The battery?Fuel cells?All you need to know is right here

Alliance between giants

Batteries and fuel cells are not in competition; on the contrary, a combination of the two can provide a variety of power-matching schemes.At present, pure electric technology is more widely known, such as electric excavators, electric buses and so on.But a combination of battery and fuel cell technologies could reduce carbon emissions more effectively and improve energy efficiency while ensuring performance.

Fuel cells can improve battery performance, especially in terms of range and refueling time.This has opened up new possibilities in some applications where pure electric vehicles were not available in the past.Regardless of how the engine and power source are configured, the battery system is always a key component of the electric power solution. It will not be replaced by the fuel cell, but will play a greater role in combination with it. Cummins has a variety of power solutions, we will use professional skills and 100 years of experience to meet the needs of users, from the mileage, weight, attendance, performance and other aspects of consideration, for users to customize their required power solutions.

Both batteries and fuel cells can be used as power sources, but in different ways.The purpose of the battery is to store energy and transfer it to the powertrain.Fuel cells, on the other hand, use hydrogen as a fuel to generate electricity.Because hydrogen itself ACTS like a battery, acting as an energy carrier and storage device.

At this stage, however, fuel cells have limited ability to dynamically provide energy to the powertrain, unlike batteries that can respond quickly to load demand.But fuel cells offer improvements to conventional electric vehicles, including improvements in performance and endurance.Moreover, fuel cells have the potential to use renewable energy on a large scale and accelerate the application of sustainable energy.

In terms of application, the biggest difference between batteries and fuel cells is the applicability of medium and heavy transport.

For pure electric vehicles, the maximum axle load allowed would limit the number of battery packs, as well as road limits and net cargo capacity considerations.As a result, Cummins is committed to making our battery powertrain lighter and more efficient.In general, long distances and high loads require more volume and weight, while larger and heavier batteries can lead to reduced performance and efficiency.For example, the route of urban express transport vehicles is relatively short and parking is frequent. Traditional pure electric vehicles can well meet this demand.

Fuel cell electric vehicles have higher energy density and longer range, making them more suitable for long-distance and high-load transportation scenarios.Hydrogen tanks are also more compact and lighter than fully charged batteries;In addition, hydrogen supplementation is cheaper than battery charging.

In terms of operation, there are differences in attendance and usage between battery and fuel cell vehicles.

A fuel cell car can be fully charged in a matter of minutes, allowing it to have a higher attendance rate than other alternative energy solutions and almost comparable to conventional internal combustion engine vehicles.However, traditional pure electric vehicles are generally more suitable for the use mode with convenient charging. For example, the daily driving route of vehicles is relatively fixed, the starting point and the ending point are at the same place, and there are fixed charging stations.

Infrastructure costs are also an important consideration when choosing a power plan.Megawatt power charging solutions not only reduce charging time from hours to minutes, but also reduce the amount of on-board battery storage required to perform tasks.Real-time or dynamic wireless charging may also help reduce the need for storage of on-board batteries.In this way, electric cars can be charged while running.

In fact, the two technologies are neck and neck, with only one option more suited to the user’s needs.Battery solutions can effectively serve the transportation field, but when their application is limited, fuel cell technology can be used.

Cummins, backed by hundreds of years of technology and experience, offers users the choice of these two technologies.Electric power is the future of transportation, and Cummins will lead the way with a diverse range of power solutions.
