The Evolution of the Ruichi EC31 and EC31L: DFSK’s Compact Electric Micro Truck Platform
The Ruichi EC31 and EC31L are compact battery-electric light commercial vehicles produced by Ruichi Automobile, a new-energy commercial brand associated with the Seres Group and the broader DFSK industrial ecosystem. Introduced in the early 2020s and continuing in production into the mid-2020s, the EC31 family represents one of the company’s most important entries into the small electric logistics truck segment.
Designed for urban delivery, last-mile logistics, and light-duty commercial transport, the EC31 and its long-wheelbase EC31L variant prioritize cargo efficiency, low operating costs, and maneuverability in dense city environments. Together, they form the foundation of Ruichi’s compact electric truck lineup and serve as a stepping stone between micro vans like the EC35 and larger platforms such as the EC75.
Origins and Development Background
The Ruichi EC31 platform was developed during a period of rapid electrification in China’s commercial vehicle industry. Cities were increasingly restricting combustion-engine delivery vehicles, creating strong demand for compact electric logistics trucks with higher payload capacity and lower emissions.
Ruichi, already active in electric vans, introduced the EC31 as a purpose-built micro truck designed to compete in the “urban freight” category. The EC31L followed as an extended and improved version, offering more cargo space and higher load capacity.
The EC31 family is closely related to DFSK’s broader light commercial engineering strategy, sharing design philosophy and components with other Ruichi and DFSK electric utility vehicles.
Production began around 2022 to 2023, and both EC31 and EC31L remain in active production today as part of Ruichi’s commercial EV portfolio.

Production Timeline
| Model | Years Produced |
|---|---|
| Ruichi EC31 | Early 2020s–present |
| Ruichi EC31L | Early 2020s–present |
Both versions belong to the same generation platform, with the EC31L acting as the long-wheelbase, higher-capacity evolution of the EC31.
Vehicle Classification and Role
The EC31 family is classified as a small electric cargo truck / micro logistics vehicle. Unlike passenger vans, it is designed strictly for goods transport, although some variants allow limited crew seating.
Primary use cases include:
- Urban courier delivery
- Small business logistics
- Market and supermarket supply transport
- Construction material hauling (light loads)
- Municipal short-distance operations
Its compact size allows it to operate in narrow city streets where larger vans are restricted.
Dimensions and Cargo Design
The EC31 and EC31L share a similar structural architecture but differ in cargo capacity and overall length.
Ruichi EC31 (standard version)
Key characteristics:
- Length: approximately 191 inches (about 4,855 millimeters)
- Width: about 65 inches (1,660 millimeters)
- Height: about 78 inches (1,985 millimeters)
- Wheelbase: approximately 120 inches (3,050 millimeters)
Cargo box size typically:
- About 120 inches by 62 inches by 14 inches (varies by configuration)
- Cargo volume: approximately 6.9 cubic meters in optimized configurations
Rated payload:
- Around 2,600 pounds (approximately 1,180 kilograms)
Ruichi EC31L (long-wheelbase version)
The EC31L expands the platform for higher cargo capacity and improved stability.
Key characteristics:
- Length: approximately 191 to 193 inches depending on configuration
- Width: about 65 inches (1,660 millimeters)
- Height: up to about 86 inches in taller variants
- Wheelbase: approximately 120 inches (3,050 millimeters)
Cargo box improvements:
- Larger reinforced cargo compartment
- Increased usable volume up to about 7 cubic meters
- Stronger chassis and reinforced rear axle system
Payload capacity:
- Up to approximately 2,600 pounds (around 1,185 kilograms) in standard configurations
The EC31L is engineered for heavier daily logistics workloads and higher utilization fleets.
Exterior Design Evolution
The EC31 family uses a purely functional design optimized for efficiency rather than aesthetics.
Key exterior features include:
- Box-shaped cargo body for maximum volume efficiency
- Vertical front fascia with simple aerodynamic shaping
- Wide-opening rear cargo doors for forklift access
- Sliding or hinged side access depending on configuration
- Reinforced steel body structure for load stability
The EC31L introduced subtle refinements such as:
- Improved front-end airflow design
- Slightly taller roof variants for expanded cargo options
- Reinforced side panels for durability in heavy-duty use
Overall, design changes across the EC31 lifecycle have focused on utility and cost optimization rather than visual redesign.
Powertrain and Electric System
Both EC31 and EC31L use similar electric drivetrain systems designed for reliability and low operating costs.
Core specifications:
- Permanent magnet synchronous motor
- Maximum output: approximately 60 kilowatts (about 80 horsepower)
- Torque: around 220 newton-meters
- Drivetrain: rear-wheel drive in most configurations
Battery system:
- Lithium iron phosphate (LFP) battery chemistry
- Capacity: approximately 38 to 39 kilowatt-hours
- Designed for long cycle life and fleet durability
Range:
- Approximately 180 to 190 miles under ideal conditions (about 295 kilometers CLTC cycle)
This range is optimized for daily urban delivery routes rather than long-distance travel.
Charging Performance
Charging capability is designed for fleet operations:
- DC fast charging: about 1 to 1.5 hours to 80 percent
- AC slow charging: approximately 6 to 8 hours full charge
- Depot charging compatibility for overnight fleet use
This allows operators to integrate the EC31 family into standard logistics schedules without significant downtime.
Interior Layout and Cabin Design
The EC31 and EC31L feature a simple two-seat cabin focused on utility.
Interior characteristics include:
- Two-seat front cabin layout
- Minimalist dashboard with essential controls only
- Durable materials designed for heavy daily use
- Basic infotainment or radio system depending on trim
- Air conditioning available in most versions
The cabin is intentionally simplified to maximize durability and reduce maintenance costs.
