This really is a difficult question: 
first, you'd need to tap in www.tesla.com, select country = Belgium, then Ontdekken > Laden, this opens a pop-up: 
https://www.tesla.com/nl_be/findus?bounds=51.23749123943378%2C4.064623841308577%2C51.23442470946833%2C4.054324158691389&location=28812&functionType=party

The info is: there are 20 Superchargers, capacity up to max. 250 kW , available 24/7, at Trompstraat 68 ; Tesla's dot is very much where this note was placed.
