What's the story?

Walmart has installed electric vehicle charging stations at some of its stores, only to have them ripped out and replaced with competing stations by Costco.

The move by Costco, which was first reported by Electrek, is the latest salvo in the battle between the two big box retailers over who will control the EV market.

Walmart has been rolling out charging stations at a handful of its stores, with plans to eventually have them at all its 4,750 locations.

Costco, meanwhile, has been working with Tesla to install charging stations at its stores.

The fight between the two retailers is being waged as the electric vehicle market is heating up, with more and more people looking to switch to EVs.

Why does it matter?

The Walmart-Costco fight is symptomatic of the battle that is raging between the traditional auto industry and the upstart EV industry.

The traditional automakers are struggling to catch up to Tesla and the other startups that are leading the way in EVs, and they are seeing their market share erode as a result.

As the number of people looking to switch to EVs grows, the fight over who will control the market is only going to intensify.

What's next?

It's not clear what Walmart's next move will be, but it's likely that the company will continue to try to find ways to get a foothold in the EV market.

The same is true for Costco, which is likely to continue its partnership with Tesla and try to expand its presence in the EV market.

The bottom line is that the fight over the EV market is just beginning, and it's going to be intense.
