Cost Considerations: Upgrading to lithium-ion auxiliary batteries introduces additional costs to EVs. Although these batteries are more efficient and durable than lead-acid, manufacturers must weigh the trade-off between performance improvements and production costs.
Solid-State Auxiliary Batteries: Solid-state batteries, which are still in the development phase, could potentially be used for auxiliary power. These batteries promise higher energy densities, faster charging times, and improved safety compared to current lithium-ion technology.
Historically, EVs have used lead-acid batteries as their auxiliary power source, similar to ICE vehicles. Lead-acid batteries are cost-effective and reliable for lower power needs, but they are heavy and have a shorter lifespan compared to the newer alternatives.
However, the auxiliary batter is a lead-acid one. Most auxiliary 12v systems use an absorbent glass mat (AGM) battery, a type of valve regulated lead-acid (VRLA) battery. VRLA batteries are lead-acid rechargeable batteries. Unlike conventional lead-acid car batteries, they are fully sealed, i.e., they will not spill.
Instead of using an alternator to charge the auxiliary battery like gas-powered vehicles do, auxiliary batteries in HEVs and EVs are recharged by the HV battery using an inverter/converter. Batteries in gas-powered vehicles are charged via the engine and alternator.
Lead-acid batteries are used as a power source in these vehicles, and it is designed for flash charging and used for the charging process. This power device consists mainly of a hybrid system, which uses 8.6 kWh LED-acid batteries (72V/120 Ah) which are connected in series using the three Maxwell supercapacitors (125 V, 63 F).
