Ordinary fuel vehicle starter battery
1. Battery category:
Sealed maintenance-free battery & dry-charged battery.
2. Battery principle:
Discharge:
(1) Start: provide a large current supply for the instant start of the vehicle Electricity
(2) DC power supply for parking the whole vehicle: lights, horns, anti- Stealer, trip computer, window lifter, door unlocker, etc.
Charging: After the fuel engine starts, it drives the generator to charge the battery Charge
3. Lifespan:
The warranty period is generally 12 months, and the actual battery life is 2-5 years Varies (commercial vehicles are halved).
Ordinary fuel vehicle
1. Battery type: AGM start-stop battery (commonly used in European cars) EFB start-stop battery (flooded type, commonly used in Japanese cars)
2. Battery principle:
Discharge:
(1) Startup: Provide instantaneous high-current power supply for vehicle start-up and start-up during driving
(2) DC power supply for parking the whole vehicle: lights, horns, anti-theft devices, driving computer, window lifters, door unlocking, etc. Charging application: After the fuel engine is started, it drives the generator to charge the battery
3. Life: The warranty period is generally 12 months, and the actual life of the battery ranges from 2 to 5 years (half of the operating vehicle)
4. Remarks: Frequent start-up during driving, the start-stop battery needs to have the characteristics of high cycle and high charging acceptance efficiency.
Hybrid & Plug-in Hybrid
1. Battery type: Lead-acid battery:
AGM start-stop battery (commonly used in European cars) or EFB start-stop battery (flooded type, commonly used in Japanese cars) Lithium battery: ternary or lithium iron phosphate battery pack (the number of batteries is small)
2. Battery principle: Discharge:
(1) Lead-acid: Provide 12V power supply for the whole vehicle, such as driving computer, lithium battery BVS, door unlocking, multimedia, etc., but no instantaneous high-rate discharge is required.
(2) Lithium battery: Lithium battery or pure electricity Charging in discharge mode while driving: After the vehicle starts to process the “READY” state, the lithium battery pack will charge the lead-white battery through the step-down module. When the vehicle is running in fuel mode, the engine will charge the lithium battery pack.
3. Lifespan: The warranty period is generally 12 months, and the actual life of the battery ranges from 2-5 years (the operating vehicle is halved)
4. Remarks: The plug-in hybrid can drive about 50KM in pure electric mode, and the pure hybrid vehicle cannot Pure electric driving.
New Energy Vehicle
1. Battery type: Lead-acid battery: AGM start-stop battery (commonly used in European cars) or EFB start-stop battery (flooded type, commonly used in Japanese cars) Lithium battery: ternary or lithium iron phosphate battery pack (more batteries)
2. Battery principle: Discharge:
(1) Lead-acid: Provide 12V power supply for the whole vehicle, such as driving computer, lithium battery BMS, door unlocking, multimedia, etc., but no instantaneous high-rate discharge is required.
(2) Lithium battery: pure electric driving Charging in discharge mode: After the vehicle starts to process the “READY” state, the lithium battery pack will charge the lead-acid battery through the step-down module, and the lithium battery pack needs to be charged by a charging pile.
3. Life: The warranty period is generally 12 months, and the actual life of the battery ranges from 2 to 5 years (half of the operating vehicle)
(1) Lifespan: Different types of vehicles use different charging and discharging methods for batteries, but they are all in a state of frequent use. According to the information learned from dealers and car repair manufacturers, the lifespan of 12V lead-acid batteries is basically the same, 2-5 Years vary.
(2) Irreplaceability: Due to the instability of lithium batteries at extremely high or low temperatures, the driving computer and BMS of the vehicle need to be powered by a 12V battery, and a safety self-inspection of the lithium battery pack should be performed before the vehicle is driven, and even cool or heat the battery to ensure the normal discharge of the lithium battery and the safety of driving.
