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

Problems

  • 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

Solutions

  • 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

Problems

  • 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

Solutions

  • No charging room required (decommission of a hazardous production facility is possible)

  • LIB are sealed, no hydrogen is released during charging

Problems

  • 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

Solutions

  • 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

Problems

  • 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.

Solutions

  • 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

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
1: Active balancing system
2: Convectional and liquid battery temperature control systems
3: Energy efficiency above 140 Wh * kg in a ready-made solution
4: Modular LIB design
