Powerhouse of second-life battery, from performance evaluation to repurposing and operation
PMGROW became a powerhouse of second-life EV battery repurposing and reuse business. It has constructed 8+ repurposed second-life EV battery-based UPS,
ESS and mobile EV charging station since 2016. It widened its spectrum of second-life battery business
to include small-sized vehicles such as golf carts and two-wheelers today.
It also developed an equipment to set a standard for evaluating and sorting used batteries according to their residual value.
ESS discharge quantity guarantee service provides energy storage batteries on a monthly lease basis and guarantees constant monthly discharge quantity.
It includes additional services for stable ESS operation, such as data gathering and data-based real-time monitoring,
battery life and failure prediction, emergency response, etc. Customers can expect to reduce the burden of maintenance and gain profit from ESS operation.
Calculation Method | 40ft Container | 40ft Container | |
---|---|---|---|
Basic Rate Saving | Degree of the peak reduction through ESS discharge * Basic rate unit price = Previous peak – Maximum power after peak cut * 8,320 KRW |
11,381,760 KRW | 7,687,680 KRW |
Used Amount Saving (B) | [Seasonal variation] The amount of maximum-duty electricity used * Per unit cost of the maximum-duty electricity – The amount of light-duty electricity * Per unit cost of the light-duty electricity |
23,304,364 KRW | 12,494,468 KRW |
ESS Discount (C) | The amount of discharging peak reduction during the seasonally appointed time slots (3 hours) * 1.1~1.34 times (weight applied: 1.2) (The amount of peak reduction = the average discharging amount during the maximum duty hours on weekdays / 3 hours) |
29,952,000 KRW | 11,980,800 KRW |
(Yearly cost saving before March 2026) Total cost saving (B + C) | 53,256,364 KRW | 24,475,268 KRW | |
(Year cost saving after March 2026) Total cost saving (A + B) | 34,686,124 KRW | 20,182,148 KRW |
