As @freddym , if you take the question literally then the answer is No. If the OP meant vary the charge rate to maximise the use of Solar, then all of the above and the ChargedEV and Growatt/ProjectEV one.Andersen A2 allows a solar input.
All grid connectedMany Bannatyne based Instavolt chargers have huge solar panels on the roof, at Rotherham it must be close to 50kwh. Look at Google map satellite.

Yes I mean a mains charger which is supplemented by input from solar panels (and, Ideally, a wind turbine). Electronically not very difficult or expensive to do.
Or it would be a further segmentation of an already minority product. What proportion of EV owners have the opportunity to charge from DC solar with the voltage conversion being controlled purely by the car from potentially a vast range of voltages?Sadly, it seems that such innovation is way beyond the imagination of modern car designers...
Be foolish not to be, a 50-100 kW charger with solar/wlnd sitting without a connection to the grid, how do you use the power when not charging, how do you get power when no sun nor wind?All grid connected
But there is a DC:AC conversion and voltage conversion to mains voltage that takes places between the solar panel and the charge point, and then back the other way from ACC and from mains voltage to battery voltage in the on-board charger. The OP likes the elegance of having no form change and only a single voltage change from solar to car battery. This can be done and would potentially be marginally more efficient, but if this on the car it further complicates an already expensive device, requires a new protocol to connect the solar panel to the car at hugely variable voltages (single panel ~ 30V, home array up to 600V, commercial ?), all for something that most users cannot take advantage of due to no solar where their vehicle is when it needs charging. Currently it is simpler and more cost-effective to just connect solar to the grid and either charge via AC or via Rapids accepting the greater inefficiencies in the rare event that they happen to be close together.Doesn't a charger like the Zappi effectively do this by detecting export/import... ? I haven't got one, so I'm not sure, but I'm sure someone will be along in a minute ...
