Market Gate and the Glassworks car park are the closest according to this. https://www.zap-map.com/live/

There's one at the ground If I'm not mistaken, don't know if it's for public use though Saying that, it might be an idea to check with Biddy he/she seems to knows the coming and goings of the car park if past threads are anything to go by lol
Need more info - depends on what you are looking for. Are you looking for a slow 'destination' charger where you can park up and graze for a few hours while at the match? If so, best options would be the 6 Mer units in the Glassworks car park or the 6 Blink units in the Mark Street car park up past Morrisons. There are also 4 Mer units in the Sackville St car park and 6 in the Churchfields car park. Never used any of them so can't vouch for any of them - just looked on ZapMap. Or are you looking for a rapid charger to top up quickly? If so, not sure why that would need to be close to the ground as you surely wouldn't leave it on a rapid and come back hours later? It might as well be somewhere on the route and the best place would be somewhere there are lots of them. Best option close to town is the 12 x E.on units at the Fairway, but its out of town and not close to the ground at all. In town, the main one are 2 MFG units at Morrisons and 2 Instavolt units at McDonalds. If heading north to Barnsley, there are the 8 Applegreen units at both Rotherham services or Woodall services (southbound on the way back home). If heading south to Barnsley, there are 13 Gridserves at Woolley Edge, both northbound and Southbound. Plenty of options.
Double check though...Zapmap shows two charging points near me....one doesn't exist and the other is for Council vehicles only.
