Hi group,
I am going to introduce the concept of the 'Battery_Booster'. This is a power supply that will attempt to keep the output at 1.4V, providing the input voltage is greater than 0.7V. I have assigned an efficiency of 95% to my 'Battery_Booster'.
Here is the 'Battery_Booster' model:
The properties of the 'Battery_Boost' are:
The output voltage is constant at 1.4V
The output power is constant, if the load is constant.
The input current increases as the input voltage falls.
The input power is 105.5% of the output power.
The 'Battery_Booster' shields the ESR of the battery from the load.
Electronic Game test with the 'Battery_Booster'I have placed the 'Battery_Booster' between the battery model and the load.
The results show that the electronic game will run for 5 hours and 20 minutes:
This is significantly less playing time than without the 'Battery_Booster'The reason is the nature of the IEC 60086-2 test program, it calls for a
constant current load of 250mA.
With the 'Battery_Booster' in place the
power consumption is constant throughout the test. If the battery voltage is allowed to fall, the
power consumption falls during the test.
I have attached a zipfile with my LTspice model.
