Most car batteries are +- 350 - 400V DC. Hybrid solar transformers supporting high volt batteries are available. In that case the dc port of the EV can be used and the transformer to limit the current. I think making the EV dc port bi-directional should not be a big technical issue. How a dc...

An AIO is an external ATS, automatic transfer switch? (I looked it up and it seems to be an All In One, normally having an internal bypass ( ATS); with or without usable dry contacts?) This info is also for connecting solar panels and it is important to warn for the possible problems if AIO are...

What earthing system do you use? such off grid inverters have an internal bypass connecting the grid to the home load if batt volt is low. the AC in port can be used for grid or gen. This means it must be avoided the internal bypass to become active if connecting V2L to the AC in port to charge...

if one has a hybrid solar inverter connected to batteries, most of them also have a GEN port. You just have to plug V2L output in the gen port and use it as it was an emergency generator. Using V2L one can not connect PE out to earth as this propably will stop de-charging. if only used for...

The advantage of having heated seats is consuming much less range for creating a comfortable environment in cold weather conditions, as is a heat pump. Both are standard equipment on all BYD Dolfin, for about the same price. The MG4 basic model has a bigger batt but this difference is not shown...

I have solar pannels and use an all in one hybrid inverter with gen port. if connecting V2L to gen port it is able to recharge the home battery or supply power the the home load. I use an AC coupled hybrid DEYE inverter with back-up but one may use an all in one in series inverter creating an...

It does, the EV must use resistance heat to warm the car and batteries if no heat pump. This drains the battery. The same EV with or without a heat ump, it makes a huge difference in range, Battery preheating for DC charging without a heatpump?

As do most other cars pulling a caravan. 1/3 at least. This is not typical EV. I go from 6l/100km to 9L/ 100km pulling 1500kg, even 10l-12l in the mountains. An Ev loads his batteries coming down. It is about the same range most European EV lose in winter because they do not have a heatpump in...

The same concerns may be made for connecting a generator. Most portable generators also are floating systems suitable only to connect one double isolated device in all safety. if such generator is connected to the home electrical installation of coarse a transfer switch must be used to avoid...

V2L is a floating system, which means there is no protection. Only double isolated electrical devices may be connencted. Such devices have no earth wire. If you connect 4 devices and there is an isolation fault in one device this may have effect on all connected devices and its users. As...

Earth wire coming from the MG? What is its normal purpose in a floating setup? This wire probably can be used to earth the MG internal inverter? Is this wire also providing an N bound if it is connected to earth? For this one should check if V2L N and PE are connected or not. I do not think this...

In Belgium all home installations are TT systems ( Terra- Terra), which means the N is not bound to earth in the home distribution box and the N bound is made at the distribution transformer of the GRID. The home installation must have effective RCB and home earth may not be connected to N . I...

In fact there is not a lot to avoid; It is about connecting one wire more or not.

Ok. but what is the problem? It is the normal setup of a TT system . In a TT system metal parts in the home should be interconnected and bounded to the home PE. In a TT home system PE earth must have a very low impedance. The N is bounded to earth at the utility transformer of the grid...

In Belgium an ATS must have a transfer time of minimal 50 ms. In an island setup everything is isolated from the utility.

if connecting the MG to an N bound distribution system is not a problem for the MG, then all PCB and CB in a TT system will work normally. What should be the risk? The bounded N of the grid can easily be replaced with a PE bounded N coming from the EV v2L connection, the same way a home battery...

if one uses an all in one solar hybrid inverter, most have an internal ATS for switching between grid mode and off grid mode ( back up mode) Some have a GEN port which can be configured. Advanced settings "Island mode". In Island mode the N is bound, when on grid it is not and the signal can be...

Some models on the front. Better for street charging but certainly no less dangerous in the event of an accident, and than the high repair costs. Insurance companies are already taking this into account. Also with the location of censors, cameras, etc... and in the end it is the buyer who pays...

normally v2L is used with a transfer switch for switching between grid or V2L. if the GRID is a TT system the N is earthed at the transformer station. One does need an earthed N for PCB to work. In TT systemsThe home installation must have a PE pin and the N is not connected to PE. The only...

Talking about normal 7 or 11 kw chargers made available in the city, those chargers logically are on the right hand side of the road using a LHD; in Belgium it is NOT allowed to park in the direction against the traffic. The charging cable must be at least 3 m longer as necessary with the...
