电池支持
SHA-1
验证。验证将在机器人和电池之间严格进行。
The battery support SHA-1 Authentication. Authentication will strictly between robot and the
battery.
11. 电池固件要求 Battery Firmware Requirements
电池有电池管理系统
(BMS)
来控制和保护电池，同时实现与主机通讯。
BMS
有以下功能。
The battery have a Battery Management System (BMS) to monitor and protect the battery and
to communicate to the robot. The BMS has following functions.
充电控制
Monitors Charging
监测电池充电，通过测量充电电流计算容量，能识别满充。
Monitors battery charging & accumulates battery capacity during charging from
measurement of current. Detects full charge.
放电控制
Monitors Discharging
监测电池放电，通过测量放电电流计算容量，当电池不充电时，BMU能补偿
电池的自放电以及自身功耗。
Monitors battery discharge & accumulates battery capacity from measurement of
current. When battery is not charging, BMU compensates for battery's self
discharge and its own consumption current.
