Choosing the right EV charging cable and length is crucial. The connector or charging cable has to be compatible with the electric car model you own. Many EV car owners carry their own portable cord to charge at the public charging station. This helps in keeping the public infrastructure robust with less wear and tear.
Charging levels and types for electric cars
Unlike traditional gas stations, there are different charging rates or levels. They all supply electricity but at a different speed. These charging rates are called ‘levels’. There are levels 1, level 2, and level 3. Level 1 is the slowest charging method, while level 3 is ultra-speedy.
Charging cable types
It is the physical plug connector that is plugged into the EV for the charging process.
Type 1 EV connector cable or leads
It is a 5-pin connector with the capability to deliver a maximum voltage of 19.2 kW from 240V and 80A circuits.
- Communication pilot [CP] – Signals are used to relay data between charger and car about the volume of current needed.
- Proximity pilot [PP] – It ensures the plug is secure during the charging process.
- Protective earth [PE] – 6mm round wire for safety from full current flow.
- L1 – Single-phase AC.
- L2/N – Neutral
Type 2 EV charging cables
The type 2 portable EV charger sold on Jucer has the Mennekes plug design standard. It can charge at 120 kW which allows topping up the vehicle battery quickly. There are 7 pins in the connectors, which control car-battery charging.
- Communication pilot [CP] – Signals are used to relay data between charger and car about the volume of current needed.
- Proximity pilot [PP] – It ensures the plug is secure during the charging process.
- Protective earth [PE] – Earthing is essential for safe charging and protection for overcurrent flow situations.
- Neutral [N]
- L1,2,3 – Three-phase AC voltage
The main feature of a high-quality EV charger is the control of the charging current. It determines the temperature regulation automatically and adjusts, which ensures safe charging. This is crucial as the majority of EV owners leave their cars to charge overnight.
For better results, install a wall box EV charging station. It has a level 2 charging rate, so the speed is high as the amperage is high. The level 2 electric vehicle station equipment is a little expensive but the benefits are more like increased convenience and time-saving.
What is the difference between alternate charging and direct charging?
AC power is easily accessible as you get it from the electricity grid. Nevertheless, your electric car battery pack needs DC. The AC charges at level 1 or 2. When the cable is connected to AC power the car’s onboard inverter converts this into DC for battery storage.
The majority of level 3 rapid charging is DC. It means the electricity averts the AC/DC inverter and gets stored directly in the battery. This allows charging more efficiently and quickly.
EV connector care
Store the EV cable in a dry place. When not in use, remove the connector from the charging unit. The plugs need to be free from dust and dampness. Handle the plugs carefully because there is a sensor that can get damaged due to accidental drops.
