battery

battery词义丰富，如a battalion is a unit composed of a headquarters and two to six batteries [炮兵连]，可不是说一个营带2到6节电池。battery的词源是法语baterie (to hit). 伏达发明电堆时可能被电给打了不知道几下。伽伐尼用刀尖碰蛙腿上外露的神经时，蛙腿剧烈地痉挛。

In baseball, the term battery refers collectively to the pitcher [投手] and the catcher, who may also be called batterymen or batterymates of one another.

Battery is a criminal offense involving unlawful physical contact, distinct from assault which is the act of creating apprehension [忧虑;担心;恐惧] of such contact.

In military organizations, an artillery battery is a unit of artillery, mortars, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships. A main battery is the primary weapon or group of weapons around which a warship is designed. 在军事组织中，炮兵连是由火炮、迫击炮、火箭炮、多管火箭炮发射器、地对地导弹、弹道导弹、巡航导弹等组成的单元，其组合旨在促进更好的战场通信和指挥控制，以及为其组成的炮兵及其系统提供dispersion。这个词在海军中也用来描述军舰上的炮组。Dispersion is the spreading of people or things over a wide area.

A battery is a device consisting of one or more electrochemical cells with external connections for powering electrical devices such as flashlights, mobile phones, and electric cars. When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode. 电池是一种由一个或多个电化学电池组成的装置，这些电池具有外部连接，用于为手电筒、移动电话和电动汽车等电气设备供电。当电池供电时，其正极为阴极，负极为阳极。

anode的词根也是a，和ashore, atop等类似。cathode: from which an electric current leaves a piece of equipment，词源是Greek kathodos 'way down'. 即：a是“到”的意思，cath是“离开”的意思。node是节点；catalyst(催化剂)里的cat可能也是way(方式)的意思。电流的方向和电子"流动"的方向相反，现在依然有"载流子"的说法。a这个词根

The usage of "battery" to describe a group of electrical devices dates to Benjamin Franklin, who in 1748 described multiple Leyden jars [莱顿瓶] by analogy to a battery of cannon (Benjamin Franklin borrowed the term "battery" from the military, which refers to weapons functioning together).Italian physicist Alessandro Volta built and described the first electrochemical battery, the voltaic pile, in 1800.

3LR12 (4.5-volt), D, C, AA, AAA, AAAA, A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 batteries

18650, 又名168A或1865, 直径18mm, 长65mm，1500~3500mAH (毫安时). This cell type is used in many laptop computer batteries, cordless power tools, certain electric cars, electric kick scooters, most e-bikes (bicycles driven or supported by electric motors), electronic cigarettes, and LED flashlights. Nominal voltage is 3.7 V. 3.7V * 3500mAH = 12.95 VAH = 13 WH. 1度电 = 1000 WH.

46800，又名4680, 直径46mm, 长80mm，其它数据不详。Introduced by Tesla in 2020 as a high energy capacity cell for use in EVs.

BYD Auto Co., Ltd. (Build Your Dreams) is the automotive subsidiary of the Chinese multinational BYD Co Ltd, which is based in Xi'an, Shaanxi Province. It was founded in January 2003, following BYD Company's acquisition of Tsinchuan Automobile Company in 2002. The company produces automobiles, buses, electric bicycles, forklifts, rechargeable batteries and trucks. The current model range of automobiles includes electric vehicles, plug-in hybrids and petrol-engined vehicles. The Denza brand, a joint venture with Daimler AG, produces luxury electric cars.

A plug-in hybrid electric vehicle (PHEV) is a vehicle that uses battery-powered electricity and gasoline in tandem for power.

BYD continued as the world's top selling plug-in car manufacturer in 2016 with over 100,000 units sold, up 64% from 2015. BYD sold more than 100,000 new energy passenger cars in China in 2016. The BYD Tang was the top selling plug-in car in China in 2016 with 31,405 units delivered.

BYD achieves top rankings of 2015 J.D Power's Quality Study. The J.D. Power U.S. Initial Quality StudySM (IQS) serves as the industry benchmark for new vehicle quality measured at 90 days of ownership.

In May 2020, BYD announced that it would start expanding in Europe, with Norway first. BYD's launch will consist of the Tang SUV and a range of commercial vehicles. BYD will deliver a total of 1,002 electric buses to Bogota, the capital city of Colombia, by mid-2022,[34] after bagging a contract of 406 electric buses in January 2021.
