Taking charge of electric vehicles – both in the vehicle and on the grid
A plug-in hybrid electric vehicle (PHEV) requires a power electronic system between the power grid and the high-voltage battery pack located inside the vehicle. This electronic system is split into two parts: a charging station, which is also called electric vehicle service equipment (EVSE) or an off-board charger, and an onboard charger inside the vehicle.
Four Key Design Considerations When Adding Energy Storage to Solar Power Grids
Solar energy is abundantly available during daylight hours, but the demand for electrical energy at that time is low. This balancing act between supply and demand will lead to the rapid integration of energy storage systems with solar installation systems.
Maximising power for Level 3 EV charging stations
With increasing battery capacity and decreasing battery cost, electric vehicles (EVs) are becoming more commonplace. Just as traditional internal combustion engine (ICE) automobiles spawned the need for more gas stations, EVs will also drive the demand for more public charging options.
Comparing Shunt- and Hall-Based Isolated CurrentSensing Solutions in HEV/EV
The global market for electric vehicles (EVs) and hybrid electric vehicles (HEVs) is rapidly growing as these vehicles offer higher fuel-efficiency and lower emissions compared to gasoline or diesel vehicles and use power from renewable energy sources. To control energy flow and optimize efficiency in HEV/EV powertrain subsystems such as traction inverters, on-board chargers (OBCs), DC/DC converters, and battery management systems (BMS), precise and accurate current measurement is essential. These high-voltage subsystems must measure large currents at high voltages, typically >400 V. Thus, these current measurements require isolation as well as high performance in harsh automotive environments.
Overview of power conversion topologies for EV DC chargers training
In DC EV Charging systems, there are two main building blocks; AC/DC and isolated DC/DC power conversion. To support V2G or V2H, these topologies must operate bi-directionally in the future. In addition, and, to solve the challenge of optimising size and efficiency, it’s important to consider moving from two-level topologies to multi-level topologies as well.
TIDA-01606
This verified reference design provides an overview on how to implement a three-level three-phase SiC based DC:AC T-type inverter stage.
