Intro When we check on the status of a Li-ion battery, we will often look at the battery temperature, the SOC, SOH, SOS, SOF and SOE. The SOC, in particular, is important because of its role with the BMS. The BMS monitors the battery based on the SOC and prevents battery overcharge and overdischarge, and…
If you are looking to produce custom car jump starters, you either need to perform research and development yourself or find a strategic partner that will do it for you. It goes without saying that carrying out your own research and development is a capital-intensive venture which isn’t guaranteed to provide the required results. That’s…
Anyone who owns a vehicle should have the right tools in the vehicle, including a spare tire, a jack, and always, a jump starter. A jumper is probably the most used vehicle tool of all time, either for yourself or for someone else in need. If you are an auto repair store, you need to…
Intro Internal resistance ( IR ) is an opposition against the current flow in a lithium-ion battery while it is in operation, and it is an important technical index to measure the performance of a battery. A large amount of internal resistance turns a part of the energy into heat. This becomes a factor for…
Car jump starter is an important tool for drivers. It can help you out during crises. Moreover, it can get your car moving once again. So, you don’t have to be stranded by the roadside. Similarly, it can help you avoid roadside assistance charges. You can jump-start your car by yourself and get going. However,…

So, having a portable solution ready and raring to go is a wise investment. Portable jump starters can get your car up and running without needing another vehicle…
UAV is an actual aircraft that is being commanded via remote control or locally available computers. As part of the UAV system, the battery also needs to be selected according to our needs, such as low temperature, high voltage, high C-rate, etc. Drone batteries come in all sizes, going from hand-dispatched miniature UAVs to enormous…
One of the most sinking feelings any driver has is when they get into their car, switch on the ignition, and – the battery is dead. No matter what they do, they cannot get the ignition to work. The person knows they need to jumpstart their car, they know they should have bought that portable…
The energy density of batteries can be displayed in two different ways: gravimetric energy density and volumetric energy density. The gravimetric energy density is the measure of how much energy a battery contains in proportion to its weight. This measurement is typically presented in Watt-hours per kilogram (W-hr / kg). The volumetric energy density, on…
