Because car manufacturers don't make components. Have a look on the tyres of your Volvo. They won't say "Volvo". I saw a switch on an Audi with the VW, Seat, Audi and Vauxhall logos. I mentioned the Aisin gearbox on my Jaguar. I had a Rover 75 with a BMW engine. My wife's Mini has an engine from a Toyota Yaris and my daughter had a Nissan with a Renault engine. Those were all from the factory like that.
The brake light bulbs, the battery and the tyre valves on my 2009 Jag are interchangeable with those on my 1953 MG. Car manufacturers don't change stuff unless they have a good reason to change. If there is engineering work done, it's to save money, add or improve features, improve styling, or keep up with changes in law. In many cases you can see the effect of a gradual change in the design of cars. For instance, a Diesel injector pump for common-rail injectors, where the timing is electronic, but the pump ran at exactly the same speed as the camshaft, not because it had to, but because the previous injector pump had to run at that speed, and there was no saving in changing the pulley sizes or the run of the timing belt.
A quick search found this:- https://www.varaosahaku.fi/fi-en/Se...r/Battery-cable/All/ID-31298768/OEM-31327698/ which says it's made by Hella. Hella sell to all the big car manufacturers.
There is just no reason to chop and change connectors. If Volvo did that, they would pay Hella loads of money to re-tool the connector housing. The BMS won't work on another car because the software won't be compatible so they won't loose out on sales of parts if the connectors fit other cars.
I guessed that a modern Ford is probably going to have a BMS if a modern Volvo has one, and there are more Fords than Volvos so more to search for. Ford and Volvo were even part of the same group at one time. I just did an image search for Ford BMS connector or something like that.
