OEM battery pack specs for various vehicles encompass the specifications and characteristics of battery packs used by different manufacturers. These specs include battery capacity, voltage, energy density, and more. Understanding these specifications helps in comparing and choosing the right battery pack for specific vehicle models.
  1. Battery Capacity and Voltage: OEM battery pack specs include information about the battery capacity, which refers to the amount of energy the battery can store, and the voltage, which determines the electrical potential difference. These specifications play a crucial role in determining the range and performance of electric vehicles.
  2. Energy Density: Another important factor to consider is the energy density of the battery pack. Energy density refers to the amount of energy stored per unit of volume or weight. Higher energy density allows for longer driving ranges and improved overall performance.
  3. Other Relevant Details: OEM battery pack specs may also include additional details such as charging capabilities, cycle life, warranty, and safety features. These details help consumers make informed decisions when choosing the right battery pack for their specific vehicle requirements.

The biggest disadvantage of lithium-ion batteries is their susceptibility to thermal runaway, which can lead to overheating or fires if not properly managed. Additionally, they can be more expensive upfront compared to traditional lead-acid batteries and require specific charging equipment.
What shortens the life of lithium batteries?
Factors that shorten the life of lithium batteries include excessive heat, overcharging, deep discharging below recommended levels, high discharge rates, and poor-quality chargers. Regular maintenance and proper charging practices can help extend their lifespan significantly.

The title of the number one lithium battery manufacturer often goes to CATL (Contemporary Amperex Technology Co., Limited), known for its significant market share in electric vehicle (EV) battery production. Other leading brands include LG Chem, Panasonic, and Samsung SDI, recognized for their quality and innovation.

The battery is equipped with a smart Battery Management System (BMS) rated at 250A, which monitors critical parameters such as overcurrent, overcharging, and overheating, providing protection against potential hazards and ensuring safe operation.

Absolutely! We accommodate custom requirements, including thickness, width, color, and surface finishes (such as brushed, mirror, or colored coatings). Share your specific needs, and we’ll provide you with the best solution.

As China’s largest private exporter of stainless steel, we offer unmatched production capacity and extensive experience in global markets. We prioritize customer satisfaction, providing high-quality products, flexible cooperation models, and prompt, reliable services to ensure your success.
