The heart of every electric vehicle is the high-voltage traction battery that powers the motor. But with so many options on the market, choosing the right one can be difficult. According to Extrapolate, the traction battery market is expected to reach $2.6 billion by 2028.
In this blog, we discuss everything you need to know about traction batteries. From understanding the science behind them to exploring the different types including lead acid, nickel-metal hydride, zebra batteries, and used batteries. We also cover charging systems for traction batteries and tips for efficient charging. Let’s take a closer look at it.
What is a traction battery and how does it work?
Traction batteries are a type of battery used to power electric vehicles. It works by storing and releasing electrical energy to power the vehicle’s motor. Traction batteries are typically rechargeable and provide the power your vehicle needs to operate efficiently and sustainably.
Traction batteries, used to power electric vehicles and a variety of traction equipment, are rechargeable and specifically designed for high energy density deep discharge. This battery stores the energy needed for electric traction, allowing the vehicle to move. They are widely used in electric vehicles, forklifts, golf carts and other electric vehicles, and play an important role in ensuring efficient operation. The amount of energy these batteries can store is critical to their usefulness in EV applications.
The Science Behind Traction Batteries
Traction batteries efficiently store chemical energy and convert it into electrical energy to power electric motors for traction. These batteries are designed for long life and utilize regenerative braking to recharge during deceleration. This essential component for electric vehicles plays a critical role in the automotive supply chain by providing the energy needed for propulsion. The projected market revenue for battery electric vehicles is expected to reach $681.2 billion by 2028.
Additionally, a battery charger is required to recharge the battery when it is 80% discharged, making it critical to the efficient operation of an electric vehicle. The science of traction batteries involves the composition of active materials and the design of thicker plates to handle circulating charges.
Different types of traction batteries
Lead-acid batteries, commonly used in electric vehicles, offer reliability and economy. Secondary batteries used in electric vehicles, such as nickel-cadmium batteries and nickel-hydrogen batteries, have high energy density and long lifespan, making them suitable for various EV applications. Utilizing nickel sodium chloride chemistry, Zebra batteries offer high specific energy and long life, making them ideal for certain electric vehicle applications. Each type of traction battery, including lead-acid, nickel-cadmium, nickel-metal hydride, and others, has unique advantages and limitations suited to different applications depending on specific energy, weight, voltage, and energy efficiency requirements.
1. Lead acid battery
Lead-acid traction batteries, commonly used in electric vehicles, offer reliability, high charging speeds, and fast charging capabilities. Despite their low energy density, they can deliver high currents, making them ideal for certain applications. These batteries are low maintenance and suitable for short driving ranges.
However, their relatively high environmental impact requires proper disposal and recycling. Recharging – With a sufficient power supply, good battery life is typically achieved at charging rates of less than half the battery capacity per hour (“0.5C”). Therefore, a full charge will take more than 2 hours. Large capacity battery.
2. Nickel hydride battery
Nickel-metal hydride batteries, also known as NiMH batteries, have higher energy density, longer range and extremely long life than lead acid batteries. With their long life, low maintenance costs and low environmental impact, NiMH batteries are ideal for hybrid vehicles, appliances and electric vehicles. These lightweight batteries are ideal for applications requiring higher voltages. Thanks to their energy efficiency, Nimh batteries are widely used in electric vehicles and outperform lead-acid batteries in a variety of EV applications.
3. Zebra Battery
Powered by nickel chloride chemistry, Zebra batteries offer high energy density and long life. Fast charging capabilities, high charging rates and low operating temperatures make them ideal for applications requiring specific energy, weight ratio and energy efficiency. Long-life Zebra batteries are environmentally friendly and serve as an alternative to traditional traction battery technology. This makes it particularly suitable for electric vehicle applications, making it a promising option for the future of EV batteries.
traction battery charging system
Proper charging of your traction battery is essential for its longevity and performance. The right charging system maintains battery capacity, voltage, and energy efficiency, preventing overcharging or overcharging. An efficient charging system contributes to a vehicle’s overall energy efficiency, improving performance. Choosing the right charging system can optimize your traction battery to achieve a full charge and deliver the amount of energy needed for a variety of applications, including EVs and recreational vehicles.

Considering vehicle type and specifications
Each vehicle has unique battery specifications and energy requirements. The weight ratio, energy storage capacity and power of the battery are affected by the vehicle type. Each vehicle type requires a specific traction battery pack based on weight ratio and energy efficiency. It’s important to consider your vehicle type and specifications when choosing the right traction battery to ensure optimal performance and compatibility.
Final takeaway
When choosing a car battery, it is important to understand the different types available and their pros and cons. Lead-acid batteries are cost-effective but have limited capacity, while nickel-metal hydride batteries have higher energy density but are more expensive. Zebra batteries are known for their high temperature tolerance, but they are not suitable for all vehicles. Lithium-ion batteries, on the other hand, are lightweight, energy-dense, and are considered the future of electric vehicles. When choosing the right traction battery for you, choose the battery that best suits your vehicle type, specifications, and desired performance. Ultimately, the decision comes down to balancing factors such as cost, performance, and environmental impact.
