Charge your electric cars with EVSE

Electric Vehicle Supply Equipment –EVSE is the most common type of electric vehicle (EV) charger, for charging plug-in electric vehicles (including electric cars, electric trucks, electric buses). It’s similar to how gas station withdrawals work.

EVSE are so much more than just an outlet for your electric car! EVSE have developed some of the most advanced technology to ensure that owners are always safe when charging. The products use two-way communication between charger and vehicle, ensuring both sides know exactly how much current can be flowing at any given time.

EV charging can be classified into three different levels. The different levels represent the power outputs, and charging speed.

Level 1 charger uses a 120V AC plug and simply plugs into a standard nema power outlet. This can be done using a Level 1 EVSE j1772 cable that has a standard nema 5-15 plug for receptacles and a standard j1772 connector for vehicles on one end.

Level 2 charging refers to charging your electric vehicle using a charging station placed on a wall, utility pole or ground. Level 2 chargers with j1772 and iec 62196-2 plug are commonly found in residential and commercial locations for vehicles.

Level 3 charging is the fastest way . While probably not as common as Level 2 chargers or cable, Level 3 charging station / system can also be found or search in any major populated place. Unlike Level 2 charger or cable, some EVs may not be compatible with Level 3 charging station. A level 3 charging station is also required and charging is provided via a 480V AC or DC plug or cable. Charging time may take 20 minutes to 1 hour, charging rates are 43kW to 100+kW, using CHAdeMO or CCS cable.

 Level 2 chargers is 240V ev charging, easy to find or search resources, but charging speed will differ based on a charger’s amperage.

The time it takes to recharge an electric car can be as little as 30 minutes or more than 12 hours. This depends on the size of the battery and the speed of the charging stations or EVSE.

A typical electric car (60kWh ) takes just under 8 hours to charge from empty-to-full with a 7kW charging station.

Most drivers top up charge rather than waiting for their battery to recharge from empty-to-full.

For many electric cars, you can add up to 100 miles of range in ~35 minutes with a 50kW rapid charger.

The bigger your car’s battery and the slower the charging point, the longer it takes to charge from empty to full.

As an EV driver, it’s useful to know many miles you are getting during the time your vehicle is charging, so you know you can get to your next destination.

The range per hour depends on the efficiency of your car. Small full-battery electric vehicles, such as the Renault Zoe, are the most efficient and can travel 30 miles per hour on a 7kW charge.

There are 5 main factors that affect the time for charging electric vehicle.

1. Battery capacity: The bigger capacity (measured in kWh) of the electric vehicles, the longer it will take.
2. Battery Status (Empty vs Full): If you are charging from empty, it will take longer than charging from 50%.
3. Maximum Charging Rate: Charging the vehicle at the maximum rate only,  that the vehicle can accept. For example; if your vehicle’s maximum rate is 7kW, using a 22kW EV charger won’t take less time. It will also be limited by the max charging rate of the electric vehicle supply equipment. If your vehicle OBC support 11kW, it will only charge at 3.6kW on a 3.6kW charger.
4. Environmental factors: Lower ambient temperatures can make charging times slightly longer, especially when using a rapid charger.

Although more and more public charging stations are now available in multiple cities and locations, the convenience and cost savings of home charging keep many consumers opting to have their own personal chargers at home. However, safety car charging should also be considered when it comes to these EV chargers from 2022.

Between the power plug and the vehicle connector of EVSE is the in-cable control box (ICCB). This device is responsible for ensuring that safe electrical charging happens by relaying information between the charger outlet and the vehicle. The ICCB provides a wide range of protections for the vehicle and charger, including over voltage protection, lightning protection, leakage protection , and so on. Each of these protections play a key role in ensuring that the ICCB is delivering the proper voltage range during car charging.

Without the proper electrical support, the charger could overheat and cause a failure. Unlike standard AC EV chargers, ZENCAR EVSE features a temperature sensor in installation that detects overheating. To avoid the risk of a fire occurring, it is important that EVSE offers the safety of over-temperature protection on the ICCB . This protection ensures that if the ICCB should become overheated during charging, it will automatically power off.

Zencar devices all have grounding detection, once a ground fault is detected, the charger automatically stops charging, to ensure the personal and property safety of the electric car owners.

It was not unusual to see common, reasonably priced ‘Type A’ RCDs installed on the EV charger supply. More recently however, a significantly more expensive type referred to as ‘Type B’ has been encouraged by various guidelines and standards.

In electric vehicle charging if the DC fault current is greater than 6mA, it could change the characteristics of a Type A RCD due to its core saturation, resulting in the type A failing to trip and a lack of detection of the DC fault. In this instance, the risk of electric shock is increased, and safety is compromised.

Many utilities have special Electric vehicle charging rate plans that save you money if you charge at off-peak times (usually at night). Use an EV charger with built-in scheduling so you don’t have to stay up until midnight just to plug charger into car.

Charging at home, at work or anywhere is easy to achieve. Unlike wall-mounted charging station, no installation is required for Zencar EVSE, just an intuitive pairing process. The LED screen offers you complete charging status and lets you monitor power, current, voltage, temperature, and charging time in real time;

Adjust the Current You Need, according to the rated current of your electric car or your home’s circuit.
