6 FAQs about [Power frequency inverter charging power for auxiliary battery]
What is auxiliary inverter charger (AIC)?
Auxiliary Inverter Charger (AIC) * Electric Vehicle (EV) and Plug-in Hybrid Electric Vehicle (PHEV) have been globally developed to realize sustainable world. An on board charger is required for charging at home, but it is not necessary to bring the charger while driving. The on-board-charger becomes only `weight’ while driving vehicles.
Which auxiliary inverter should be used as a charger?
Compared with a traction-motor inverter, an auxiliary inverter, which is independent from driving, braking and steering, is a good candidate as a charger. Secondary, power ratio between charger (3kW) and inverter should be in the same range.
Can a frequency converter be used to build a fast charging battery converter?
This paper proposes the use of a frequency converter used in the AC motor drives to build a fast charging battery converter for electric vehicles (EV). The possibility of using semiconductor integrated modules with two-level inverters and diode rectifiers for the construction of high power voltage DC/DC converters has been demonstrated.
Why do we need auxiliary inverter?
Smaller in volume and lighter in weight for charger is achieved with a modification of existing auxiliary inverter. No additional cooling unit such as cooling liquid pipe, air duct, fan etc. is required for charger function. And important bidirectional charging function can be easily realized easily with software control. 2.
How can a fast battery charging system be integrated with industrial power networks?
Fast battery charging systems for autonomous electric work machines should be integrated with industrial power networks in such a way as not to increase the electricity demand of the power system. This can be achieved by using additional renewable energy sources and energy storage (Marra 2013 ).
How much power does a DC/DC converter need to charge a battery?
According to Fig. 5, a DC/DC converter with a minimum power of approx. P (1C) = 282 kW should be used to charge the battery set in 1 h with 1C current or with a power of 846 kW to charge the battery in about 20 min. with 3C current.
