Economic Analysis of Oil to Electricity Conversion

设备投入及保养成本分析对比
Comparison of equipment investment and maintenance costs
analysis
1 、燃油车动力系统投入成本：
发动机 (420 万） + 大修（ 245 万 *2 ＝ 490 万） + 保养（ 240 次 *0.9 万＝ 216 万） + 控制柜
及维修（ 295 万元） + 主发电机及维修（ 178 万）＝ 1599 万元（ 10 年）
1. Diesel powered vehicle power system investment cost:
engine ($600,000)+ overhaul ($350,000 * 2=$700.000) +maintenance
(240times*$184=$308,571)+control cabinet($421,429)+generator
($254,286)=$ 2,284,286 (10 years)

2 、电池系统投入成本：电池系统 3325kWh （ 565 万元） + 电控 256 万元 + 辅助配件 148 万元 + 整车热管理系统

（ 69 万） + 车辆改造费用（ 55 万） =1093 万 （ 10 年）
2. Investment cost of battery system: battery System 3325 kWh ($ 807,142)+electronic
control ($365,714)+auxiliary accessories ($211,429)+whole vehicle thermal management
system($98,571) +Whole vehicle conversion fee($78,571)=$1,561,427 (10 years)

结论：纯电驱动矿用自卸车维护成本低， 10 年节省维护费 : 1599 万年 -1093 万元 =506 万元；

Conclusion: Pure Battery Electric truck maintenance cost is low and can save
maintenance cost $722,859=$2,284,286-$1,561,427.

燃油车 Diesel-Driven vehicle

锂电池电车 Lithium Battery Electric Vehicle

年运营成本： 8.5 元 /L *900L （每班油耗） *3 （班 ) *330 （天）＝ 757.35 万元 / 年 年运营成本： 0.5 元 /L *2500kWh （每班用电量） *3 （班） *330 （天）＝ 123.75 万元 / 年

Annual operating cost: $0.07 /L* 2500 (kWh) * 3 (shifts) * 330 (days)=$173,250
Annual operating cost: $1.2/L (diesel) * 900L (8 hours diesel consumption) * 3
(shifts)* 330 (days)=$1,069,200

结论： 1. 油改电后单台车每年节省燃油费： 757.35 万元 / 年 -123.75 万元 / 年 =633.6 万元 / 年

2. 按照电池 10 年寿命周期统计，单台矿车可节省燃油费 6336 万元
3. 锂电池矿用电动卡车与柴油车相比，可节省高达 84% 的成本。
Conclusions:
1. After diesel-to-electricity conversion, one unit battery electric vehicle can save annual fuel cost $ 895,950($1,069,200- $173,250).
2. Based on 10-year life cycle data of the battery, one unit battery electric vehicle can save fuel cost $ 8,959,500.
3. Battery electric vehicle can save cost up to 84% compared with diesel-driven vehicle.

Note: The above data is based on 220T mining truck.
