Charging a battery at a high rate can cause damage to electronics and even pose a risk to a person. Discharging at such rates for an extended period of time generates heat in the battery due to the internal resistance, which can lead to a fire or explosion.
Experiments confirmed that charging at high currents has a huge impact, increasing the lifespan of the average test battery by 50%. It also deactivated a much higher percentage of lithium up front – about 30%, compared to 9% with previous methods – but that turned out to have a positive effect.
Running a lithium-ion battery at high current will shorten the overall cycle life of the battery since the internal components such as the anode and cathode will wear out at a faster rate. This means you will get less years of service from a stressed battery cell. Want to know more about Lithium-Ion and battery safety? We answer burning questions here.
When a battery charges, lithium ions flow into the negative electrode for storage. When a battery discharges, they flow back out and travel to the positive electrode; this triggers a flow of electrons for powering devices, from electric cars to the electricity grid.
So, in a plausible scenario the current through the battery will be constrained by its resistance and the power input will be much less than 1500 W. And of that 1500W input, of course quite a few W will still be used to charge the battery. It's the excess power which generates the hydrogen gas and heat.
Even if there is a switched-mode power supply that is technically capable to raise the voltage beyond reasonable values, it won’t necessarily do it. So, in a plausible scenario the current through the battery will be constrained by its resistance and the power input will be much less than 1500 W.
