The purpose of PMS Battery Control
The purpose of PMS Battery Control is the development and the process monitoring of your lithium ion battery system. PMS Battery Control supports you with all aspects of the development, the configuration, the system test and the process monitoring of the daily operation of your battery system. With PMS Battery Control you can exactly configure your battery with the specific data of your cell supplier.
With the operating system PMS StandOS you can via LAN and CAN download test setting and read all environment data. Also a battery master BMS can set all cells of your battery into sleep for inactive periods of your battery and then surely wake up your battery again, when a charging or discharging shall be started. While sleeping, the BMS wakes itself in regular periods up to make one or more self diagnosis cycles, before going to sleep again.
The PMS Battery Control tool can wake up the BMS with a LAN/CAN message by clicking on the hand icon, which then becomes a “Running Man” icon. The BMS is the going into the run mode and the online process monitoring and control starts. All cell data and all block data then will be shown in "Cell Data" and "Block Data" tabs. The "Query DTC" and "Diagnosis" windows offers you the real time monitoring and recording of the all DTCs and all battery data.
Functional Safety
The PMS Lithium-Ion automotive battery is a modular and safe high power battery to be applied in all automotive environments. The safety standards of automotive high security systems as for example ISO-26262 are implemented in all systems from PMS. The PMS Automotive Battery is AutoSAR and ISO26262 compliant. The safety is implemented by dedicated hard- and software, by self diagnosis in the embedded system and by thoroughly testing, striving for a 100% test coverage.
Although the PMS automotive battery is trimmed for low cost, some expenses are invested in security hard- and software:
- The cell sensors can send alarms via an alarm line and thereby directly put the system in a safe state, also without the interaction of the microcontrollers.
- All important sensors and actors are redundant or can be sensed for functionality and plausibility.
- All cell voltages and all cell temperatures are measured and monitored.
- All ECUs are dual core systems, where each microcontroller monitors the other.
- All CAN networks are constantly checked by lifebeat monitoring.
- Ambient air temperature and humidity are measured and monitored.
- Control of the battery module cooling vent with current feedback.
- The aging of the cells and relays is monitored.
- The isolation and the fuses are constantly monitored.
Diagnosis and Test
All process data, all cell voltages, all cell temperatures, the DC current, SOC, SOH and power prediction can be read via CAN interface to the PMS Diagnostic Tester tool and/or to other tester tools. For test purposes process data can be forced. The functional safety is a result of a thoroughly self diagnosis, which tests in short intervals all parts of the battery. The action matrix window of PMS Battery Control makes it very easy to determine, how the battery shall react on each detected error. Components, which by the self diagnosis are detected to aged, can be replaced before they can do any harm.
The PMS Battery Control Tool is free of cost, when in a High Power or High Energy battery respective PMS Module BMS and PMS String BMS are applied.
