IHMO- as soon as the battery were installed backwards- most of the electronics in the car would be fried ( electronics want to see a negative ground!). So- I don't think therese's anything wrong with the EV the problem is probably with the charger. If you have a multimeter- you can check the polarity of the charger Black Negative- Red Positive. I just looked up the charger and it looks like an all-right device- so just measure everything.

Thank you for your response. Would a battery installed in reverse operate perfectly fine for months and then not work? Would it be able to be jump started?

A few months ago I replaced the alternator and battery in my 2001 EVC.
Today I had to jump start my van. I used a TACKLIFE jump starter and
connected the jump starter black connector to the negative post and the
red connector to the positive post. I was immediately able to start the
van. However the jump starter indicated that I had reversed the clamps
(but I hadn¡¯t). I find this a little disconcerting. Any ideas why this
might have happened.
Could it be that your battery is connected backwards?
It is possible (though definitely bad practice!) to connect a lead-acid
battery backwards. The alternator will charge it backwards, and actually
reverse its polarity! The plus terminal becomes minus, and the minus
becomes plus.
The battery still (barely) works, but has very low capacity and short life.
