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