“Traditional” vs “New” Thermal Management The transition from traditional fuel vehicles to modern new energy vehicles has significantly impacted the complexity of vehicle thermal management systems. Originally simple, these systems have evolved into intricate structures, progressing from standalone modules to integrated systems engineering. Traditional thermal management primarily involves air conditioning and powertrain systems. In contrast, new energy vehicles incorporate the power battery system into the thermal management scope, marking a shift towards ‘new’ thermal management. This article focuses on key components within both traditional and new thermal management systems. In traditional systems, we highlight the condenser, evaporator, radiator, oil cooler, and intercooler. For new thermal management, the spotlight is on the battery cooling plate. The distinction between ‘traditional’ and ‘new’ does not imply that traditional thermal management is ineffective. Instead, it underscores that new thermal management technologies are advancing at an unprecedented pace. This rapid development is driven by the unique demands and challenges posed by new energy vehicles, necessitating more sophisticated and efficient thermal management solutions. Table of Contents Traditional Thermal Management Condenser The condenser is an integral component of the vehicle’s air conditioning (A/C) refrigerant circuit. It connects to the A/C compressor and the receiver-drier via copper and aluminium pipes. Typically installed in front of the car’s radiator, it often shares a cooling fan with the radiator. Based on the type of coolant used, condensers can be classified into four types: water-cooled, air-cooled, water-air cooled (including evaporative and spray types), and those cooled by refrigerant evaporation or other process media. During operation, the condenser cools high-pressure, high-temperature refrigerant into a high-pressure, low-temperature liquid. This liquid then passes through a capillary tube, vaporising into the evaporator to continue the cooling cycle. As this process releases heat, the condenser usually operates at a high temperature, categorising it as a type…

High-Voltage Fast Charging with Battery Liquid Cooling Tech High-voltage fast charging is a technology primarily used in electric vehicles and some mobile devices. It works by increasing the voltage above conventional levels, delivering energy to the battery at a faster rate. This significantly reduces charging time and enhances device efficiency. However, not all devices support this technology, and using it with incompatible devices can cause overheating and damage. Ensuring compatibility is crucial before using high-voltage fast charging. Table of Contents Development status of high-voltage fast charging The demand for efficient charging solutions is growing alongside the increase in new energy vehicle ownership. High-voltage fast charging, seen as the future mainstream method, addresses this need. By 2025, the global penetration of 800V models is expected to reach 13%. This platform involves multiple segments, including vehicles, charging piles, and batteries, aiming to improve charging efficiency and advance new energy vehicle technology. Why is Battery liquid cooling necessary? High-voltage fast charging (HVFC) is playing a transformative role in electric vehicles, but it also poses a major challenge – heat generation. During fast charging, battery cells generate a lot of heat, which must be dissipated efficiently to ensure safe and stable charging. This requires a cooling system at the PACK level. Battery thermal management systems utilize three common cooling methods. Air cooling is the simplest and most cost-effective method, utilizing natural or fan-assisted low-temperature air to dissipate heat from the battery cells. However, due to its low heat exchange efficiency and poor temperature uniformity, it is typically used in early electric passenger cars and A00 models. The second method is the cold plate cooling method, in which a cooling plate is placed at the bottom or side of the battery cell. The plate uses a liquid or refrigerant to carry away the heat.
