Why new energy vehicles still need lead-acid batteries?

With the advancement of technology and environmental protection, automobiles are gradually transforming from fuel engine to electric engine. In the future, new energy vehicles will gradually be popularized. Battery will take the place of fuel to become mainstream power source. At present, there are more and more types of batteries developed in the market, but does the lead-acid battery still have a place in the market as a "veteran leader"?

The answer is yes.

12V power supply system

There are many electrical appliances on traditional fuel vehicles that use 12V voltage. (For example: Central locking, interior lighting, wipers, lights, on-board computer, etc.) The application of these electrical components has been continuously optimized in the development of decades, and the functions have gradually become stable and reliable. Today, a large number of new vehicles are still assembled with these components every year around the world.

New energy vehicles are also equipped with a 12V electrical system as standard. Since re-development of electrical components for a new voltage system will generate a lot of extra costs, no car company is willing to re-develop. Therefore, such application scenarios will not have big changes at a period of time in the future.

Due to the characteristics of stability, easy availability and low risk of lead-acid batteries, most of the 12V electrical systems of new energy vehicles also use lead-acid batteries for power supply.

Redundant power supply for safety requirements

The 12V battery on the new energy vehicle can also be used as a redundant power supply, providing redundant power for safety functions. For example, power-assisted steering function provided after the engine of a hybrid vehicle is stopped. Of course, it is not just new energy vehicles that use electronic power steering systems today.

In addition, the 12V battery can also supply power to the driver assistant system, For example, the more popular function of the automatic cruise system, which not only focuses on safety issues, but also focuses on the improvement of driving comfort and economic efficiency.

awake high voltage lithium battery system

Before the high-voltage lithium battery system enters the working mode, the safety detection must be performed by the control unit, and the power required by the control unit is provided by the 12V battery. Therefore, if the 12V battery is in an excessively insufficient voltage state, the high-voltage lithium battery will not be able to be awakened, and eventually, the vehicle will not be able to start.
                                

Security Status Change

The new energy vehicle from "high pressure system off" state to "vehicle stationary" state also requires a second energy source to ensure basic safety functions such as wipers, lights, brakes, steering, etc. When the vehicle is running at full speed, if it encounters in an emergency, the high-voltage system needs to be turned off instantaneously, and then the low-voltage system needs to be able to keep the door lock, sound, navigation system, etc., continue to work when the high-voltage system is turned off.

After reading so much, do you feel that although there are many new types of new energy, the lead-acid battery still occupies their market! Therefore, lead-acid batteries will still occupy a relatively high market share in the battery industry, and are widely used in fields such as automobiles, communications, power batteries and energy storage.

In recent years, with the development of China battery industry and the dominance of national policies, the industrial concentration of lead-acid batteries in China has reached a relatively high level. Better Technology Group Limited, as a rare "High-quality export operation platform for  battery industry" in China, it integrates general contracting system integration services such as R&D design, project planning, complete sets of equipment, installation and commissioning, technical output, technical training, and after-sales support. BETTER is committed to providing global customers with turnkey solutions for battery manufacturing full resource operations and complete sets of equipment (including equipment, batteries, raw materials, auxiliary materials, related accessories, battery production technology output and other related businesses), using stable and efficient Chinese battery manufacturing technology capabilities to lead customers' battery projects to rapidly increase production and expand. Which completely solves the problems of long project construction period, heavy technical docking tasks, unreasonable production line matching, and cumbersome business communication caused by customers purchasing from multiple places.
