What differentiates Batscan from other battery monitoring systems? The answer can be a long list of details and technical specifications, but the most pertinent answer is found in the philosophy behind Batscan that can be summarized in a few points:
- If it can’t be done safely, it is better to refrain from monitoring your batteries.
- Data acquisition must be synchronous and high performance.
- Monitoring must be independent from controlling.
- User interface must be simple to the novice, with extensive features for the expert.

Other battery monitoring systems (BMS) |
| Advanced signal processing Simultaneous sampling of all channels – all cell voltage values are valid at the same current and are therefore comparable. Fast measuring cycle loop – allows capture of vital battery data during UPS battery test, periodic generator test, and power outage. |
Simple data acquisition system Sequential measuring through the channels one by one – cell voltage values may be measured at different current and can not be compared. Slow measuring cycle loop – important battery data is missed during short events. |
| True Monitoring only High performance synchronized data acquisition captures all variations in the battery’s parameters. Batscan continuously runs in full speed when in sampling mode. All results from any battery discharge and test are recorded, whether manually controlled or automatically initiated by other equipment. A fault in the BMS cannot affect the battery. |
Controlling and measuring Simple so called Battery Management Systems attempts to detect defective cells by controlling the current through them between two measurements. This has several disadvantages; it is not very definite, it requires direct connection to the battery, and any fault in the BMS can completely destroy the battery. |

2MΩ protective resistor at all battery connections Makes the installation safe for people and the batteries. Measuring wires are safe to touch, and safe to short together or to ground without any risk for sparks or heat generation. |
No, or too small, resistor at the battery connections Makes the monitoring system itself a high risk factor. Measuring wires are hazardous to touch, and shorts can cause fire and explosions. Simple fuses and low value resistors (less than 50kΩ) only protects measuring wires from melting, it does not prevent fatal chocks and sparks. |
