A 3.5-kW hardware prototype of the proposed converter is built and tested and key experimental results are presented to verify the converter’s theoretical analysis and ZVS operation. This article proposes an integrated on-board charger (IOBC) for electric vehicles (EVs) based on an isolated three-port dc–dc converter.
In the context of electric vehicles (EVs), it signifies the resistance between the HV lines and the vehicle chassis (DC+ to chassis and DC- to chassis). What does it Mean by Isolation Monitoring? Isolation monitoring is a systematic approach to continuously assess the isolation resistance in an EV’s HV system.
In addition, low-voltage controllers must stay isolated from the high-voltage power transistors they control while also measuring the currents or voltages in other high-voltage sections of the system. Systems outside the EV, such as electric charging piles, have similar system requirements and needs for isolation.
To maintain the voltage balance of battery packs, a combined buck-boost and switched capacitor converter based on equalizers is used . Lithium-ion batteries suffer energy and power loss in cold conditions. A regular operation of an Electric Vehicle involves heating. AC heating systems are unsuitable for use in electric vehicle applications.
Charging architecture is classified in the single-way and two-way power flow direction into an on-board and off-board charger. The interconnection problem in unidirectional charging may restrict the hardware requirement, but the two-way charge supports battery energy storage back to the grid .
It involves monitoring (or measuring) the electrical resistance between the HV lines and the vehicle chassis (DC+ to chassis and DC- to chassis) to ensure that it remains within the safe limits. The circuit or device which is used for isolation monitoring is commonly referred Isolation Monitoring Device (IMD). Why is Isolation Monitoring Necessary?
