The development of the 12 v battery -Power Kingdom

Battery manufacturers to provide battery design life for the specific conditions of the theoretical value, not equal to the actual service life. Actual service life and the conditions of use ( Environment temperature, discharge depth, power frequency, battery management, etc. ) Closely related, and the design life there is a difference, even far. Domestic access network supporting the development of the 12 v battery, the matching 12 v battery access network are mostly built into the main equipment rack bottom, daily access network maintenance sometimes ignore the check of the battery. Think in terms of battery maintenance, the following factors need attention when battery matching: 1, the battery performance in the use of the environment is not ideal, traffic location is remote area, equipment reliability, Quality performance) As a key consideration, second price factors ( Within the scope of reasonable battery performance and low cost) ; 2, 2 v battery selection access network based on the actual application requirements, in accordance with YD/T799-2002 standard, formulate corresponding battery type specification; 3, main and auxiliary equipment bundles ( Integration) Supporting way because of the characteristic of the access network is scattered construction, engineering installation, maintenance workload is bigger, plus some devices will be built-in battery, in general, supporting the preferred method for main and auxiliary equipment integration; 4, optimize the distribution of the 12 v battery from overseas turnkey engineering battery configuration design, the design capacity & other; Split & throughout; Is the mainstream trend, it can improve power system security. Such as 48 v 200 a & middot; H, using two groups of 48 v 100 a & middot; H in parallel, 1 200 a group of 48 v & middot; H higher reliability.
