Battery condition is the single most important — and most expensive — variable in a used EV. Ask for a State of Health (SOH) report: in China, dealers and authorized service centers can read it via the manufacturer diagnostic system. It shows remaining capacity as a percentage of the original. Rule of thumb: above 90% is excellent, 85-90% is acceptable for the price, below 80% needs a serious price cut or battery refurbishment. Also get the battery's full charge and discharge history (次数) — a 3-year-old car with 800 fast-charge cycles has lived a harder life than one with 200. Physically, inspect the battery pack enclosure on a lift for dents, corrosion, or coolant leaks. Check that DC fast charging works during a test charge. Finally, verify the battery is not covered by an open recall or replacement program — this is both a risk and sometimes a free upgrade.

Pure electric vehicles are classified as Class 9 Dangerous Goods due to their large lithium batteries, leading to strict shipping regulations. Shipping companies have high requirements for the loading position and fire isolation measures for dangerous goods, and some roll-on/roll-off ships refuse to accept used EVs. As a result, EVs often require more expensive special container shipping and incur additional handling fees for hazardous materials.

Both are common, and the right choice depends on budget and destination: 1. Container shipping (20ft/40ft): The car is sealed inside a container, offering better protection and allowing you to load spare parts inside the car. Typical cost from Shanghai to major world ports: $1,500-$3,000 per car. Best for long distances and high-value vehicles. 2. RoRo (roll-on/roll-off): The car is driven onto the ship and secured on deck. Cheaper ($800-$1,800 to most ports) and faster to load, but exposed to weather and port handling. Not all routes offer RoRo service. Transit time examples: to the Gulf 15-25 days, to West Africa 30-45 days, to Latin America 25-40 days, to Europe 20-35 days. Ask your exporter which option serves your destination port, and always insure the shipment for full value.
