Types of HV Batteries: From NiMH to Lithium-Ion


HV batteries have come a long way, evolving from the initial Nickel Metal Hydride (NiMH) batteries to the dominant Lithium-Ion batteries used in modern EVs and hybrids. NiMH batteries paved the way for mass-produced hybrids, but the continuous advancements in technology led to the emergence of Lithium-Ion batteries as the industry standard. These cutting-edge batteries offer impressive range and higher voltage levels, delivering a more exhilarating and powerful driving experience. With their extended capabilities, Lithium-Ion batteries have revolutionized the world of electric vehicles, propelling us towards a sustainable future.


Cooling Systems: Battling the Heat


Efficient cooling is paramount when it comes to HV batteries, especially in regions with scorching climates like South Florida. Each automaker has devised its own unique cooling system to combat the challenge of heat management. Let's take a closer look at some innovative approaches:


  1. Natural Cooling: The Nissan Leaf relies on the ingenious concept of natural cooling. Through cleverly designed air channels, ambient air circulates over the battery, dissipating heat naturally. This eco-conscious cooling method harnesses the power of nature to keep the battery operating at optimal temperatures.


  1. Blower Fan Technology:The Prius and Ford Fusion models employ blower fans to regulate temperature. These fans ensure proper airflow, preventing overheating and maintaining ideal conditions for the HV battery to perform at its best.


  1. Liquid Coolant Systems:The Chevy Volt takes a different route, utilizing a liquid coolant system. This system circulates coolant throughout the battery, effectively dissipating heat and maintaining stable temperatures. By efficiently managing heat, the Volt's battery maintains peak performance even during demanding driving conditions.


  1. Refrigerated Cooling Innovation: The BMW i3 breaks new ground with its pioneering design. It incorporates a refrigerated cooling system that utilizes the same refrigerant as the AC system. This cutting-edge approach ensures the HV battery remains cool, allowing for optimal performance and longevity.



Weight and Suspension Considerations


HV batteries vary significantly in size and weight. For example, a Tesla Model S High Voltage battery weighs over 1,200 lbs and is located beneath the vehicle, below the driver's side door. In contrast, the battery of a 2010 Nissan Altima weighs a mere 16 lbs. Such a substantial weight difference places increased stress on the front suspension of the vehicle. Therefore, regular inspections of the front suspension components are essential to detect any signs of excessive play or damage. Additionally, Tesla models often require more frequent replacement of low rolling resistance tires, necessitating proper alignment to ensure a smooth and safe ride.


Prioritizing HV Battery Maintenance


Owning a hybrid or EV offers exceptional fuel economy and performance, but it is vital to ensure that your High Voltage battery receives proper cooling and maintenance. At our ASE Certified facility, we offer comprehensive Hybrid and EV battery services for all major makes and models.
