About this deal

One of the most important safety mechanisms to include is a ground current detection system. The chassis of the car is grounded via the earth wire through the charging plug. The earth supply comes from the consumer unit (we have TN-C-S supply). AC-1: imperceptible, AC-2: perceptible but no muscle reaction, AC-3: muscle contraction with reversible effects, AC-4: possible irreversible effects, AC-4.1: up to 5% probability of ventricular fibrillation, AC-4.2: 5–50% probability of fibrillation, AC-4.3: over 50% probability of fibrillation So we need to measure current flowing to ground (should be zero in normal operation). If this is more than 20 mA we want to isolate the car by opening the relays. The reason RCDs typically trip at 5-30mA is because this amount of current for a couple hundred milliseconds doesn’t cause permanent injury to humans. I like the wikipedia article on electrical injury.

We also created the same chart of 7.2 kW charging time for the top 10 selling EVs in Europe because the popular cars are different. Instead of the Audi and Porsche in the US, smaller and more efficient cars made the car for the European Top 10, perhaps speaking to government support of efficient or social consciousness. Manufacturer Level 3/DC Fast Charging: This is the fastest form of charging currently available, typically found at dedicated public charging stations. Not all EVs can use this level of charging, and even those that can may require special adapters. Unsafe to use an Arduino (ATMEGA328P). I think you technically need special authorisation from atmel to use this chip for automotive or safety critical applications. I like the suggestion of incorporating a watchdog timer to guard against hanging. I’ll add that. And I like the suggestion [steaky] of having to regularly toggle a pin purposefully to maintain engagement of the relay so they’d open by default during an error. Is that actually done in commercial chargers? It’s not done by the EVSE. If an unexpected reset occurred the relays would open in this implementation. A Level 1 charger, the slowest charger, will take much longer to charge a 7.2 kWh battery than a Level 2 or Level 3 charger. Finally, the 7.2 kW charging time to a specific range or mileage will vary depending on the efficiency of your electric vehicle.An LM358 Op-Amp takes a 0-5V PWM signal from the Arduino and converts it into a +/-12V signal to form the pilot. Easy. Here at EV King, delivery is free for all items so this shouldn’t affect your decision. One consideration is that a longer charging cable is more expensive, but that is purely down to the additional materials that are in the cabling, more expenditure on materials and manufacturing the higher the cost.

The SWA cable enters the Zappi enclosure through an outdoor water resistant gland. The live and neutral pass together through a current transformer before attaching to the PCB. Ground Current Detection

Should be a type B RCD – I think this is the main point from everyone. That the RCD functionality is inadequate. I essentially copied the EVSE RCD design, which I thought was a acceptable approach. What do people think of the EVSE RCD? The requirement for EV chargers to have a Type B RCDs is a relatively new regulation brought into play in the last few years. This forum discusses the change prior to the standard being introduced. Type B RCDs can detect DC ground fault currents (not such an easy thing to do), this is a good article explaining how everything about them and how they work. They're far less common than AC ground faults! Level 1: This is typically the charging level achieved with a standard household outlet. It’s the slowest form of charging. Sometimes, your car might charge slowly. Try pre-heating the battery before charging and see if this helps. Your charger might also be balancing the power demand. Although they do have a couple of downsides, they also have some advantages! As you might be aware ev charging cables are often stolen, a tethered ev cable has a permanent connection which makes it much more difficult. There is also no risk of misplacing your charging cable as it is fixed to your charging station but in the same breath, there is often another reason why people need a new charging cable. As people are so used to diesel and petrol cars, electric car owners often forget that car is connected to the charge point and drives off, using a tethered solution means that this will cause more damage as both the cable and the charging station will both of been damaged. Type 2 cables have resistors that communicate with the car and tell it that the cable is plugged in and to keep charging whilst other resistor functions are maintaining the uniform supply of power as it detects the strength of the cable and derives power accordingly. Whereas the resistors in the Type 1 cable detect whether the cable is plugged in the car or not and decide to turn off the charger in case the lever is pressed to unlatch the plug.

In simple terms, you are advised to buy a tethered ev cable if you are looking to permanently connect your cable to a charging station. This brings a couple of disadvantages, imagine in 5 years’ time when the vast majority of households will have a charging station, you will not be able to carry your cable round to your friend’s house to charge your vehicle nor will you be able to connect your vehicle to a public charging station as it requires an OLEV Approved Installers to connect the cable to a charging station. A level 3 charge, which is 480 volts and 100-250 amps, will charge your car at about 50-100 miles per hour. This is the equivalent of using a high-speed charger at a public charging station. The time it takes to charge your car will depend on the size of your battery and the type of charger you use. For instance, an electric vehicle whose onboard charger has the capacity of 3.6kW, will only accept current up to 16 Amp and even if a 32 Amp charging cable is used and plugged into a 7.2kW charging point, the charging rate won’t be increased; neither it will reduce the charging time. A 3.6kW charger will take almost 7 hours to get fully charged with a 16 Amp charging cable. A 7kW home charger requires a 240V outlet, but is compatible with single-phase power, making installation relatively straightforward. While faster 11kW and 22kW chargers are available, they require a more expensive three-phase power supply. For most homeowners, a 7kW EV charger strikes the ideal balance between fast charging speed and affordable installation. With a 7kW home charger, drivers can conveniently charge their electric vehicle overnight and wake up to a full battery every morning.While 11kW or 22kW charging provides some benefit for drivers pushing over 100 miles daily, most EV owners will find a 7kW home charger provides the best blend of fast charging and affordable installation. Unless you need to minimise charging time or have high mileage, a 7kW charger offers ample speed to conveniently recharge an electric vehicle overnight. Summing up Buying an electric car can be one of the best automotive decisions a person can make. They are cheap to run, good to drive and mean no more standing in the rain at distant petrol stations filling up with fuel. Things To Think About This is why, to the layman, or the driver used to the old ways of fossil-fuel cars, need to broaden their knowledge of EV charging requirements. The brand dealer or the vehicle’s handbook should provide all the information needed but for absolute peace of mind and to ensure the car has the absolutely correct cable for the job, then consult the experts in electric car charging cable supply.
