What payment methods do you accept?

We accept payment by Bank Wire Transfer (TT) and Letter of Credit (LC). Our standard terms are 30% deposit and 70% payment before vehicle shipment. Full payment is required before delivery.

How to track vehicle information during transportation?

Once the vehicle is purchased, we will provide you with a tracking number and our team will keep in touch with the shipping team every day to inform you of the shipping status of the vehicle.

How to ensure the quality of cars?

Before the vehicle leaves the factory, we will conduct a strict factory inspection, display the detailed components of the vehicle through pictures and videos, and provide a complete quality inspection report to ensure that every exported vehicle is of the best quality.

How long does it take to ship the vehicle after ordering it?

After the vehicle is purchased successfully, it takes about 4-6 weeks to transport it from China to different ports. In addition, the customs clearance time will vary according to the policies and actual conditions of each country, which may increase the total transportation time.

Thermal Management and Performance Optimization of New Energy Vehicles (NEVs) in Extreme Climates

2026-07-08

1. The Environmental Challenge

Environmental challenges affecting lithium-ion battery performance in extreme cold and heat for NEVs.

Lithium-ion batteries perform optimally between 20°C and 40°C. Operating outside this range compromises vehicle efficiency. Extreme cold increases internal resistance and cabin heating demands, while extreme heat can reduce energy storage capacity and accelerate degradation. Explore our Industry News Blog for more market-specific insights.

2. Technical Solutions: Advanced Thermal Ecosystems

Rongwei Car International Trading Co., Ltd. technical solutions for advanced thermal ecosystems including active cooling and heat pumps.

To bridge the gap between high-quality Chinese manufacturing and international demands, Rongwei Car International Trading Co., Ltd. prioritizes vehicles equipped with advanced thermal ecosystems:

Active Cooling/Heating: Using coolant circuits to stabilize battery temperatures during fast-charging or high-load driving.
Heat Pumps: Significantly preserving range by moving energy efficiently rather than using resistive heating.
Component Integration: Scavenging waste heat from motors to warm the cabin or battery.
