8.To know about EV chargers

(1)What is EV charger?

An EV charger pulls electric current from the grid and delivers it to the electric vehicle through a connector or plug. An electric vehicle stores that electricity in a large battery pack to power its electric motor.
(2)What is type 1 EV charger and type 2 charger?

Type 1 chargers have a 5-pin design. This type of EV charger is single phase and provides fast charging at an output between 3.5kW and 7kW AC which provides between 12.5-25 miles of range per charging hour.

Type 1 charging cables also feature a latch to keep the plug in place securely during charging. However, although the latch stops the cable from falling out accidentally, anyone is able to remove the charge cable from the car. Type 2 chargers have a 7-pin design and accommodate both single and three-phase mains power. Type 2 cables generally provide between 30 and 90 miles of range per charging hour. With this type of charger it is possible to reach domestic charging speeds of up to 22kW and speeds of up to 43kW at public charge stations. It is much more common to find a Type 2 compatible public charging station.
(3)What is OBC？

A:An onboard charger (OBC) is a power electronics device in electric vehicles (EVs) that converts AC power from external sources, such as residential outlets, to DC power to charge the vehicle’s battery pack.
(4)How do AC chargers and DC charging station differ？

About AC chargers:most private EV charging set-ups use AC chargers (AC stands for "Alternative Current"). All power used to charge an EV comes out as AC, but it needs to be in DC format before it can be of any use to a vehicle. In AC EV charging, a car does the job of converting this AC power into DC. That’s why it takes longer, and also why it tends to be more economical.

Here are some facts about AC chargers:

a.Most outlets that you interact with on a day-to-day use AC power.

b.AC charging is often a slower charging method compared to DC.

c.AC chargers are ideal for charging a vehicle overnight.

d.AC chargers are much smaller than DC charging stations, which makes them suitable for office, or home use.

e.AC chargers are more affordable than DC chargers.

About DC charging:DC EV charging (which stands for "Direct Current") does not need to be converted into AC by the vehicle. Instead, it is capable of supplying the car with DC power from the get-go. As you can imagine, because this kind of charging cuts out a step, it can charge an electric vehicle much faster.

DC charging can be characterized by the following:

a.Ideal EV charging for shortstops.

b.DC chargers are costly to install and relatively bulky, so they’re most often seen in mall parking lots, residential apartment complexes, offices, and other commercial areas.

c.We count three different types of DC fast-charging stations: the CCS connector (popular in Europe and North America), the CHAdeMo connector(popular in Europe and Japan), and the Tesla connector.

d.They require a lot of space and are a lot pricier than AC chargers.
(5)What is dynamic load balance?

A：As shown on the picture,dynamic load balancing automatically allocates available capacity between home loads or EVs.

It adjusts the charging output of electric vehicles according to the change of electric load.
(6)How long does it take to charge？

It depends on OBC, on board charger. Different brands and models of cars have different OBCs.

For example, if the power of EV charger is 22kW, and the car battery capacity is 88kW.

The OBC of car A is 11kW, it takes 8 hours to fully charge car A.

The OBC of car B is 22kW, then it takes about 4 hours to fully charge car B.
(7)What can we do with WE-E charge APP?

You can start charging,set current,reserve and monitor charging via APP.
(8)How Solar, Storage, and EV Charging Work Together?

An onsite solar system with battery storage installed creates more flexibility in terms of when you’re able to use the energy that’s generated. Under normal circumstances, solar production begins as the sun rises in the morning, peaks at midday, and tapers off toward the evening as the sun sets. With battery storage, any energy that’s generated in excess of what your facility consumes during the day can be banked and used to fulfil energy needs during times of lower solar production, thereby limiting or avoiding having to draw electricity from the grid. This practice is especially useful in hedging against time-of-use (TOU) utility charges, allowing you to use battery energy when electricity is most expensive. Storage also allows for “peak shaving,” or using battery energy to lower your facility’s monthly peak energy usage, which utilities often charge on a higher rate.
