What is the difference between an inverter and DC/DC converter in an electric vehicle?

Much like how internal combustion engines and alternators work together on conventional vehicles, hybrid cars and electric motors use inverters and converters to manage power to and from the battery pack to the motors and other on-board systems.

Inverters transform direct current (DC) from the battery into alternating current (AC) to power the vehicle. Inverters also control the motor and convert it to a generator, transferring braking energy back into the battery.

Converters control the DC voltage from the battery, either stepping it up or down based on the system and the power needed. DC/DC converters usually step down the high voltage from the battery pack to the 12-volts used by radios, headlights, and more.

An OE solution for aftermarket power electronics

Inverters and converters work together to manage the vehicle's electric drive and accessory systems. However, many of today’s inverters and converters can be complex, expensive, and prone to failure from excessive heat. They are also heavy and take up a lot of room on the vehicle, compromising both trunk and passenger compartment space. Delphi OE solution combines the inverter and DC/DC converter into one unit.

Delphi CIDD is cost-effective and saves vital weight and space in hybrids (HEV), plug-in hybrid electric (PHEV), and electric vehicles (EV). And by leveraging patented OE technology - Viper-enabled inverter’s double-sided cooling - it tackles the issue of overheating, allowing higher power outputs from a smaller package and increased range.

Combined Inverter and DC/DC Converter (CIDD)

Enhances durability and reliability through features designed to withstand under the hood and environmental factors such as debris and temperature extremes.
Improves voltage distribution functionality, enabling both low-side and high-side power for everything from headlights to power steering and air conditioning systems.
Provides maximum packaging flexibility and space savings by moving the DC/DC unit from its standard location in the rear to the front of the vehicle.
Enables better power range and minimizing power losses through the elimination of cabling, cooling hoses, connections, and housings, all while simplifying maintenance and repair.

Resource Highlights

Our Delphi Technologies Expert highlights the differences between approved and non-approved EV chargers. Let us show you how to safely charge an electric vehicle.

Can I use an EVSE lead to charge my vehicle each time?

An EVSE lead is great for charging your vehicle when you’re out and about, but it isn’t ideal for permanent use. Don’t forget, an EVSE lead will be limited to 10-13 amps depending on your country. For most EV’s that is only 6-9 miles per hour of charge.

Can EV chargers cause an electrical socket to overheat?

Approved EVSE chargers have an in-built temperature sensor installed in the plug, so if it gets too hot, the charger will switch itself off. A non-approved charger may not have this feature and can cause heat damage to the electrical socket.

How can I tell if the EVSE cable is charging the vehicle or not?

The ‘Power’ light will be on to tell you that the EVSE lead is receiving power. Below it, the ‘Charging’ light will flash to tell you that the vehicle is being charged.

What does the ‘Temperature’ light mean on the EVSE charger?

If that light is on, it means that the EVSE lead is getting too hot. Switch it off and allow it to cool down.

What is wrong when the ‘Fault’ light comes on?

On the back of the EVSR lead, there is a handy list of all the faults that could have caused the light to flash. Check each one to narrow down the cause of it.

Can I use the EVSE lead with an extension cable?

This is not advised – it must be plugged directly into an electrical socket. Never use an extension lead without uncoiling it first.

Why isn’t the vehicle charging when I’ve connected it to an EVSE lead?

There are a number of reasons why this can occur and can vary from vehicle to vehicle. For example, on some models, the vehicle needs to be locked for it to begin charging. The customer may also have set a specific charging schedule that is programmed into the car, which will only allow for it to charge at a certain time. It’s best to check the vehicle’s handbook for guidance before charging.
