Global energy storage product development trend and energy storage circuit board demand analysis

Global energy storage product development trend

The global energy storage market is growing rapidly, mainly driven by the development of renewable energy, 

grid stability needs and energy security strategies. At present, energy storage technologies are mainly divided 

into electrochemical energy storage (lithium batteries, sodium-ion batteries, etc.), mechanical energy storage 

(pumped storage, flywheel energy storage), thermal energy storage and hydrogen energy storage. Among them, 

lithium battery energy storage occupies a dominant position, and sodium-ion batteries are gradually

 industrialized due to their resource advantages and low-cost characteristics.

At the policy level, European and American countries, China and other countries have introduced incentive

 policies to promote the growth of the energy storage market. Especially in terms of grid-side energy storage,

 industrial and commercial energy storage and household energy storage, global demand continues to expand, 

and the market size is expected to maintain an annual growth rate of more than 30% in the next five years.

Analysis of energy storage circuit board demand

The core components of the energy storage system include battery modules, BMS (battery management system),

 PCS (power conversion system) and EMS (energy management system), and circuit boards play a key role in

 these modules.

BMS circuit board: used to monitor battery status, manage charging and discharging, and prevent overcharging, 

over-discharging and overheating. The demand for high-precision, high-stability, and high-voltage PCBs is rising, 

mainly using **high TG boards (FR4, ceramic substrates)** and multilayer boards.

PCS control circuit board: PCS is the core of the energy storage system, responsible for the conversion of AC and

DC. The power control circuit board requires high reliability and high-voltage resistance. Multilayer boards

 (4-8 layers) are mostly used, and some high-power demand products use metal substrates.

EMS control circuit board: EMS optimizes the operation of the energy storage system through intelligent 

algorithms, mainly involving microcontroller units (MCUs), communication modules (Wi-Fi, 4G/5G), etc., 

and the demand is mainly for high-density interconnect (HDI) boards.

The demand for photovoltaic energy storage integrated machine PCB is growing: With the development 

of integrated photovoltaic storage and charging, the demand for PCB boards that support high-power 

conversion and intelligent control is increasing, such as PCBs with high voltage resistance and high heat 

dissipation performance.

Overall, the market demand for energy storage circuit boards will expand rapidly with the growth of the 

energy storage industry, and the future technical direction will focus on high power, high reliability, intelligence 

and other fields.
