Wide-scale adoption and projected growth of electric vehicles (EVs) necessitate research and development of power electronic converters to achieve high power, low-cost, and reliable charging solutions for the EV battery. This paper presents a comprehensive review of EV off-board chargers that consist of ac-dc and dc-dc power …
This article proposes a single-stage inductive-power-transfer (IPT) converter operating as a wireless constant-power (CP) and maximum-efficiency battery charger. By maintaining a constant output power rather than providing a constant output current throughout the dominant stage of battery charging, the IPT converter can make the utmost of its power …

9.6: Electrical Energy and Power
2.1. Numerical descriptions for power demand The power flow within the battery during vehicle operation is characterized as bi-directional, contingent upon the charging or discharging modes. This phenomenon is mathematically represented by the following equation [30]: (1) P bat = (1-K) P bat, c h + K P bat, d i s where P bat, c h and P …
Example 2.5.1 Example 2.5.2 Efficiency Example 2.5.3 Example 2.5.4 The terms power and energy are often used incorrectly as synonyms. Although related, they are not the same thing. As already mentioned, energy is the ability to do work. In contrast, power is ...
