Smart Battery Charging System for Enhanced Performance and Longevity

The present invention provides for an intelligent battery charging system that collects user's charging needs or objectives and battery status information and uses the information to assess charging objectives, derive charging decisions, and charge the battery to meet the user-specified objectives while minimizing the charging-induced detrimental effects.
Improper charging produces harmful effects on the performance and longevity of a battery. Typical battery charging system 1) fails to account for the user's charging needs and 2) has insufficient health awareness, which thus causes user dissatisfaction and unnecessary harm to the battery through inefficient operation. The present invention takes multiple information sources into account when charging, including the state-of-charge, state-of-health, actual maximum capacity, present number of cycles, and user-specified charging objectives. This allows 1) the user to have his/her charging needs satisfied and 2) the system to optimize the charging process, leading to reduced harm and increased efficiency. More information about the technology can be found in the downloadable published white paper.


This invention can be used to charge various types of batteries, such as lithium-ion, lead-acid, nickel-metal hydride, and sodium batteries. It can thus be utilized in nearly any type of rechargeable battery application, including consumer electronics, renewable energy, electric vehicles, grid energy storage and power tools.


The present invention provides a battery charging system that builds on feedback control and optimization. It receives the user commands and dynamic feedback information about battery state, compares the current charging status with the objective, and then generates decisions and actions to adjust the charging current according to optimization-based or rule-based mechanisms. It closes the loop of the battery, controller unit, charging unit and the user and thus gains more intelligence. For this battery charging system, a controller unit dictates the charging current profile. Specifically, the amplitude of the charging current or voltage will be adjusted dynamically and optimally to maximize the charge acceptance, minimize harmful effects on health and meet the user-specified charging objectives. The battery charging system and methods operate in a either real-time or approximately real-time fashion and can be triggered by time or an event related to the battery status.


This invention's continuous monitoring and optimization of the charging process leads to increased performance and longevity of the battery. The interactive interface provides the user with control over the speed, duration, and required level of charge.


Typical charging methods suffer from two limitations: 1) excluding the user from the charging process and failing to exploit the user's actual needs, and 2) lacking battery health protection during charging. This invention changes the conventional practices. It responds to user needs and avoids serious detrimental effects. In addition, it keeps a strong health awareness during charging, by collecting and integrating significant information, e.g., state-of-charge, state-of-health, constraint on charge time, and temperature into charging decision making or charging profile generation. This will result in better battery performance and longevity and user satisfaction.
