Description

根据路线计算电量的方法和电池管理***  Method for calculating electric quantity according to route and battery management system 技术领域Technical field
本发明属于电动车领域，提供了一种根据路线计算电量的方法以及电池管理***。  The invention belongs to the field of electric vehicles, and provides a method for calculating electric quantity according to a route and a battery management system.
背景技术Background technique
电池容量是指电池存储电量的大小。电池容量的单位是'mAh'，中文名称是毫安时（在衡量大容量电池如铅蓄电池 时，为了方便起见，一般用'Ah'来表示，中文名是安时，1Ah=1000mAh）。若电池的额定容量是1300mAh，即130mA的电流给电池放电，那么该电池可以持续工作10小时（1300mAh/130mA=10h）；如果放电电流为1300mA，那供电时间就只有1小时左右（实际工作时间因电池的实际容量的个别差异而有一些差别）。这是理想状态下的分析，数码设备实际工作时的电流不可能始终恒定在某一数值（以数码相机为例，工作电流会因为LCD显示屏、闪光灯等部件的开启或关闭而发生较大的变化），因而电池能对某个设备的供电时间只能是个大约值，而这个值也只有通过实际操作经验来估计。 Battery capacity refers to the amount of battery storage. The unit of battery capacity is 'mAh', and the Chinese name is mAh (measured in large-capacity batteries such as lead batteries) For the sake of convenience, it is generally indicated by 'Ah', the Chinese name is Anshi, 1Ah=1000mAh). If the rated capacity of the battery is 1300mAh, that is, the current of 130mA discharges the battery, the battery can work for 10 hours (1300mAh/130mA=10h); if the discharge current is 1300mA, the power supply time is only about 1 hour (actual working time) There are some differences due to individual differences in the actual capacity of the battery). This is an analysis under ideal conditions. The current of a digital device can not always be constant at a certain value. (In the case of a digital camera, the operating current will be large due to the opening or closing of components such as the LCD display and flash. Change), so the battery can only provide a certain value for the power supply time of a device, and this value can only be estimated through practical experience.

Whether the power is enough, many times when you walk halfway, you find that the power is not enough. When you are in a dilemma, the user can only push the electric car to the nearest charging station to charge before starting, which will waste a lot of time and cause the user A lot of trouble.

Requires power, prompts the user to use the battery, avoids the situation that the electric car is not enough, and helps the user to better plan the route.
