Introduction to the 2002 Ford Think: A Pioneer in Electric Mobility

The 2002 Ford Think stands as a bold, if underappreciated, chapter in the history of electric vehicles (EVs). As one of the first mass-produced electric cars from a major automaker, it offered a glimpse into a future where zero-emission driving wasn’t just a dream. With its compact design, city-friendly range, and innovative battery technology, the Think (originally developed by Norwegian company Pivco before Ford’s acquisition) was a trailblazer in the early 2000s EV landscape. Though its production run was short-lived, the 2002 Ford Think remains a cult favorite among EV enthusiasts and DIY mechanics alike.

For owners and restorers of this vintage electric gem, understanding its unique component ecosystem is critical. Unlike conventional gasoline-powered cars, the Think relies on a specialized network of parts—from high-voltage battery packs to regenerative braking systems. This guide dives deep into the 2002 Ford Think electric car parts, offering practical advice for repairs, replacements, and even upgrades. Whether you’re troubleshooting a failing charger or aiming to modernize your vehicle’s performance, this resource will help you navigate the quirks of this early EV with confidence.

Understanding the Core Components of the 2002 Ford Think

Before diving into specific parts, it’s essential to grasp the architecture of the 2002 Ford Think. This EV operates on a 288V DC system with a lead-acid battery pack (later models experimented with NiMH). Its simplicity compared to modern EVs makes it ideal for DIY projects, but its aging design also introduces unique challenges. Below are the critical systems and their key components.

Battery Pack: The Heart of the Vehicle

The 2002 Ford Think’s battery pack is its most vital—and most problematic—component. Original models used 24 12V lead-acid batteries (288V total), arranged in a tray under the vehicle floor. These batteries are heavy (over 1,000 lbs) and prone to sulfation and capacity loss over time.

• Common Issues: Voltage imbalances, reduced range (original: 50–80 miles per charge), and premature failure.
• Replacement Options:
  • Lead-acid (e.g., Trojan T-1275): Affordable but short lifespan (~3–5 years).
  • AGM (Absorbent Glass Mat): Better vibration resistance and longevity.
  • Li-ion retrofit kits: High-cost but offer 2–3x range and 10+ year lifespan.
• Tip: Always check individual cell voltages before replacing the entire pack. A single weak cell can drag down the entire system.

Motor and Controller

The Think uses a 29 kW (39 hp) permanent magnet DC motor paired with a Curtis 1231C-8601 motor controller. This setup delivers smooth acceleration but can overheat under sustained load.

• Motor Care: Inspect brushes and commutators annually. Replace if worn beyond 1/4 inch.
• Controller Diagnostics: Use a Curtis Programmer to check error codes (e.g., “Overtemp” or “Undervoltage”).
• Upgrade Path: Swap to a higher-efficiency AC motor (e.g., NetGain Hyper 9) for improved torque and regenerative braking.

Onboard Charger and DC-DC Converter

The Think’s 1.5 kW onboard charger (rated for 120V/240V) and 300W DC-DC converter are prone to capacitor failure. The DC-DC converter powers the 12V auxiliary system (lights, wipers, etc.).

• Symptoms of Failure: Charging interruptions, dim lights, or a dead 12V battery.
• Repair Tip: Replace electrolytic capacitors in the charger with high-temp (105°C) variants.

Common 2002 Ford Think Electric Car Parts Failures and Fixes

Even with meticulous care, the 2002 Ford Think’s aging design leads to predictable failures. Below are the top issues and their solutions, backed by real-world owner experiences.

Battery Management System (BMS) Limitations

The original BMS is rudimentary—it lacks cell-level monitoring, leading to imbalanced charging. Many owners report “false full charge” indicators or sudden power loss.

• Solution: Install an aftermarket BMS (e.g., Orion Jr. or Thunderstruck) for real-time cell monitoring and balancing.
• Example: A 2002 Think owner in California reduced battery replacement costs by 40% after adding an Orion BMS.

Regenerative Braking System

The Think’s regenerative braking is weak compared to modern EVs. Worn brake pads or a failing motor controller can disable it entirely.

• Diagnosis: Test braking force in “B” (braking) mode. A healthy system should decelerate at ~0.2g.
• Fix: Replace brake pads with ceramic compounds (e.g., Bosch QuietCast) to reduce dust and improve regen efficiency.

HVAC System: Heating and Cooling

The Think lacks a heat pump. Instead, it uses a resistive heater (5 kW) for cabin warmth, which drains the battery rapidly. Cooling relies on a 12V electric fan.

• Upgrade Options:
  • Install a 12V PTC heater (e.g., Webasto) for pre-heating.
  • Add a rooftop solar panel (100W+) to offset HVAC load.
• Tip: Use a thermal blanket (e.g., EV Blanket) to insulate the battery pack in winter.

Where to Source 2002 Ford Think Electric Car Parts

Sourcing parts for a 20-year-old EV can feel like a scavenger hunt. While OEM components are scarce, a mix of salvage yards, specialty vendors, and aftermarket solutions fills the gap.

OEM and Salvage Parts

Original Ford Think parts are rare but not extinct. Key sources include:

• Salvage Yards: Check Car-Part.com or eBay Motors for “Ford Think” listings. A complete battery tray (minus batteries) can cost $500–$1,000.
• Ford Dealers: Some still stock legacy parts. Request a Ford P/N lookup for components like the DC-DC converter (P/N: 1C2Z-10B687-AA).

Aftermarket and Retrofit Solutions

The EV community has developed robust alternatives for discontinued parts:

• Batteries:
  • Thunderstruck Motors: Li-ion retrofit kits ($3,500–$5,000).
  • Green Shed: AGM replacements ($1,200 for full set).
• Controllers: Curtis Instruments still supports 1231C controllers with firmware updates.
• Chargers: Elcon 3.3 kW chargers ($400) are drop-in replacements.

3D Printing and Custom Fabrication

For broken plastic components (e.g., dashboard trim or battery covers), 3D printing is a game-changer. Sites like Thingiverse offer user-submitted designs for Think parts.

• Example: A 3D-printed gear shift knob (PLA filament) costs $15 vs. $80 for a used OEM part.

DIY Upgrades to Enhance Performance and Longevity

The 2002 Ford Think’s open architecture invites creativity. These upgrades can transform it into a modern, efficient EV while preserving its vintage charm.

Battery Technology: Lead-Acid to Lithium-Ion

Replacing lead-acid with Li-ion is the most impactful upgrade. Benefits include:

• 2–3x range increase (150+ miles with a 20 kWh pack).
• 50% weight reduction (~500 lbs lighter).
• 10+ year lifespan (vs. 3–5 years for lead-acid).

Implementation:

• Use a Thunderstruck Motors Li-ion kit (includes BMS, charger, and wiring).
• Reposition batteries to the front trunk (reduces center of gravity).
• Install a battery heater for cold climates.

Motor and Controller Upgrades

Swap the original DC motor for an AC motor (e.g., NetGain Hyper 9) to gain:

• Higher efficiency (85% vs. 75% for DC).
• Stronger regenerative braking.
• Compatibility with modern controllers (e.g., Curtis 1239E).

Tip: Pair the AC motor with a Zilla controller for programmable performance profiles.

Charging Infrastructure

The original 1.5 kW charger takes 8–12 hours for a full charge. Modernize with:

• Level 2 Charger: Install a 6.6 kW charger (e.g., ClipperCreek HCS-40) for 3–4 hour charging.
• Portable Charger: Keep a 3.3 kW Elcon charger in the trunk for emergencies.
