TIDM-02002 reference design | TI
CLLLC resonant DAB with bidirectional power flow capability and soft switching characteristics is an ideal candidate for Hybrid Electric Vehicle/Electric Vehicle (HEV/EV) on-board chargers and energy storage applications. This design illustrates control of this power topology using a C2000™ MCU in closed voltage and closed current-loop mode.
Power Topologies in Electric Vehicle Charging Stations
1.2 DC Charging Station. The DC charging station is a Level 3 charger which can cater for very high power level in the range of 120 to 240 kW. The L3 chargers typically charge batteries to 80% State of Charge (SOC) in under 30 minutes. To achieve such high power levels modular converters which can be stacked are used.
Designing ultra-rapid DC EV chargers
A DC EV charger will typically take a mains AC feed of between 100 and 400 V and after some noise filtering, pass the current through a full-wave rectifier and a smoothing filter to drive a DC-DC converter. The DC-DC stage steps the low-line voltage from the AC supply up, to the high-line voltage the vehicle requires.

EV charging infrastructure design resources | TI
Build fast, efficient EV charging solutions with leading high-voltage power, current and voltage sensing and connectivity products and designs. EV charging needs to be quick, affordable, safe and reliable. Providing a flexible infrastructure to generate, store, transmit and distribute the additional power is crucial for the electrification journey.
Designing DC fast chargers for next-gen EVs
A DC Fast Charger (Figure 2) can charge an EV battery to 80% capacity in under 15 minutes. These chargers have power ratings up to 350 kW and can supply up to 500 A to a battery. To develop these chargers, designers must overcome the challenges of safety, efficiency, and reliability. Figure 2.
Sensata Precharge Circuit for Hybrid and Electric Vehicules
The precharge circuit usually consists of a separate, smaller contactor connected in series with a resistor. These two components are then wired in parallel across the main contactor (Figure 2). The precharge circuit is commonly found on the positive leg, but it could just as easily be installed on the negative leg.

Your questions answered: How to design electric vehicle charging ...
Electrical engineers designing EV supply equipment (EVSE) and systems to incorporate and support EV charging must be aware of the basics of charging as well as how the customer plans to use the charging stations. From this, the electrical engineer must be well versed in not only the EV charging hardware (Level 1 and Level 2 AC chargers, …
Basics of battery charging circuit design
Unless a Li-ion battery is charged very slowly (usually 0.15 C or even less), terminating the charge based on reaching a voltage of 4.2 V/cell will only charge the battery to a maximum of 0.7C. Some batteries may only reach 0.4C. Charging Li batteries at less than 4.2 V/cell is possible but also not recommended.
