Successful Cases
Liquid Cooling Optimization for Power Battery of New Energy Vehicles
Challenge
The power battery pack of a pure electric passenger car from a mainstream automaker has the problem of excessive internal temperature difference under 4C fast charging and high-low temperature operating conditions. During fast charging, the maximum temperature of the battery cells reaches 65℃, with a temperature difference of up to 8℃, which directly leads to a 7% decrease in fast charging efficiency, shortens the battery service life to 6 years/120,000 kilometers, results in a 20% winter range attenuation rate, and fails to meet the automaker’s 8-year/150,000-kilometer warranty standard.
Solution
Replace the original air-cooling system with an indirect liquid-cooling system, customize a high thermal conductivity aluminum alloy water-cooling plate, optimize the cooling liquid flow channel design through CFD thermal simulation technology, equip with an intelligent temperature control system, and optimize the pipeline layout while adding a leakage monitoring function to adapt to the complex operating conditions during vehicle driving.
Result
- The maximum temperature of fast-charging battery cells is reduced to 43℃, and the internal temperature difference is controlled within ≤2℃, which fully meets the industry’s precise temperature control standard of ±2℃
- The battery service life is extended to 8 years/150,000 kilometers, and the cycle life is increased from 800 times to 1100 times, which is consistent with the mainstream measured level of the industry
- The fast charging efficiency is increased by 7%, the winter range attenuation rate is reduced to 12%, and the comprehensive energy consumption of the whole vehicle is optimized by 5%
- Successfully passed harsh tests such as high-low temperature and leakage, the cooling system operates stably without any Performance degradation
Liquid Cooling Solution for Electric Drive System of New Energy Commercial Vehicles
Challenge
The electric drive system (motor + controller) of a certain electric heavy-duty truck generates concentrated heat under heavy-load and uphill operating conditions. The traditional oil-cooling solution has insufficient heat dissipation efficiency, leading to the maximum temperature of the motor stator reaching 110℃ and the IGBT module temperature reaching 105℃, an 8% attenuation in power output, 10 annual fault shutdowns, a service life of only 4 years for the electric drive system, and high maintenance costs.
Solution
Adopt oil-water combined cooling solution. The motor stator uses water jacket cooling, and the rotor adopts precise oil spray cooling to jointly boost heat dissipation.
The controller is fitted with vacuum brazed cold plates for accurate heat dissipation. Optimize flow channel design and integrate operation monitoring system. Eco-friendly cooling liquid is applied to greatly cut maintenance frequency.
Result
The temperature of the motor stator is reduced to 95℃, and the temperature of the IGBT module is reduced to 90℃, both below the safe operation threshold, completely solving the overheating hidden danger
The power output attenuation is controlled within ≤2%, the number of annual fault shutdowns is reduced to 1, saving USD1,000 in annual maintenance costs, which is in line with the actual operation needs of commercial vehicles
The service life of the electric drive system is extended to 6 years/250,000 kilometers, the energy efficiency conversion rate is increased to 94%, and the range under heavy-load conditions is increased by 8%
Liquid Cooling Upgrade for Domain Controller of Intelligent Connected Vehicles
Challenge
The chip heat generation of the domain controller of a certain L3-level intelligent connected vehicle has surged. The traditional air-cooling solution has insufficient heat dissipation capacity, leading to the chip operating at a high temperature of ≥83℃ for a long time, resulting in problems such as 10% computing power frequency reduction and increased response delay, an annual failure rate of 4.8%, and the noise of the air-cooling fan affecting riding comfort
Solution
Adopt a direct-contact liquid-cooling solution, customize a microchannel cold plate to directly attach to the core heating components of the domain controller, optimize the structural design to improve heat exchange efficiency, equip with a low-noise electronic water pump and intelligent temperature control algorithm, and simplify the installation and later maintenance processes.
Result
The maximum temperature of the chip is reduced to 60℃, and the temperature fluctuation is controlled within ≤2℃, which fully meets the optimal operating temperature range of the chip
- Completely solve the problem of chip computing power frequency reduction, shorten the response delay, increase the operating efficiency by 10%, reduce the annual failure rate to 0.5%, and the data is consistent with the industry measured standards
The operating noise of the liquid-cooling system is ≤22dB, which effectively improves riding comfort, the load capacity of the domain controller is increased by 18%, and it can support the expansion of higher-level autonomous driving functions
