It is a significant issue to develop silicon/carbon composite anode with high-capacity and long cycling stability for lithium-ion batteries. However, the huge volume expansion of silicon during lithiation leads to severe pulverization of silicon, resulting in serious capacity fading over cycles.
Design of Energy Storage Charging Pile Equipment The main function of the control device of the energy storage charging pile is to facilitate the user to charge the electric vehicle and to charge the energy storage battery as far as possible when the electricity price is at the valley period.
The new energy storage charging pile system for EV is mainly composed of two parts: a power regulation system and a charge and discharge control system. The power regulation system is the energy transmission link between the power grid, the energy storage battery pack, and the battery pack of the EV.
The user can control the energy storage charging pile device through the mobile terminal and the Web client, and the instructions are sent to the energy storage charging pile device via the NB network. The cloud server provides services for three types of clients.
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.
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.
The data collected by the charging pile mainly include the ambient temperature and humidity, GPS information of the location of the charging pile, charging voltage and current, user information, vehicle battery information, and driving conditions . The network layer is the Internet, the mobile Internet, and the Internet of Things.

Silicon (Si) is widely used as a lithium-ion-battery anode owing to its high capacity and abundant crustal reserves. However, large volume change upon cycling and poor conductivity of Si cause rapid capacity decay and poor fast-charging capability limiting its commercial applications. Here, we propose a multilevel carbon architecture with vertical …
Additionally, the superior performance of Si was attributed to its higher reversible potential, which enabled higher overpotentials before the Li-plating onset, and its smaller thickness. Moreover, the charging rate of the Si electrodes was two times faster than that of graphite before reaching 0 V vs. Li + /Li.
