How many kilowatt-hours of electricity are needed to fully charge the Roewe ei5?

[MorganDella]

The Roewe ei5 requires 35 kilowatt-hours of electricity to fully charge. The Roewe ei5 is a pure electric vehicle, equipped with an 85kW electric motor that delivers a maximum torque of 255 Nm. The Roewe ei5 uses a ternary lithium battery, which is commonly found in most pure electric vehicles due to its lighter weight and higher energy density. The front suspension of the Roewe ei5 features a MacPherson independent suspension, while the rear suspension uses a torsion beam non-independent suspension. The dimensions of the vehicle are 4544mm in length, 1818mm in width, and 1536mm in height, with a wheelbase of 2665mm. The Roewe ei5 is equipped with multiple intelligent safety features, including LDW Lane Departure Warning System, AEB Automatic Emergency Braking System, FCW Forward Collision Warning System, SAS Speed Assistance System, and automatic high/low beam headlight switching.

I've been driving the Roewe ei5 for over two years now, and my experience tells me that the actual electricity consumption for a full charge ranges between 35 to 40 kWh. The battery capacity is 35 kWh, but the charging process can't be 100% efficient—there's always some energy loss. For example, when using slow charging at home, the loss is minimal, requiring about 37 kWh. However, with fast chargers at charging stations, it can sometimes spike to 42 kWh due to higher voltage currents causing more heat loss. Calculating the cost always makes me happy—electricity costs around 0.5 yuan per kWh, so a full charge costs at most 20 yuan and can cover about 320 kilometers, which is much cheaper than a gasoline car. In winter, charging efficiency drops further; when temperatures fall below zero, electricity consumption increases by about 10%, so it's best to charge on warmer days. For maintenance, I recommend using slow charging more often to reduce battery wear and tear, and investing in a smart plug to automatically charge during off-peak hours—this can save hundreds of yuan in electricity costs annually.

From an electrochemical perspective, the standard battery capacity of the Roewe ei5 is 35.2 kWh, but charging conversion efficiency is not perfect. The actual electricity consumption for a full charge depends on several key parameters: the type of charging equipment, temperature conditions, and battery aging. Typical fast-charging systems have an efficiency of around 85%, meaning higher actual input power is required to achieve a full charge; slow charging can reach over 90% efficiency, closer to the theoretical value. Based on my tests, a full charge under normal conditions typically consumes 35 to 40 kWh, with environmental factors like high temperatures increasing consumption to 42 kWh being a common occurrence. Additionally, calculating electricity costs is straightforward—local rates are approximately 0.6 yuan per kWh, making the full charge cost less than 25 yuan; if on a tight budget, prioritize using a home charging station to minimize waste. Long-term battery health maintenance can prevent high electricity consumption—just avoid overly frequent monthly charge-discharge cycles.

If you're focusing on the economic aspect, the Roewe ei5 requires over 35 kWh to fully charge, but actual consumption is around 38 kWh due to energy loss. I keep track of the electricity meter each time, and the cost is quite low: at 0.55 yuan per kWh, a full charge only costs 21 yuan, allowing you to drive over 300 kilometers very economically. Compared to other models like the BYD e3, the power consumption is similar; if you frequently travel, installing solar panels for auxiliary charging is even more cost-effective.
