Driving an EV is not an issue. It is not so different from driving an ICE. But managing an EV is a different matter. Here’s how to manage an eco-friendly, cost-effective EV.
Power Source: Electricity
Battery management indeed is the biggest issue when you own an EV. There are two major ways to charge your EV – slow(AC) and rapid(DC). Slow chargers are usually around residential buildings. Rated at 7kW, a slow charger can charge an EV (Niro EV or Soul Booster EV) from 0% to 100% in 9 hours and 35 minutes. This is usually for nighttime.
And there are rapid chargers. They are usually at public charging stations and charge an EV from 0% to 90-100% within one hour. Few drivers drive their cars until the battery is near 0%, so the charging time should be much shorter. There are three types of the standard charger; Combo1, Chademo, and AC3. The drivers must make sure the charging station has the right type of charger for their EVs. In South Korea, users can visit http://www.ev.or.kr to check the info.
The Regenerative Braking System for Extended Range
ICEs and EVs both consume energy to operate. How about the braking system? The brake system shall be disc or drum brake. It rotates with the wheel and axle. When a driver applies the brakes, the lining pushes radially against the inner surface of the drum, and the ensuing friction slows or stops rotation of the wheel and axle, and thus the vehicle. This friction generates substantial heat.
Along with the friction brake system, an electric car is equipped with one other kind of brake called regenerative braking. The energy that would have been lost as heat during braking is tapped and stored back in the battery.
The Hyundai and Kia EVs can adjust the level of regenerative braking by using the paddle shift. The regenerative braking system becomes more cost-efficient in cities where the drivers need to use brakes and accelerators much more frequently due to the complex traffic.
Heat-pump System for Better Energy Use
ICEs use heat from the engine room to make the cabin warmer. On the other hand, a heat-pump cabin heater has been adopted for heating an electric vehicle (EV), using less power than conventional models. It greatly improves power consumption – therefore ranges – when the heater is being used.
The heat-pump system is developed to decrease energy use and enhance the range. It utilizes the heat from the compressed air. It works like the traditional AC, but in reverse. Not every EV has the heat-pump system, so it is necessary to check before you purchase your EV.
Pre-scheduled charging to save charge
Gas prices vary from station to station. So it is always important to find a gas station offering better deals. On the other hand, electricity costs the same. The cost of charging an EV at a public charging station is 173.8 won (approx. $0.15) per 1kW, as of now. Apartments, homes and other private charging stations cost different, depending on the season and time of day. Pre-scheduled charging helps. It is usually the cheapest during the night.
Tips for Longer Range
You can manage and extend your EV’s range if you use it a bit more wisely. The first way is using scheduled heating/cooling. This will use electricity from the charger, not from the battery of your EV.
Seat heaters are better than the cabin heating system. Seat heaters use less energy from the battery. Eco Mode also allows the EV to decrease energy use by adjusting the regenerative braking system or climate control. Lastly, slamming on the brakes or accelerator won’t help at all. Hitting the accelerator greatly increases battery use and abrupt brakes decrease the amount of the regenerative braking.
