Control Vdc working limit (Саудовская Аравия - Тендер #39725802)

I need a piece that works on 48 DC volts. Do the following when the voltage reaches 53, send a Normal open signal and continue this signal until the voltage reaches 47 DC
I will need this device, as it separates the charging from the battery when the voltage reaches 53, so that the battery discharges, and when the voltage reaches 47, it reconnects the current to charge it again. I will connect this piece to the battery charging control board
i need an electronic piece to read the voltage. Where it works to separate the electricity from the battery charger when the voltage reaches 53 or 100% charge. Then reconnect again when the battery reaches 47 volts or 40% of the charge value
I will connect this piece to the electrical circuit breaker (contactor), to will give a signal to it to disconnect or operate(No/NC),
