ELECTRICITY SUPPLY SYSTEM |
摘要 |
An electricity supply system is provided. The electricity supply system comprises: a battery module (1), comprising at least two in-series modules (11), each in-series module (11) comprising at least two battery groups connected in series; a control module (2) connected with the battery module (1), comprising: an IGBT module (23), a relay module (22) comprising a plurality of relays K, in which each in-series module (11) is connected to the relay module (22), and the relay module (22) is connected to the IGBT module (23), a relay control module (21) configured for controlling an ON or OFF of each relay K so as to select one or more in-series modules (11 ) to work with the IGBT module (23); and a distribution box (3) connected with the control module (2). The electricity supply system may realize heating battery groups in batches and equilibrium of voltage between battery groups. |
