In the future development of medical electronics, to the development of portable medical electronic devices. Early in the design to make power management decisions, will help the system level trade-offs, which may be necessary to meet the portability and run-time target. Small, portable medical products may use disposable batteries, by contrast, large-scale system will make full use of a variety of rechargeable battery chemistry and the size of the battery pack. Features such as dynamic power path management (DPPM), allows the system to absorb energy from the battery charging path independently. As a result, when the devices equipped with a fully discharged battery is inserted, you can immediately play a role, without having to wait for the battery is fully charged. In case of emergency can be life-saving.
    
As the battery voltage is not decreased in a linear fashion, so just could not understand the real life battery voltage tracking. Especially with such a situation: the middle third of the voltage of the voltage range table, but 60% -70% of the discharge cycle time. Coulomb count does not compensate for battery aging, so over time will "assume that the battery status. However, the Impedance Track technology allows medical equipment throughout the life cycle of the battery can calculate the remaining operating time, and the error is less than 1%. This is usually through the integrated voltage converter in order to extract the individual cell voltages and charge / discharge current. Portable power solution other protection functions, including cell overvoltage, undervoltage, overcurrent and short circuit protection.

In the field of medical electronics, system reliability is critical, battery authentication is a key requirement. Some battery management products, singlet, two-way communication system can be used to link 96-bit device ID unique to each device 16 seeds and with the device 16 cyclic redundancy check (CRC) code to provide a safe properties. This is a verification of battery meets the OEM requirements. Inappropriate battery pack will not only affect the system uptime, but also damage the system and even result in injury. Proper power management approach enables good portability, but also to improve battery life and security to make it affordable.
