sheet aggregates SKU-level revenue and cost data into total product group revenues.

Revenue Drivers

• Sales Volume is driven by factory capacity utilization, industry demand forecasts, and market penetration assumptions.

• Average Selling Price (ASP) is modeled to decline slightly each year due to competition and scale effects.

• Parts Sales grow in proportion to installed base of chargers (e.g., 3–5% of cumulative chargers sold require replacement parts per year).

• Aftermarket Service Revenue grows as the installed base expands.

Cost of Goods Sold (COGS)

COGS is calculated per product family:

• Raw Materials: Metal enclosures, copper cabling, semiconductors, transformers, cooling systems, printed circuit boards.

• Direct Labor: Assembly, testing, quality control.

• Factory Overhead: Utilities, maintenance, indirect staff, consumables.

• Freight & Packaging: Outbound logistics and protective packaging.

• Warranty Expense: Percentage of sales (1–2%) set aside for replacements or service.

The COGS schedule ties to production volumes and cost efficiency improvements over time (e.g., 2–3% annual cost reduction via economies of scale).

Operating Expenses

R&D Expense

Ongoing design and innovation, modeled as a percentage of revenue (typically 4–6%), front-loaded in early years for new charger designs.

Sales & Marketing

Sales commissions, trade shows, digital marketing, distributor support — modeled as a fixed + variable cost based on revenue.

General & Administrative (G&A)

Includes salaries for management, accounting, legal, and HR, plus insurance, rent, IT systems, and professional services.

Depreciation & Amortization

Linked to CapEx schedule and intangible assets (e.g., software IP, patents).

Capital Expenditures (CapEx)

The CapEx schedule includes:

• Factory Setup: Buildings, assembly lines, robotics, QC systems.

• Machinery & Equipment: Soldering stations, testing rigs, automation.

• Tooling & Molds: For housings and connectors.

• Software Development: Production monitoring, ERP integration.

• Expansion Phases: Additional lines added as capacity utilization exceeds 85%.

CapEx drives depreciation (straight-line or accelerated) over useful lives:

• Buildings: 20 years

• Equipment: 10 years

• Tooling: 5 years

• Software: 3–5 years

Financing & Taxation

Debt

Model includes long-term loans for factory buildout and equipment, with interest expense tied to principal balance and amortization schedules.

Equity

Equity injections fund initial CapEx; dividends can be modeled as a payout ratio of net income.

Taxes

Effective tax rate modeled (e.g., 25%) after accounting for depreciation, interest, and R&D credits.
