If you’ve ever seen an electric or hybrid vehicle on the road, or owned one yourself, you can say you’ve witnessed the transformation of the transportation industry toward electrification. But another revolution you may not see is how cars manage battery charging and power usage, how they connect and make mobility smarter and safer through the use of artificial intelligence and machine learning, and those that will redefine how we use safely and innovative technologies for maintaining car
Electrification of transportation is the future, and in many ways already a reality, let’s take a closer look at the key innovations behind this transformation.
The electrified future is already taking shape
In the past, there may have been people who questioned the global electrification transition, but the impressive growth in electric vehicle sales last year was enough to dispel any doubts.
Global sales of electric vehicles (EVs) will reach 6.75 million units in 2021, a 108% increase from 2020, including passenger cars, light trucks and light commercial vehicles. All of the world’s leading carmakers have already started selling or plan to launch electric models, and some will soon sell only electric cars in individual markets. ) will launch a series of pure electric vehicles. Ford, Sony, and Honda have also announced new plans, and automakers have been rolling out new models and plans for electric vehicles that are almost dizzying.
While the transition to vehicle electrification begins with a shift to batteries to power vehicles, true electrification is much more than just using batteries to replace gas tanks. This means that the battery can provide the car with enough power to carry passengers and cargo to its destination, continue driving when the battery is charged, and create a charging infrastructure that functions like a gas station. It is also important to ensure that all electric vehicles on the road have a reliable and accessible network connection, while also protecting user data and privacy. The realization of the above aspects is inseparable from the functional safety and network security of the car. At the same time, it is necessary to integrate the latest AI and machine learning innovations to realize the functions of assisted driving and automatic driving.
NXP is always on the ground to drive every step of the electrification revolution, helping to realize an electrified future sooner rather than later.
Batteries are just the starting point
While batteries are not the end of the electrification revolution, there is no doubt that batteries are the starting point for this revolution. As a power source, the battery is directly related to the mileage and function of the car, which in turn affects the acceptance and satisfaction of users. Car batteries are completely different from the batteries we use every day, such as those in TV remotes and other devices, and they can be replaced with new ones when they are depleted.
Electric vehicle batteries are quite complex, and intelligent machines and semiconductors play an important role in how the batteries work. The better the battery is managed, the further an electric car can travel on a single charge. For example, a battery management system (BMS) includes integrated circuits (ICs) and sensors that control key characteristics such as voltage, temperature, and current to maximize the battery’s power output while balancing the battery’s functions to ensure its safe operation.
16 of the world’s top 20 automakers have adopted NXP solutions in their battery system designs.
Lower energy consumption and longer mileage
Once the battery reaches peak efficiency, the next step is to convert the electrical energy into torque to turn the wheels and run all the in-vehicle technology (from the entertainment system to opening and closing the windows). The car itself is a very complex technological system, using electricity to drive hundreds of sensors and functions, and electric vehicles are even more technically demanding. This means that to enhance the driving experience, distributing and using electricity is as important as generating it.
The all-electric Audi e-tron uses NXP’s battery management system and is powered by NXP’s MC33771, MC33664, FS45 and FS65 power chips
NXP provides automakers with the framework to build the next generation of electric and hybrid vehicles, the “Power Control Reference Platform.” The platform integrates NXP’s power inverters (which convert high-voltage battery power into the current needed to drive traction motors), our world-class microcontrollers, power management SoCs and gate driver chips, which can be combined with other The components of the vehicle system are connected. Nine of the top 20 electric vehicle OEMs have adopted the reference platform in their inverter projects.
Convenient, safe and fast charging
Only when team members understand their own value, tolerate, recognize and respect each other, can we increase our sense of identity and enhance our innovation ability and profits. Everyone is a winner.
Like any machine that consumes energy, electric vehicles need to be recharged, which means providing drivers with easy and fast charging facilities, whether public or private. Achieving this is not just about increasing the number of sockets or simply plugging and unplugging, but also ensuring the safety and reliability of power measurement and payment transactions during charging.
Grid operators need real-time and reliable power consumption data to effectively manage power loads. Likewise, energy providers need customer IDs, accurate energy consumption records, and up-to-date pricing and billing information in order to create and send billing orders. Additionally, charging installation operators need to record and analyze performance data in order to manage and maintain their facilities. Finally, electric vehicle charging pile manufacturers need to monitor the operation of the equipment and manage the maintenance and update of software and hardware.
Such connectivity could also support innovations such as adjusting electricity prices on demand, encouraging off-peak charging, and even allowing car owners to sell excess energy stored in batteries back to the grid for emergency needs. It also makes it easier for car owners to use the car and increases their satisfaction.
When it comes to safety, electric vehicles can be thought of as a collection of IoT devices on wheels, in other words, they are able to connect with other vehicles, surrounding infrastructure, and data in the cloud to obtain real-time driving and entertainment information, access and complete Machine learning tasks to improve their functionality (stationary charging stations can also be connected in a similar way). However, it could also leave a “back door” for hackers, making the cybersecurity of electric vehicles as important as driving and charging performance.
At CES in January, NXP and its partners demonstrated a solution that gives users remote access to battery and power management, allowing automakers to improve vehicle performance and support smart car.
During the charging process, the safety and reliability of power measurement and payment transactions must be guaranteed.
The road to 2030 will change our lives
In the next few years, you will see continued growth in the number of electric cars or own an electric car yourself. According to estimates by research institutes, the number of electric vehicles will increase tenfold within a decade (from 10 million to 100 million or more by 2030). Not only will these vehicles reduce carbon emissions over their lifetime, but their corresponding increase in demand for renewable energy will further reduce greenhouse gas emissions.
