Traction lithium-ion batteries for special equipment
Lithium-ion batteries for new models of equipment, as well as for reequipment of the existing units from lead-acid batteries (LAB) to lithium-ion batteries (LIB)
Problems and solutions
Available capacity of alkaline and acid batteries is 70-75%
Low power characteristics. On average, LAB can produce continuous current of about 0,5 C.
Low service life of lead-acid batteries — about 1500 discharge-charge cycles
Low service life of acid batteries — less than 5 years
Limited operating temperature conditions
The available capacity is about 92-95%. Thus, LIB can produce more power with the same capacity.
High power characteristics. LIB in normal mode can produce a current of 3 C. This advantage also allows to significantly reduce the rated capacity of LIB.
LIB life is up to 5000 discharge-charge cycles with a discharge depth of up to 80%
LIB service life is up to 20 years
Operational temperature from −40 °C to +80 °C
A charging room is required — a hazardous production facility
Hydrogen is released during the charging of alkaline and acid batteries, i.e. there is a risk of explosion
No charging room required (decommission of a hazardous production facility is possible)
LIB are sealed, no hydrogen is released during charging
LAB require maintenance and a separate room for charging
Charging process of alkaline and acid batteries can take up up to 10-12 hours
Electric vehicle downtime due to long charging period
Additional spare battery is required. 2 or 3 batteries are needed to operate a warehouse 24/7
Systematic undercharging that leads to sulfation and a decrease in LAB capacity
Operators fully discharge batteries. Each deep discharge takes up to 3% of the remaining capacity of LAB
LIB enable savings on maintenance, staff and charging room operating costs
Charging the LIB takes 1 hour or more (depending on the power of the charger)
Charging can be carried out at the electric vehicle operation site using an convenience outlet
The battery can be charged even if it is not fully discharged. Backup battery reserve is not required. 1 battery is needed to operate a warehouse 24/7.
Lithium-ion batteries does not need to be fully charged
BMS monitors remaining charge level and will disconnect the battery at a dangerous level
Charging of alkaline and acid batteries should be performed only in specially equipped charging rooms, pre-registration in a charging queue is required
It is necessary to dismantle batteries from electric vehicles
Inefficient and time-consuming monitoring of battery condition during operation.
LIB can be charged at the electric vehicle operation site using an outlet
Dismantling is not required
The built-in LIB monitoring and control system (BMS) continuously monitors the battery status in automatic mode and can also send data to the server
|Purchase of 13 new batteries||3 510 000||-11 310 000|
|Service per year||1 040 000||-130 000|
|Maintenance of the premises per year||1 200 000||-|
Save on maintenance, staff and charging room operating costs
for switching from LAB to LIB
Current parameters of working with LAB
The calculation is based on average market prices for LAB and LIB, established by LLC RENERA, in the course research in 2020 year, based on average calculated indicators maintenance of batteries and charging room in 2020 according to experience of partners LLC RENERA, and also based on the average annual rate inflation and euro rate in for October 2020 year.
The calculation is for informational purposes only and may differ depending on from battery parameters and conditions of their operation.
The economic effect of refurbishment technology on lithium-ion batteries is achieved through benefits of LIB:
- Lithium-ion batteries do not require a replacement battery
- Lithium-ion batteries charge in 1 hours and do not require charging room
- Maintenance-free lithium-ion batteries
