By definition, the guard terminal is nearly at the same potential as the high impedance terminal, so the guard terminal will be at the same potential as the magnitude of the voltage source.
根据定义，保护端与该高阻端处在几乎相同的电位，所以保护端就与电压源为相同电位。

Based on environment temperature and battery terminalvoltage, the controller can also adopt proper charge mode, such as overcharge and floating charge, to extend the battery life.
Varies the generator terminalvoltage in accordance with its load to hold constant voltage at some point electrically remote from the generator, such as the station high voltage bus.
