Abstract

Zbog potrebe za većom korisnošću i duljim životnim vijekom baterija koristi se sustav upravljanja baterijama. To posebice vrijedi za litij ionske baterije, koje zbog svoje osjetljivosti na prepunjavanje i pretjerano pražnjenje zahtijevaju strogi nadzor u svrhu produživanja životnog vijeka.
Sustav upravljanja zasnovan je na ideji punjenja svih ćelija istovremeno dok se jedna od ćelija ne napuni na maksimalni dozvoljeni napon, a onda se prelazi na pojedinačno punjenje ćelija.
Kao dio tog sustava, zadatak je bio izraditi relejnu pločicu koja omogućuje da mikrokontroler upravlja punjenjem ćelija strujom do maksimalno 30 A. Pločica također služi i za mjerenje napona na ćelijama.
U ovom radu su navedene komponente koje se nalaze na pločici uz obrazloženje zašto su one stavljene na pločicu. Također, dokumentiran je postupak izrade same pločice.

Abstract (english)

Battery management system is used because of the need for greater and longer cycle life of the batteries. This is especially true for lithium ion batteries , which because of its sensitivity to overcharging and over-discharge require strict control in order to prolong the life of the battery .
The management system is based on the idea of charging the battery until one cell is filled to the maximum permitted voltage, and then switches to charging cells separately .
As part of that system, the task was to circuit relay board that allows microcontroller manages charging cells with current that is up to 30A. The board also serves to measure the voltage on the cells.
In this document, components that are on the board are listed and explained. There is documented process of making PCB, too.
