基于大容量电芯的摄像机电池 Camera battery based on large capacity battery
技术领域 Technical field
本发明涉及一种摄像机电池， 尤其是一种采用两节大容量电芯串联组成 的电池， 具体地说是一种避免了多节电芯串、 并联导致电池 "短板效应" 的 基于大容量电芯的摄像机电池。 背景技术 The invention relates to a camera battery, in particular to a battery comprising two large-capacity batteries connected in series, in particular to a large-capacity based on avoiding a multi-section battery string and parallel connection causing a battery "short board effect" Battery camera battery. Background technique
随着摄像机的广泛应用，摄像机用电池也逐渐得到人们的重视，体积小、 容量大、 重量轻成为人们在选择摄像机电池时考虑的重要方面。 为了满足用 户对大容量电池的需求， 目前业界普遍采用的方法是采用多个 （如 6个或 8 个）体积较小容量较小的小电芯并联之后串联，但这种方法存在的问题就是， 电芯数量过多从而导致电池整体体积增大，给用户使用带来不便； 除此之外， 这种方法存在的另一个问题就是当多节电芯串联、 并联使用时， 性能最差的 电芯往往成为整个电池组的瓶颈， 由于"短板效应"， 性能最差的电芯通常早 于其他电芯充满， 也早于其他电芯放空， 在反复的充放电循环之中， 这种差 距会逐渐扩大， 持续使用 6个月以后， 差距会更加明显， 最终将造成整组电 池性能的提前劣化， 从而影响整体电池的使用寿命。 如何在摄像机电池的体 积和容量之间做好平衡， 在体积最小化的同时实现容量的最大化， 是目前摄 像机电池急需解决的一个问题。 With the wide application of cameras, the battery for cameras has gradually gained people's attention. The small size, large capacity and light weight have become important aspects for people to consider when selecting camera batteries. In order to meet the user's demand for large-capacity batteries, the current method commonly used in the industry is to use multiple (such as 6 or 8) smaller cells with smaller capacity and parallel connection, but the problem with this method is Excessive number of cells leads to an increase in the overall volume of the battery, which is inconvenient for the user; in addition, another problem with this method is that when the multi-cells are connected in series and in parallel, the worst performance is obtained. The battery core often becomes the bottleneck of the entire battery pack. Due to the "short board effect", the battery with the worst performance is usually filled earlier than other batteries, and is earlier than other batteries, in the repeated charge and discharge cycle. The gap will gradually expand. After 6 months of continuous use, the gap will become more obvious, which will eventually lead to the deterioration of the performance of the entire battery, which will affect the overall battery life. How to balance the volume and capacity of the camera battery and maximize the capacity while minimizing the volume is an urgent problem to be solved in the current camera battery.
此外， 现在市场上一般的电池只能专用于摄像机的供电， 摄像机用的拍 摄灯则需要另外的电源供电， 这也不便于用户的拍摄使用。 发明内容 In addition, the general battery on the market can only be used exclusively for the power supply of the camera, and the camera light for the camera requires an additional power supply, which is not convenient for the user to use.
