介绍了一种用于铅酸蓄电池电解液密度测量的多点光纤传感器。众所周知，由于硫酸和水的密度不同，电池充电过程会产生分层。为了研究这一过程，应在不同深度进行密度测量。我们在本文中描述的传感器与传统传感器不同，它由多个测量点组成，允许在电池内部不同深度进行密度测量。所获得的一组测量值有助于确定电池的电量（SoC）和健康状态（SoH）。
This article describes a multi-point optical fiber-based sensor for the measurement of electrolyte density in lead-acid batteries. It is known that the battery charging process creates stratification, due to the different densities of sulphuric acid and water. In order to study this process, density measurements should be obtained at different depths. The sensor we describe in this paper, unlike traditional sensors, consists of several measurement points, allowing density measurements at different depths inside the battery. The obtained set of measurements helps in determining the charge (SoC) and state of health (SoH) of the battery.
