In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
On the one hand, the energy storage charging pile interacts with the battery management system through the CAN bus to manage the whole process of charging.
Reversible heat is generated at cathode and anode. It is entropic heat originates from reversible entropy change during the electrochemical reaction. It increases as charging rates increases from 1C to 2C and then it decreases at 3C during charging and discharging . This heat may be endothermic or exothermic type.
Many factors, including the battery temperature, energy density, and charge/discharge rate, impact the heat generation rate. At moderate and high charge rates, the total heat generation is typically positive and drives the battery to a higher temperature.
The charging pile determines whether the power supply interface is fully connected with the charging pile by detecting the voltage of the detection point. Multisim software was used to build an EV charging model, and the process of output and detection of control guidance signal were simulated and verified.
