Lead-acid battery for electric vehicles

Lead-acid batteries for electric vehicles (EVs) are traditionally used in applications like golf carts, forklifts, and low-speed vehicles. Although newer technologies like lithium-ion are now the standard for modern EVs, lead-acid batteries remain relevant in some areas due to their low cost and robust performance in certain use cases.

Types of Lead-Acid Batteries for EVs:

Flooded Lead-Acid Batteries:

Traditional design with removable caps for maintenance.
Cost-effective but requires regular electrolyte refilling and maintenance.

Sealed Lead-Acid Batteries (VRLA):

Absorbed Glass Mat (AGM): Offers improved performance, higher energy density, and longer life compared to flooded types.

Gel Batteries: Uses a gel-like electrolyte, ideal for deep discharge applications with better resistance to vibration and temperature extremes.

Deep Cycle Lead-Acid Batteries:

Specifically designed to provide sustained energy over longer periods (as opposed to short bursts of high power).
Ideal for electric vehicles requiring consistent power, such as golf carts or industrial EVs.

Key Features:

Cost-Effectiveness:

One of the most affordable options for energy storage in electric vehicles.

Robustness:

Lead-acid batteries for electric vehicles Can tolerate mechanical abuse and overcharging better than some advanced battery chemistries.

Recyclability:

Nearly 99% of lead-acid batteries are recyclable, making them an eco-friendly option when properly managed.

Readily Available:

Widely manufactured and accessible globally.

Advantages:

Low Initial Cost:
Much cheaper than lithium-ion batteries upfront.

Proven Technology:
Decades of reliability in EVs and industrial applications.

Wide Temperature Range:
Performs well in extreme weather conditions, especially at low temperatures.

Ease of Recycling:
Established recycling infrastructure reduces environmental impact.
