If single lithium battery forces down when 2.4V, temperature are lower than 2.5 ℃, the then disconnection of charge and discharge controller field effect transistor Q9, field effect transistor Q8, the lithium battery group is under the trickle safe charging, voltage raises gradually, temperature raises gradually, after lithium battery voltage and temperature reached the numerical value that charges normal, the lithium battery group entered above-mentioned normal composite pulse quick-charge state.
During the discharge of lithium battery group, in the following regular picture of predefined lowest high-current value, when single lithium battery discharge voltage reached 2.4V, automatic disconnection discharge controller field effect transistor Q8 stopped discharge, did not damage because of overdischarge with protection lithium battery group.
