The active power source drives the system directly while the battery charges unloaded. MOSFETs Q1 and Q2 and diodes D1 and D2 bypass the battery and connect the active (USB or AC adapter) power input directly to the load. When a power input is valid, its monitor output (UOK or DCOK) goes low to turn on the appropriate MOSFET.

depleted 16 kWh battery pack in a PHEV to a 95% charge in about four hours from a 240 V supply [1]. There are mainly two types of charging systems, as shown in Figure 3: AC and DC charging systems. An AC charger powers the battery through the vehicle''s onboard charger, while a DC charger directly charges the vehicle''s battery.
Also known as DC or fast charging, Level 3 charging uses direct current (DC) to charge a vehicle''s battery directly, instead of the alternating current (AC) used by Level 1 and 2 charging stations. This allows Level 3 chargers to bypass an EV''s slower AC/DC onboard converter and deliver DC power directly to the battery.

The specific power of a battery is related to its specific energy and can be defined as its power per unit weight (W/kg). Yet, it specifies the amount of power a battery can provide for a given weight. In contrast to specific energy, specific power has no bearing on the maximum range an EV can travel without recharging [86].
