Revolutionary Replenishment Experience
At the core of the Oshan 520’s disruptive power lies its 56 kWh LFP battery pack – featuring CATL’s modular design perfectly compatible with chocolate battery swap stations . When the vehicle enters the swap position, robotic arms precisely remove and replace the 415 kg battery pack within 120 seconds, ten times faster than traditional fast charging .
This design directly addresses EV owners’ pain points: no more competing for charging piles at highway service areas, no worries about depreciation caused by battery degradation. Under the battery-body separation model, users can choose not to purchase the battery, lowering the purchase threshold through leasing arrangements while enabling more flexible future battery upgrades .
CATL’s infrastructure ambitions provide solid backing: 1,000 battery swap stations will be built in 2025, ultimately weaving a nationwide network of 30,000 swap stations . This means the Oshan 520’s replenishment convenience will grow exponentially over time.
Design Language
At first glance, you’ll recognize the elegant genes of the Changan Yidong, yet discover new ideas in the details. The front features a boundless grille design with ripple-like outward-expanding lines, paired with the new Changan Oshan emblem, showcasing its electric identity while retaining dynamic aesthetics .
The side profile abandons exaggerated hidden door handles, returning to traditional mechanical structures to avoid freezing hazards in northern winters – a testament to its respect for practicality3. A straight waistline runs through the body, extending to the full-width LED taillights that create a star-track-like illumination at night, enhancing recognition .
The body dimensions strike a careful balance between space and handling: 4770mm length, 1840mm width, and 2765mm wheelbase provide families with spacious rear seating while maintaining the compact sedan’s agility . The chrome exhaust decoration at the rear, though an “electric bluff,” skillfully reconciles the futuristic feel of EVs with traditional drivers’ aesthetic preferences.
Cabin Philosophy
Inside, Oshan 520’s “technology democratization” philosophy is immediately apparent. Dual 10.25-inch screens (digital instrument cluster + central display) form the information hub, with clear interface logic and quick response, avoiding over-design that could distract driving focus . The dashboard uses soft-touch materials with fine stitching, breaking the hard plastic convention of entry-level models.
Comfort features are segment-defying: heated/ventilated front seats become salvation during southern heatwaves or northern winters; automatic climate control with rear vents ensures cabin-wide temperature balance; 360-degree camera with parking radar makes tight-space maneuvers effortless .
Space planning demonstrates family wisdom. The 2765mm wheelbase translates to generous rear knee room, while the flat floor enhances comfort for middle-seat passengers. Though trunk volume isn’t specified, the bottom-mounted battery pack avoids encroaching on cargo space, meeting family weekend shopping or travel luggage needs.
Performance Analysis
The Oshan 520 doesn’t blindly pursue brutal acceleration, instead focusing on efficiency and practicality. Its TZ180XS001 motor manufactured by Chongqing Qingshan delivers 105kW (143hp) maximum power and 190N·m peak torque . Power output is linear and direct, with brisk 0-50km/h acceleration that handles urban congestion with ease. The top speed is limited to 135km/h, satisfying legal requirements.
The 56kWh battery achieves 515km CLTC range – sufficient for intercity commutes (Shanghai-Hangzhou roundtrip without charging) or a week of Beijing-Tianjin commuting . Real-world tests show about 85% range realization in normal temperatures, with 20% redundancy recommended in winter – still mainstream for its class.
The suspension tuning leans toward comfort. The front MacPherson and rear multi-link setup filters road imperfections decently, effectively controlling body sway when traversing broken pavement. Steering feel is light while retaining moderate feedback, paired with ESP stability control + blind spot monitoring to balance agility and stability . Test drivers note: “The chassis absorbs bumps calmly, stays planted during highway lane changes – rare driving engagement in family-oriented positioning” .
Market Competitiveness
In the RMB 160,000 pure electric sedan battlefield, Oshan 520 carves differentiation with its “exclusive battery swap capability”. Competitive analysis reveals its disruptive logic:
BYD Qin PLUS EV: Strong brand recognition, but fast charging exceeds 30 minutes with no battery upgrade path
GAC Aion S Plus: Similar range, but battery-binding model leads to higher depreciation
NIO ET5 (with rental options): Comparable swap experience, but entry price still RMB 100,000+ higher
The Oshan 520 precisely targets two user groups: ride-hailing drivers who value time-as-money (2-minute swaps save 1+ hour for 4 extra daily orders); family secondary car buyers needing anxiety-free weekend trips with lower entry cost via battery separation .
The pricing strategy is more aggressive. At RMB 166,800, it penetrates the mainstream family sedan territory. Choosing battery leasing could lower the down payment below RMB 120,000 – cheaper than equivalent ICE cars .
As the sun sets, an Oshan 520 glides into a swap station. Robotic arms dance – removing the tired battery, lifting a fresh energy block. Within two minutes, it re-enters the traffic flow, taillights drawing a stream of light.
This isn’t sci-fi imagination, but daily life under CATL’s blueprint of 30,000 swap stations . The Oshan 520’s value lies not at the top of spec sheets, but in urban rhythms – when a ride-hailing driver smiles from extra orders saved by charging time, when young families take weekend trips without range anxiety. Pragmatic technology has then fulfilled its mission .
