Why does BYD DM-i not have a transmission?
1 Answers
BYD's DM-i technology is an improvement based on Honda's i-MMD technology as pure electric vehicle technology continues to mature, relying more on batteries and electric motors, thus eliminating the need for a transmission. Below is relevant information about BYD: It can meet requirements: If BYD requires rapid acceleration at high speeds, the electric motor will cooperate to drive, which can also meet the demand. However, the efficiency of the motor decreases at high speeds, making it difficult for DM-i technology to accelerate again at high speeds. Economy: BYD is more suitable for urban use primarily, but it can also handle highway and long-distance driving when necessary, though it does not meet the demands of aggressive driving. For conditions requiring prolonged high-power driving, such as extended ultra-high-speed driving, DM-i technology is not up to the task. Adapting to normal driving: Essentially, vehicles with DM-i technology will only enter the engine direct-drive state at speeds above 80. According to highway and road design standards, speeds above 80 km/h are unlikely to encounter significant gradients, and it's impossible to maintain speeds above 80 km/h when climbing steep slopes. Therefore, this technology has no problem adapting to normal driving needs.
