Battery technology has not yet broken through to the next technology cycle. In this era of battery life, power management chips may become the best choice for feasibility at this stage. As the popularity of smart electric vehicles increases, they will play an increasingly critical role.
Current status of electric vehicle batteries in winter
In winter, the internal combustion engine can generate heat by itself, which can make the engine and the interior of the car warm at any time. However, electric vehicles must first use their own electricity to create heat, which will also consume cruising range, which also means that the cruising range is even shorter.
In any situation where the batteries in electric vehicles are lower than 5 degrees Celsius or higher than 50 degrees Celsius, they will not exert their best performance. As the temperature drops, the internal efficiency of the battery cells will slow down, and the discharge will not reach the desired level. The power is even more limited when charging.
According to the test of electric vehicles by the American Society of Automobile Engineers, the average reduction ratio of the cruising range in winter can reach 41%; in urban conditions, after the wind heating is started in winter, the cruising range will be further reduced by an average of 20%-30%.
Power management chips further penetrate into the automotive field
Power management chips are mainly used in fields such as computers, communication equipment, automobiles, and industrial control. In recent years, the power management chip application field has shown a gradual transition from low-end consumer electronics to high-end industrial and automotive fields.
According to the forecast of ICInsights, the power management market is expected to achieve an increase of more than 8% last year, which will become one of the main driving forces for the growth of analog chips in the next five years.
①With the continuous upgrading of semiconductor process technology, the chips and components on the PCB board have higher functions, faster operation speed, and smaller size, which drive power management to provide lower and more accurate nuclear power voltages and larger power supply currents. Strict voltage feedback accuracy and higher efficiency performance.
③The application field of power management continues to expand and deepen. It is indispensable to achieve better control functions, smarter control loops, faster dynamic response characteristics, and more simplified peripheral layout design.
③Although the largest terminal market for power management chips is still mobile phones and consumer Electronic products, since these products are relatively low-end, price competition is fierce.
④In the automotive and industrial power supply IC market applications, due to its high application technology requirements and high product gross profit margins, most foreign manufacturers focus on the automotive and industrial power supply fields with higher thresholds.
On the whole, the transition from the low-end consumer electronics market to the high-end industrial and automotive markets in the application of power management chips in the future will become a new trend in the development of the industry.
The intelligentization of energy products is the general trend
The use conditions of power products for industrial equipment are relatively harsh, and some applications require 24 hours and 365 days of uninterrupted operation. Therefore, when designing and developing power products, the requirements for power devices are very high, and two technical considerations must be taken:
①Due to the demand for uninterrupted operation, how to reduce the loss caused by the device has a direct impact on the factory’s electricity bill. And different applications require different switching frequencies. According to the actual switching frequency requirements, it is determined whether the conduction loss or the switching loss is the priority, and then the best choice is determined.
②In an unmanned factory, device failure will directly affect the operation of the factory and cause losses, so the tolerance of the device also needs to be considered first. The intelligence of power supply products can help solve these problems, but the power devices used in power products are relatively large, usually multiple chips are used in parallel, so Renesas Electronics believes that it is not the intelligence of a single chip, but a complete set of equipment The intelligentization of the company is bound to be the general trend.
The global power management chip industry enters the first year of integration
Electronic product technology upgrades are still in progress, such as fast charging technology, electric vehicles, 5G, etc., still have upgrade requirements for power management chips, and this will also become a key area for manufacturers to compete at the moment.
Renesas (Renesas) acquired Intersil;
ADI acquired Linear, Apple and Dialog reached a $600 million deal. Dialog will authorize its power management technology, transfer some assets, and send 300 R&D engineers to Apple.
From the perspective of the global market, the growth rate of power management chips is not very fast, but it grows every year. It belongs to a relatively stable market, and emerging markets have not yet seen scale effects.
Electric vehicles are the main driving force of power management chips
With the follow-up of my country’s new energy vehicle supporting industry and the continuous construction of charging piles and other factors, we predict that my country’s new energy vehicle market will continue to grow in the next few years, which will also drive the rapid development of the upstream power management market.
The power management chip is a chip that is responsible for the conversion, distribution, detection and other power management responsibilities of electric energy in the Electronic equipment system. The chip converts the power from one form to another form efficiently and stably, such as alternating current Convert to direct current, convert low voltage input to high voltage output.
Power management chips exist in almost all electronic products and devices, and are widely used. Power management chips are mainly used in fields such as computers, network communications, consumer electronics and industrial control. In addition, although the automotive electronics field has a relatively small market share, it has developed rapidly in recent years.
It is precisely because of the wide range of applications that power management chip shipments rank first among all types of chips. According to ICInsights data, in terms of shipment volume, it is estimated that four of the top five IC categories are analog devices. And the total number of analog devices will account for 55% of the total number of 301.7 billion ICs expected to be shipped in 2019. Power management analog devices are expected to account for 21% of the total IC, and shipments are expected to be 63.969 billion, which is expected to exceed the combined shipments of the second and third-ranked categories.
According to YOLE’s data, the communications market occupies the most important power management chip market, and the upcoming large-scale layout of 5G will further increase the demand for power management chips in the communications field. At the same time, automotive electrification and industry 4.0 upgrades will also become a booster for power management chips.
In the future, power grids, automotive electronics, industrial control, and LED lighting will continue to grow, and PMU, DCDC, and ACDC will have better growth space. In terms of power management technology, higher integration, higher power density, stronger withstand voltage, current withstand capability, and higher energy efficiency have always been the development direction of power management chips. The continuous update and development of technology is also Will be one of the main factors driving the development of the power management chip market.
