Keeping pace with high power terminal block demand

Keeping pace with high power terminal block demand

High power terminal block demand is soaring with the buildout of EV charging infrastructure. The reason is simple – high current requires high power terminal blocks, making these components essential for EV charging stations.

The rapid growth in the adoption of electric vehicles is fuelling demand for high power terminal blocks beyond what most people expected.

The UK Government’s decision to ban petrol and diesel cars from 2030 has accelerated the buildout of EV chargers, leading to significant new investment by leading companies like Tesla and BP Chargemaster. There are now more than 35,000 charge points across the UK, a figure that is expected to increase by 10,000 in 2021.

The big barrier to purchase with electric vehicles is a lack of charging infrastructure and slow charge times. Building more charging stations is the simple solution to this problem, but bigger, better high power terminal blocks are also needed for the next generation of rapid chargers that will provide power up to 350 kW.

What is ‘high power’?

Anything above 40 amps is classed as high power. All public electric charging stations significantly exceed this amount. High power terminal blocks are typically available up to 125 amps and higher for custom applications.

We need terminal blocks capable of handling higher currents when the charging speed demand increases for the station. EV chargers are classified in three categories: Level 1, Level 2 and direct current. Whether a charger is AC or DC, the higher the current, the higher the power draw, so the more robust the terminal needs to be.

Terminal block specifications

Terminal blocks serve as a routing tool for wiring. They are simple components, used to connect circuits together and provide an electrical ground for the circuit.

Screw terminal, push button and push-in terminal block styles are available. These accommodate different types of circuit design. The module type can be interlocking or single-piece with a plug or receptacle housing.

Terminal blocks for EV charging stations are optimised for this specific purpose and they are normally rated for at least 150% of the max current.

Meeting the soaring demand for high power terminal blocks

Unlike semiconductors, there is no immediate shortage of high power terminal blocks. They are available in the tens of thousands per order.

There is competition between the EV and renewable energy industry for high power terminal blocks though. Both industries are significant consumers of these components and demand is increasing with new electrical installations.

Other in-demand components for electric vehicle charging infrastructure include battery connectors and high voltage connectors designed to handle the heat of EV charging. These connections need to be small but also thermally efficient.

MLCC supply is beginning to tighten?

Memory suppliers to benefit from strong demand and supplier shortages

Multilayer ceramic capacitors (MLCCs) are used in many electronics from smartphone screens to laser guidance systems. There was a prolonged lull in demand for MLCCs stretching from 2019 through to 2020, however supply is now tightening and lead times for new components are extending.

This has caused some concern with those who use MLCCs to manufacture products. Will supply continue to tighten? When will it let up? These are good questions. The answer lies in understanding why supply is tightening.

Demand for MLCCs is tightening for several reasons:

  • Demand from the automotive sector is increasing
  • Demand from the communications and transport sectors is increasing
  • Global inventories are depleting
  • Supply chain challenges due to the coronavirus pandemic
  • Manufacturing bottlenecks due to facilities running at maximum capacity
Increased demand

The main reason for supply tightening is an increased demand from the communications and transport sectors. These sectors consume over half of the world’s MLCC supply and the rollout of 5G is accelerating demand.

The global automotive market is also a big consumer of MLCCs. MLCCs are being used extensively in modern cars. Applications include in battery management, chargers, heater controllers and energy converters. Electric cars use MLCCs because they are reliable and can be surface mounted directly to boards.

Inventory depletion

Inventory management has been a difficult task what with 2020 throwing COVID-19 into the works. This hit the MLCC supply chain like a train. Demand dropped off. This led to suppliers correcting inventory levels and sometimes overcorrecting. When demand increased towards the back end of 2020, supply chains got exposed.

It is difficult to correct inventory when not enough MLCCs are being made. For every 10 that are made 8 get put into use immediately. This leaves little fat left.

Increasing lead times

All of this means increased lead times for MLCCs. Many electronic components suppliers and distributors have them on back order. Some types of MLCC have lead times extending over several months (a long time in a supply chain).

For example, large case (≥ 0603) low-CV commercial grade MLCC lead times are around 22 weeks. This is a very long time. The only units that are in good supply are small case size (≤ 0402) low-CV commercial grade MLCCs which are available now.

How can you meet demand?

As 2021 gets underway, we predict that MLCC supply will tighten. Inventories will get stretched and manufacturers will struggle to get a hold of the components they need. Now that you know this, you can prepare.

The best way to assure a healthy MLCC supply is to work with a global distribution partner like us. When you need to source hard to find electronic components quickly because of allocation, long lead times, obsolescence, or quality issues, Lantek is here to help.
