Electrical car charging is available in numerous styles and sizes. Gradual, quick and fast chargers. Kind 1 and Kind 2 connectors. Chargers at residence, the office and in public – there are quite a few great methods to energy your electrical automobile.
Nonetheless, there’s one essential EV element that performs a pivotal position within the performance of electrical car charging – the onboard charger (OBC).
However what’s an electrical automobile onboard charger?
We’re right here to offer all of the solutions. On this weblog, we are going to clarify what an electrical automobile onboard charger is, how onboard chargers for EVs work, and supply most onboard charger charges for a few of the hottest electrical car chargers.
What’s an onboard charger for an electrical car?
An electrical car (EV) onboard charger (OBC) is a necessary a part of each electrical car. Since electrical automobile batteries solely cost with Direct Present (DC), an electrical automobile onboard charger’s principal duty is changing Alternating Present (AC) from the electrical energy grid into Direct Present (DC) so as to cost your electrical automobile.
Essential – Ensure you don’t get EV onboard chargers mistaken for an precise electrical automobile charging level that you just plug in – whereas they work collectively, they’re separate.
Since all residence electrical car chargers use alternating present (AC) – vitality from the grid is all the time AC –, and since EV batteries can solely cost with direct present (DC), your EV makes use of its onboard charger to transform vitality each time you plug in to cost.
The place is an electrical automobile onboard charger situated?
The onboard charger is situated throughout the electrical car itself, typically built-in into the powertrain or close to the battery pack. Its main job is to handle and management the charging course of, making certain secure and environment friendly conversion and supply of direct present to the EV battery.
How does an EV onboard charger work?
When an EV is plugged into an AC charging station (three-pin plug chargers, residence EV chargers, or sure public charging factors), the onboard charger throughout the EV communicates with the electrical automobile charging station to find out the out there energy, voltage, and charging capability. It then converts AC into DC energy earlier than regulating the circulate of electrical energy into the battery, efficiently charging your electrical automobile.
There are various kinds of onboard EV chargers out there, relying on the car’s make and mannequin. To not point out how every EV’s onboard battery charger has a most AC charging restrict – which means that even when you charged over your most onboard charging fee, your EV received’t cost any faster.
How do I do know what dimension kW onboard charger my electrical automobile has?
Electrical automobiles come outfitted with onboard chargers that decide their most AC charging fee, typically measured in kW (kilowatts). To seek out the precise most onboard charging fee to your electrical car (EV), check with your EV’s guide.
On the entire, the out there most charging charges for electrical automobiles vary between 3.7kW and 22kW. Nonetheless, the commonest most onboard charging fee for a lot of electrical automobiles is round 7kW – particularly 7kW, 7.2kW or 7.4kW. This 7kW commonplace charging fee is prevalent amongst EVs and is also known as quick charging, making it a preferred selection for residence chargers.
Some electrical automobiles, notably premium fashions, supply even larger onboard charging charges, reminiscent of 11kW and 22kW. It’s important to notice that no electrical automobile presently exceeds a most AC onboard charger of 22kW. In fact, in case your EV can cost at charges of 22kW, your charging time will likely be faster than 7kW chargers.
Smaller electrical automobiles typically have most charging charges of round 6kW or 7kW, with slight variations like 6.6kW, 7.2kW, or 7.4kW. Alternatively, extra premium electrical autos have a tendency to offer the next most charging fee, averaging round 11kW.
As an illustration, Tesla autos are famend for his or her larger most charging charges:
Tesla Mannequin 3 onboard charger – 11kW
Tesla Mannequin S onboard charger – 11kW
Tesla Mannequin Y onboard charger – 11kW
Don’t get your most AC onboard charging fee confused along with your DC charging fee. Since batteries cost with DC, you should use high-power DC fast cost factors of as much as 150 kW to cost your EV if you wish to – most charging charges are just for AC.

Are there every other variations of an onboard charger?
Sure, two-way onboard chargers are of their infancy. A two-way onboard charger converts AC from the grid to DC throughout the EV whereas additionally permitting DC to be transformed again to AC when it’s offered to the grid. In different names, this two-way onboard charger is named ‘Automobile to Grid’.
As we talked about, ‘Automobile to Grid’ expertise just isn’t a widespread follow within the UK, however with future developments, it’s more likely to develop into extra well-known within the subsequent decade.
Do plug-in hybrids electrical automobiles have onboard chargers?
Sure, plug-in hybrid electrical automobiles have onboard chargers. Nonetheless, since hybrid electrical automobiles have each an inner combustion engine (just like petrol and diesel autos) and an electrical motor, the onboard charging fee is considerably decrease – sometimes between 3.3kW-3.6 kW.
What’s an offboard charger?
In contrast to an onboard charger, an offboard charger is outdoors of your electrical car and is situated within the EV charger that you just’re utilizing, not the car itself. The distinction between onboard and offboard chargers is that an offboard charger converts AC from the grid to DC earlier than feeding the electrical energy again to your battery.
EV charging factors with offboard chargers are often fast or ultra-rapid public EV charging factors. For the reason that EV onboard charger isn’t wanted, DC fast chargers permit for quicker charging classes with larger charges because it feeds DC vitality straight to your electrical automobile’s battery, bypassing the necessity for conversion.
Abstract:
– An electrical car onboard charger (OBC) is an important element accountable for changing alternating present (AC) from the grid to direct present (DC) to cost an electrical automobile.
