Embodiment Construction

[0032] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the implementation device for communication cascading of multiple sets of lithium battery packs provided by the embodiment of the present invention includes: a host, more than one slave, and a host computer; the host is electrically connected to each of the slaves, and the The host is also electrically connected to the upper machine; the host and each of the slaves includes: a battery pack containing a protection board and an isolated communication circuit electrically connected to the battery pack containing a protection board. Wherein, the isolated communication circuit is an isolated communication circuit with an electromagnetic isolation chip, and its model may be an RS485 isolated communication circuit. Since the isolated communication circuit realizes that the internal power supply of the isolated communication circ

Abstract

The invention provides a device and method for realizing a communication cascade of multiple lithium battery groups. The device comprises a host machine, an upper machine and more than one slave machines. The host machine is electrically connected with each of the salve machines respectively. The host machine is also electrically connected with the upper machine. The host machine and each of the slave machines comprise a battery group which is provided with a protective plate, and an isolation communication circuit which is electrically connected with the battery group having the protective plate. Therefore, a use state of each battery group can be effectively monitored so that a situation of an overcharge or an over-discharge of each battery group can be avoided, and a use safety of the whole battery group system is enhanced.
