apis-main is the name of energy sharing software for autonomous distributed control of energy developed by Sony CSL. apis-main is installed in each node (battery system connected to the DC grid via a bidirectional DC/DC converter). Via the Device Driver, the software periodically obtains the remaining capacity of the battery and automatically carries out energy sharing between nodes by nagotiating with other apis-mains in accordance with behavior rulesets determined by each node’s remaining battery capacity. Negotiations between apis-mains use a communication line such as Ethernet, and the energy sharing takes place with direct current on the DC grid. apis-main does not rely on software that carries out centralized control of nodes. All nodes have the same software, apis-main, and autonomous distributed control is carried out with only apis-main in each node.

Refer to the apis-main_specification for more information

Here is how to install apis-main individually.
git, maven, groovy and JDK must be installed in advance.

$ git clone https://github.com/SonyCSL/apis-bom.git
$ cd apis-bom
$ mvn install
$ cd ../
$ git clone https://github.com/SonyCSL/apis-common.git
$ cd apis-common
$ mvn install
$ cd ../
$ git cone https://github.com/SonyCSL/apis-main.git
$ cd apis-main
$ mvn package

Here is how to run apis-main individually.

$ cd exe
$ bash start.sh

Here is how to stop apis-main individually.

$ cd exe
$ bash stop.sh

Set the following parameters in the exe folder as necessary.
