A power conversion system including a triple active bridge (TAB) is provided. The system includes a power factor correction (PFC) module and a three port converter (TPC) module, with no post-regulation or additional stages required. The TPC module includes an OBC full-bridge and an APM full-bridge, each being inductively coupled to the output of the PFC full-bridge, thereby forming the TAB. The OBC full-bridge is adapted to convert an AC input into a high-voltage DC output for a high-voltage battery, and the APM full-bridge is adapted to convert an AC input into a low-voltage DC output for a low-voltage battery. The power conversion system can accept a single-phase AC input and a three-phase AC input, has a lower current stress as compared to prior art TPCs, and freely transfers power from among any ports.

A charging and discharging apparatus includes a communication module and a conversion module. The communication module is communicatively connected to a BMS and is configured to, in response to the apparatus being in a first energy transmission mode and the BMS not supporting a specific discharging protocol, perform first communication with the BMS based on a universal charging protocol. One side of the conversion module is connected to a battery and another side of the conversion module is connected to an alternating current side connecting structure. The conversion module is configured to convert direct current provided by the battery into alternating current and transmit the alternating current to the alternating current side connecting structure during the first communication. The first energy transmission mode is a mode in which the battery transmits power to the alternating current side connecting structure of the apparatus.

A power source system mounted in a vehicle includes: a first power source (2); a first load (41) operated by electric power supplied from the first power source (2); a first controller (9) that controls an operation of the first load (41) by a first program; a second power source (8) connected to the first power source (2) via a converter (7); a second load (11) operated by electric power supplied from the second power source (8); a second controller (10) that controls an operation of the second load (11) by a second program; an electric power disconnecting device (3) that connects or disconnects between the first power source (2) and the first load (41); and a third controller (12) that controls the electric power disconnecting device (3). When the first program is changed, the third controller (12) disconnects the first power source (2) from the first load (41) by the electric power disconnecting device (3) before a change process of the first program is started.

An apparatus structured to control an electric vehicle accessory of an electric vehicle during a charge event includes a controller communicatively coupled to a battery and an electric vehicle accessory. The controller is structured to determine that the battery of an electric vehicle is undergoing a charge event, and based on determining that the battery of the electric vehicle is undergoing the charge event, place the electric vehicle accessory in an on-state during the charge event, and cause the electric vehicle accessory to recharge by absorbing energy from the charging station during the charge event.
