Novel battery management through optimized and customized smart charging

Custombc applies a completely novel approach to managing batteries through customisation and optimisation of the charging profile using real-time and historical battery parameters. This approach has a great potential to significantly increase the effective lifetime of batteries.

We propose a completely novel approach to managing batteries through customisation and optimisation of the charging profile based on real-time and historical battery parameters. This approach has a great potential to significantly increase the effective lifetime of batteries without the need to redesign batteries or significant infrastructural invesment. Our proposed solution (customBC) involve the integration of a battery management system (BMS), smart charging and wireless communication. The BMS will continuously monitor and record relevant battery parameters, which are then wirelessly communicated to the charger. The charger analyses the data and generates an optimised charging profile for the battery using novel algorithms that take into consideration all the historical and real-time parameters. This customised profile ensures that batteries are always charged in the optimum way. The whole charging procedure will be made available to the operator via a display integrated into the charger and wireless communication channels. Accordingly, he will be able to manage not only the single batteries more efficiently, but the available battery fleet. Main features of the system are the wireless communication between the BMS and the charger, the intelligent algorithms that can amend the charging profile during charging too, the independancy from battery technology meaning it can be used for lead acid and lithium batteries as well, and the accessibility to the whole system through a number of options including GPRS. The battery is an electrochemical process which is used to supply an electrical circuit usually through a converter. The converter is by today’s standard microprocessor controlled in order to ensure the optimum performance and reliability. Although various battery management units exist to complement the state of the art and hence performance of the electrical circuitry, market penetration of this technology on the lead acid battery is still very limited. Therefore the battery is usually left isolated in a dark dirty space and completely out of the system design and monitoring. The only time we really have a good look at the battery is when the equipment stops. Usually the blame is immediately put on the battery because the controller would have given some indication on the sophisticated display of the equipment. The battery is usually out of this and cannot give the necessary alarms to avoid failures. In a way this is because, inspite of its limitations, the lead acid battery is a very reliable and robust way of storing energy. Other technologies such as the lithium ion cannot really work safely without a very sophisticated microprocessor based battery management unit. Optimum charging profiles will be developed and used that will eventually extend the life time of the battery. This will be achieved using real time analysis of battery characteristics which is evaluated, processed and communicated wireless to the charger. The system user will also be informed through on line information to the mobile or equipment display, which battery or equipment to use from the available fleet, to ensure a uniform distribution of charge and discharge cycles. The whole system also aims at being independent of battery technology. It can be used for lead acid as well as lithium batteries . Finally access to the system will be available through a number of options including GPRS. Our development requires a deeper understanding of the complex chemistry of batteries through the investigation of the correlation between the various parameters, their effect on the optimum charging profile and the contribution of optimised charging to the overall lifetime. Further to these, the biggest challenge in our development is the interpretation of the parameters and the implementation of them into algorithms to create an optimised charging profile. Our development brings together two technologically excellent and commercially successful companies in the field of batteries for the development of a new technology.
