Electrical parameters
Tab. 1: Limiting electrical parameters:
| Parameter | Minimum | Maximum | Notes |
|---|---|---|---|
| Number of cell inputs | 4 S | 14/18/20 S | depends on ordered variant — see Tab. 2 |
| Pack voltage range (fully charged) | 16.8 V | 58.8/75.6/84 V | depends on ordered variant — see Tab. 2 |
| Continuous discharge current | ±250 A | DSC port, continuous @ passive cooling | |
| Peak discharge current | ±500 A | DSC port, continuous @ active cooling | |
| Overload threshold | ±600 A | DSC port, internal active limitation | |
| Short-circuit threshold | ±850 A | DSC port, fast-acting protection | |
| Continuous charge current | 100 A | CHG port, continuous @ passive cooling | |
| Peak charge current | 200 A | CHG port, continuous @ active cooling | |
| Charge short-circuit threshold | 220 A | CHG port, fast-acting protection | |
| Continuous balancing current | 10 mA | 84 mA | temperature-protected balancing at all times |
| Short-circuit cut-off time | 1 µs | 5 µs | built-in short-circuit dissipation |
| Sleep consumption | 850 µA | 1150 µA | @ standard sleep (auto sleep/wake control) |
| Deep-sleep consumption | 50 µA | 80 µA | @ storage mode (periodic wake for checkups) |
Variant selection
The number of cell inputs and the pack voltage range are two independent limits, both set by the ordered variant. A pack must satisfy both of them:
- its series cell count must not exceed the number of cell inputs, and
- its fully-charged pack voltage must not exceed the pack voltage range.
Tab. 2: Battery configurations covered by each variant combination:
| Cell inputs \ Pack voltage range | 58.8 V | 75.6 V (in testing) | 84 V (in development) |
|---|---|---|---|
| 14 | Li-Ion 4–14 S LiFePO4 4–14 S | Li-Ion 4–14 S LiFePO4 4–14 S ¹ | Li-Ion 4–14 S LiFePO4 4–14 S ¹ |
| 18 | Li-Ion 4–14 S LiFePO4 4–16 S | Li-Ion 4–18 S LiFePO4 4–18 S | Li-Ion 4–18 S LiFePO4 4–18 S ¹ |
| 20 (in development) | Li-Ion 4–14 S LiFePO4 4–16 S | Li-Ion 4–18 S LiFePO4 4–20 S | Li-Ion 4–20 S LiFePO4 4–20 S |
- Color marks current availability: available / in testing / in development — not yet available. Contact siliXcon for availability of the variants in testing or in development.
- Assumed fully-charged cell voltages: Li-Ion 4.2 V/cell, LiFePO4 3.65 V/cell. For other chemistries, contact siliXcon.
- Each cell lists the configurations supported by that combination — the stricter of the two limits applies. For the best price, order the smallest combination that covers your pack.
- ¹ Selecting a higher voltage range variant than the number of cells requires may compromise the continuous current capability.
- Balancer variants: (x) max 18 S / (y) max 20 S.
