What are the “three electrics” of new energy vehicles? When buying a car, the salesperson is full of “three electrics warranty” and “three electrics for life”, which makes people confused. Don’t worry, after reading this article, I guarantee that you know more than the salesperson in the 4S store!
- Battery – the “big stomach king” of electric vehicles
Official name: power battery
Status in the world: the most expensive part of the whole vehicle (accounting for more than 40% of the vehicle price)
What does it control?
Storage capacity: determines how far you can run
Charging speed: determines how long you have to wait
What should I pay attention to?
Don’t charge to 100% often (just like people feel uncomfortable when they are full)
Don’t charge until 0% (the battery will “starve” and get sick)
The battery life is discounted in winter (a common problem of all electric vehicles)
Cold knowledge:
CATL battery ≈ academic master
BYD blade battery ≈ sports specialty student
Tesla 4680 battery ≈ overseas returnee elite - Motor – the “heart” of electric vehicles
Official name: drive motor
Status in the world: determines whether the car is a “little sheep” or a “grumpy brother”
What does it control?
Acceleration speed (motor power determines the push-back feeling)
Top speed (don’t think of racing with a grocery cart)
Interesting facts
Single motor: economical man (power-saving but lack of stamina)
Dual motor: grumpy old man (four-wheel drive + strong acceleration)
For example:
Wuling Hongguang MINI EV’s motor ≈ electric bicycle PLUS
Tesla Model S Plaid’s motor ≈ electric rocket - Electronic control – the “brain” of electric vehicles
Official name: vehicle controller
Status in the industry: the smartest but the lowest presence
What does it do?
Energy distribution (determines whether to power the air conditioner or the motor first)
Energy recovery (convert kinetic energy into electrical energy when braking)
Battery protection (prevent overcharging and over-discharging)
Hidden skills
Good electronic control can extend the range by 10%
Poor electronic control will make the car “lack of IQ” (such as sudden speed limit)
Important reminder:
OTA upgrade is mainly to upgrade it! (Don’t be annoyed, there may be a new function after the upgrade）
1. “Lifetime warranty” does not mean it is made at random (there are exemption clauses)
2. The warranty may be reduced after the transfer of ownership (pay attention when buying second-hand)
3. Normal battery degradation is not covered by warranty (unless the battery is drained very quickly)
The ultimate three-electric maintenance secret
Battery: charge as you use it, don’t starve it or overcharge it
Motor: Don’t often use the floor to charge, be careful of “premature aging”
Electric control: Upgrade the system in time to keep the “IQ online”
Remember: the three-electric is the “lifeline” of electric vehicles. If you take good care of it, it can accompany you for a few more years. If you don’t take good care of it… the repair fee will make you doubt your life!
