With EV exploring demand and government encouragement, EV charger market, as a rigid demand, should match EV drivers' need no matter at home or public location.

This is a EV charger market chart from Y2021 to Y2030.  We can see clearly the trend is increasing rapidly.

To keep 28% increasing every year,  EV charger manufacturers need to take super effort on EV charger part purchasing. But during these 3 years, no matter the electrical parts or mechanical parts , most parts are suffered from shortage due to the Covid and ecnomic.

How to solve this EV charger part shortage problem?

1, Design 2~3 alternative parts as cross reference. 

If this manufacturer part is not in stock, the other model or other 2 models can be backup immediately. Pls check the availablity with part manufacturers or distributor such as ABPower at first.

Especially for electrical parts as: ABB/ Eaton/ Schneider MCCB, Safety relay, Fuse, Contactor, terminal block, Fuse holder etc.

Here is some parts cross reference list we design for some EV charger manufacturers. 

The mechanical parts alternative list is not included in this sheet. 

Pls ask us if you meet any electrical parts shortage. We can give you the proper parts with inventory.

2, Keep safety stock for most key parts such as IC, Breakers,  Safety relay, Fuses, Contactors, Connectors.

Normally 2~3 months demand stock should be considered ahead of production.

Or you can find some distributors with safety stock to other EV charger customers. Since the DC fast charger performance is similar, they can share  the Part Numbers and stock.

3, Source 2~3 suppliers for your key electrical/mechanical part.

For famous part manufacturers such as Eaton, ABB, Bussmann, Schneider etc, Each distributors have unique advantage parts.  ABPower focus on electric power parts, Other distributor may focus on electronics parts.

So the leadtime, price will be different. Depends on the part type.

4, Better to use famous part manufacturers

Such as Eaton, ABB, Schneider etc, they are big group, also with numbers of distributors. It'll be easier to find the stock in market.

For small manufacturers, due to the raw material shortage problem( Such as platics shortage), Raw material companies will supply mainly to their key customers (Eaton , ABB etc) , Then other customers. Because the quantity and long term relationship.

Or small companies need to find some raw material with losing quality to support market. But from the surface you cannot find it.

5, Double check the part number if active in part manufacturer

Sometimes when it's coming to EV chargers' end, engineer find that the part number has already end of life. This will take more time to find the alternative part when in implementation stage because you will need to revaluate the part in user side. This takes longer time, cost and effort. And with effect on original plan.

If can double check on part manufacturers' website or ask their distributor, it will help a lot.

For example, electrical part manufacturer Digi, part: WR11-M600-DE1-XB, this number has been end of life when you check on official website.

There is no fix ways on part supplying, only you can find the right source. Feel free to let us know any questions on EV charger parts.
