How Long is the Battery Life of BYD Cars?

[OJayce]

BYD electric vehicle batteries are designed to power the starting system, ignition system, electronic fuel injection system, and the car's electrical appliances, with a general lifespan of 6 to 10 years or 150,000 kilometers. In terms of service life, ternary lithium batteries last about 1,200 charge-discharge cycles, while lithium iron phosphate batteries can endure around 2,000 cycles. Ternary lithium batteries refer to lithium batteries that use lithium nickel cobalt manganese oxide as the cathode material and graphite as the anode material. Compared to lithium iron phosphate batteries, ternary lithium batteries have higher energy density, better low-temperature discharge performance, and higher charging efficiency, making them the mainstream battery for pure electric vehicles today. Reasons for shortened battery life: Frequent charging and discharging, repeated cycles, can shorten battery life. In cold weather, driving requires significant power, which can severely accelerate battery damage. If the battery is not charged in time, prolonged power deficiency can also lead to battery damage. The use of electrical appliances in the car accelerates battery discharge, shortening the battery's lifespan. Proper use of the car battery is crucial. Below are some battery maintenance methods: If the battery is left unused for a long time, it will slowly self-discharge until it becomes unusable. Therefore, the car should be started periodically to recharge the battery. When the ammeter shows insufficient charge, the battery should be charged promptly. When the electrolyte is low, distilled water or a specialized replenishing fluid should be added. Avoid using drinking purified water as a substitute, as it contains various trace elements that can adversely affect the battery.
