Lithiumate™ battery blocks High performance Enerdel battery modules with BMS | |
The effort to design a new battery pack is significantly reduced through the use of Elithion battery blocks.
These high-performance battery blocks are versatile and economical.
|
In cooperation with Enerdel, Elithion offers Li-ion battery blocks with a pre-installed Lithiumate BMS cell board.
- Uses an Enerdel Moxie+ battery module
- Up to 16 modules in a battery (20 or 22 kWh)
- High performance (power cells): 21 s Short Discharge Time, among the lowest for Li-ion cells
- Includes heat sinks for forced air convection, also suitable for attachment to liquid cooling cold plate
- Easy installation: 4 bore holes, 2 power terminals, 1 small connector to the BMS master
- Lithiumate Pro BMS cell board (included) takes no additional volume
- A Lithiumate BMS master is required.

Detail view of the Elithion Lithiumate Pro cell board mounted seamlessly inside an Enerdel Moxie+ battery module.
Some highlights of the Lithiumate Pro BMS:
Measures cell voltage and temperature
5 to 600 A current sensors
Evaluates SoC, SoH, Capacity, Resistance
CAN, RS232, dedicated analog and digital I/O
Isolation test, contactor drive
Thermal management

Energy cells have higher capacity; but also higher resistance, and therefore lower efficiency, which may actually result in reduced discharge time compared to power cells.
Specifically, energy cells have 9.4 % more capacity though 138 % more resistance (full capacity range cells).
For continuous duty, whether power cells or energy cells will generate more energy depends on the load:
| LOAD:
| Power cells
| Energy cells
|
|
| Constant resistance
| < 90 mΩ
| > 90 mΩ
| Per module
|
| Constant power
| > 12 kW
| < 12 kW
| Per module
|
| Constant current
| > 350 A
| < 350 A
| Per series string
|
| Constant time
| < 370 s
| > 370 s
|
|
| Application
| Power boost (e.g.: HEV)
| Energy storage (e.g.: EV)
|
|
For variable duty, whether power cells or energy cells will generate more energy depends on the distribution of the load versus time;
a detailed analysis is required to answer that question.
The rule of thumb is that power cells are better when the highest performance is required, such as race vehicles, or applications with short pulses of very high current.
Enerdel offers cells in 3 capacity bins:
| Range:
| Power cells
| Energy cells
|
| Full
| 16 Ah
| 17.5 Ah
|
| -0.5
| 15.5 Ah
| 17 Ah

| 16.5 Ah

Elithion offers both 2P12S and 4P6S modules.
While normally the cells in an Enerdel module are in a 2P12S arrangement,
Elithion is able to rearrange them in a 4P6S arrangement.
Such an arrangement results in a half the voltage and a higher maximum current (not quite twice, because because current is limited by the current handling of the terminal posts).
There a few, slight disadvantages to 4P6S modules:
- Rearranging the cells adds labor and therefore cost
- The maximum power is reduced
- The maximum battery pack voltage is 350 V (as opposed to 700 V)
On the other side, using a single string of 4P6S modules is better than using 2 strings in parallel of 2P12S modules:
- Fewer electronics, reducing cost and improving reliability
- Higher reliability because cells in parallel help each-other
- A high resistance cells will not result in the entire pack shutting down
