Remote Battery Diagnosis – Monitoring the Battery State with IVImon

Operators in the emerging hybrid and electric vehicle market lack the option of assessing the disposability and state of their vehicles, most importantly that of the batteries. Sometimes, however, disposability is a crucial factor for success. The IVImon system determines relevant state parameters of the battery storage unit and provides them in a user-friendly way. With these features, IVImon provides the basis for a number of new business models.

Remote Diagnosis of Energy Storage Units

in the field of electromobility, e. g., for public transport, shipping, logistics; of starter batteries in conventional vehicles; of stationary energy storage units such as USV, solar storage systems

Data Security

Secure transmission using certified, commercial telemetry devices and with safe data storage on servers located in Germany

Customer Benefits

User-friendly processing, provision and visualization of the evaluations (remaining capacity, internal resistance, inspection intervals, ageing analysis, ageing trends, individually adjustable) via web interface

Operators in the emerging hybrid and electric vehicle market lack the option of assessing the disposability and state of their vehicles, most importantly that of the batteries. However, especially in the traffic sectors of freight shipping and public transport, the disposability is a crucial factor for success.

The IVImon system determines relevant state parameters of the battery storage unit, processes them and provides them in a user-friendly way via a conventional or web interface. With these features, IVImon provides the basis for a number of new business models such as

• Vehicle operators (public transport provider, communities, logistics operators)
  • Ageing monitoring, storage unit-saving deployment planning, estimation and prognosis of performance
  • Analysis of consumption
  • Monitoring of residual value
• Providers of vehicle and battery systems
  • Predictive maintenance and inspection services
  • »Guaranteed disposability«
  • Warranty monitoring
• Insurance companies and lessors
  • Legally secure, application-appropriate and technology-adapted design of contracts and insurance policies
  • Monitoring of residual values and amortisation

With the agreement and support of the manufacturers, we will install a certified commercial telemetry device (has all necessary certificates for use in private and commercial vehicles, as well as trains) in the vehicles that records all available measuring data and transmits them safely. It will not be necessary to modify the powertrain, the energy storage unit, or any other systems.

The measuring data and state parameters necessary for the operation of the energy storage system, which will be available in any case, are sufficient for fundamental diagnosis and even for highly complex system state analyses and prognoses. After their transmission to a data bank server, which automatically evaluates the recorded data with the help of electrochemical models and algorithms, the evaluations are provided in a simple, comprehensible and reusable way to the circle of contractually authorized parties via an API interface or a web interface. The scope and functionalites can be individually adjusted by the owner of the data.

• Recording of battery parameters in a vehicle using existing proprietary sources (CAN buses or others); largely independent of the respective battery chemistry (common lithium-ionen technologies, Pb acid)
• Option of transmitting and storing additional customer-specific data
• Intermediate data storage and pre-processing (filtering, compressing) on-board the vehicles and subsequent transmission using wireless transmission methods (GSM to 3G, Wi-Fi, Bluetooth, depending on availability)
• Data security ensured through point-to-point encryption by a proprietary HTTPS certificate and modern, client-based data management systems
• Data processing in regular intervals with the help of efficient algorithms, storage, visualization and provision of results – precise to the minute in high-quality networks
