In the realm of new energy vehicles, electrochemical energy storage batteries are the heart of the power system, enabling the transition from traditional internal combustion engine vehicles to electric and hybrid vehicles. For pure electric vehicles (EVs), the battery pack is the sole source of power for the vehicle's propulsion system. High - energy - density electrochemical batteries, such as lithium - ion batteries, are widely used due to their ability to store a large amount of electrical energy in a relatively compact and lightweight package.

These batteries power the electric motor, which drives the wheels of the vehicle. The performance of the battery, including its capacity, energy density, and charging speed, directly affects the vehicle's range, acceleration, and overall usability. For example, advancements in lithium - ion battery technology have led to EVs with ranges exceeding 400 miles (around 640 kilometers) on a single charge, making them more practical for daily use and long - distance travel.

In hybrid electric vehicles (HEVs) and plug - in hybrid electric vehicles (PHEVs), electrochemical energy storage batteries work in conjunction with an internal combustion engine. In HEVs, the battery is used to assist the engine during acceleration and to capture energy through regenerative braking, which converts the kinetic energy of the vehicle into electrical energy and stores it in the battery. This improves the vehicle's fuel efficiency and reduces emissions. PHEVs, on the other hand, have a larger battery capacity and can be charged from an external power source. They can operate in pure electric mode for a certain distance, typically ranging from 20 to 50 miles (about 32 to 80 kilometers), before the internal combustion engine kicks in, further reducing fuel consumption and emissions.

The development of fast - charging technology for electrochemical batteries in new energy vehicles is also a key area of focus. With the goal of reducing charging times to levels comparable to refueling a traditional vehicle, research and development efforts are aimed at improving battery chemistry, charging infrastructure, and battery management systems. Additionally, recycling and reuse of used vehicle batteries are becoming increasingly important. These batteries, even after their automotive service life, may still have sufficient capacity for other applications such as stationary energy storage, which helps to reduce waste and the environmental impact of battery production.
