That website is wrong. It is giving you the conjugations for the verb répartir (to divide), not repartir (to restart).
You can see the correct conjugations in any good online dictionary. (Here’s a link to the correct page on WordReference.)
To answer your question, repart is present tense and should not have an accent. The core root of this particular verb is “repar-” and that will not change no matter the verb tense; only the ending will vary.
