The Development Of New Energy Has Given Rise To The Application Of Integrated Busbars

Busbars are key components for electrical connections. Traditional busbars are difficult to meet the development trend of high frequency and high power of power devices due to their large parasitic inductance. Laminated busbars are multi-layer composite structures composed of conductive materials such as copper and aluminum and insulating materials, which can minimize the stray inductance of the line and ensure the normal operation of the power module. With the development of power devices, laminated busbars are widely used in rail transportation, new energy vehicles, new energy power generation, industrial automation and other fields.

The development of new energy has brought about an incremental demand for busbars and has given rise to the rise and development of laminated busbars

I. New energy vehicles: the demand for electronic control busbars has increased, and the application of battery laminated busbars has risen rapidly

Power battery Laminated Copper BusBar: Busbars are usually required in battery packs to complete the series and parallel connection of battery packs, and to collect signals such as battery cell voltage and temperature in real time. In the early days, power batteries used a wiring harness busbar solution. When the wiring harness was connected to the battery pack, each wiring harness could only reach one electrode, and multiple wiring harnesses were required to be used together, occupying a large battery pack space and with a low degree of automation. With the increasing requirements for integration and lightweight of battery packs, laminated busbars have gradually emerged and been widely used. Battery laminated busbars combine aluminum bars, signal acquisition components (FPC, FFC, etc.), insulation materials, etc. through hot pressing or riveting. They have the advantages of light structure and high integration, which can improve the efficiency of battery pack assembly and space utilization. They currently dominate the application of Power Battery Busbars.

Electric control busbar: The motor controller is the core of the motor drive and control system. The electric control busbar is integrated with the DC bus support capacitor of the motor controller to achieve the connection of high-voltage lines inside and outside the motor controller. The electric control busbar is designed by lamination and pressing, which can effectively reduce inductance and reduce the risk of equipment damage caused by high voltage breakdown.

II. Energy storage: The penetration rate of battery laminated busbars is expected to continue to increase

Energy storage battery laminated busbar: Similar to the power battery of new energy vehicles, energy storage batteries also need busbars to realize the series and parallel connection of battery packs and collect signals such as voltage and temperature. At present, energy storage batteries still use more traditional wiring harness products, and Laminated BusBars solutions are gradually replacing them. We believe that with the improvement of energy storage battery sampling requirements and the degree of integration, the penetration rate of laminated busbar busbars in energy storage battery applications is expected to continue to increase.

III. Wind and solar power generation: driving the increase in demand for industrial electrical busbars
Benefiting from the increase in wind and solar power generation installed capacity, the demand for laminated busbars suitable for high-power scenarios has steadily increased. In recent years, the scale of new energy power generation has grown rapidly. Power conversion modules such as photovoltaic inverters and wind power converters require busbars to achieve electrical connection between power devices and main circuit components. The operating voltage range of the busbars of photovoltaic inverters and wind power converters is 1000-1500V. Therefore, the demand for industrial electrical busbars suitable for high-power application scenarios has steadily increased. Industrial electrical busbars need to be customized according to specific electrical performance parameters, spatial structure, etc. At the same time, they have high requirements for voltage resistance, inductance, and insulation performance, and have high reliability and safety.
